Spotlight on Ingersoll Rand 1/2″ Impacttools

Ingersoll Rand is a well-known name around the industry.  From air tools to air compressors to cordless tools, Ingersoll Rand manufacturers an excellent product used worldwide by mechanics.  This spotlight article is about the IR impacttool line, specifically the ½” version as that seems to be a highly popular size of impacttool.

Let’s start off with one of the most popular ½” impacttools on the market, the 2135TiMAX.  This tool “sets the standard for performance with the best power to weight ratio on the market in its class.”, according to the experts at Ingersoll Rand.  With 780 ft-lbs of MAX reverse torque and weighing less than 4 lbs, it’s the best power-to-weight ratio in its class.  This tool also comes with a free two-year limited warranty with the tool registration at

Ingersoll Rand 2135TiMAX

Perfect for both industrial and vehicle service work, the new 2135TiMAX delivers maximum power and control, along with unmatched reliability.


Next up is a “powerful, durable and reliable workhorse whose reputation is built on helping you build yours, because you don’t do a job halfway, and neither do our tools”. This impact has an amazing 1,350 ft-lbs of nut-busting torque and 930 ft-lbs of max reverse torque.  Again, Ingersoll Rand has outdone itself by making this hard working impact only 4.6 lbs.  The manufacturer states, “Born from the legendary durability of the Ingersoll Rand 2135 Series, the 2235 pushes toughness to the next level.  It’s built with a titanium hammercase, steel-wear plate and composite housing that protects the tool from the harshest environments.”

Also available in a Quiet version: 2235QTiMAX

The 2235 Series is a finely tuned workhorse, from its components to its technology, to be the impact wrench you can always count on to get real work done.

The 2235 Series is a finely tuned workhorse, from its components to its technology, to be the impact wrench you can always count on to get real work done.

As always, Ingersoll Rand has delivered two of the best impacttools on the market today.  After using both of these tools, I can safely say that I’m dually impressed.  If you are looking for a great brand, great product, and reliability…Ingersoll Rand 1/2” impacttools are the way to go!

What is a Feeler Gauge?

What is a Feeler Gauge?
By: J. Dillinger

I have seen a few of these around but never knew the purpose of them. Let’s break down what a feeler gauge is.

Feeler gauges are used to measure the gaps in widths between 2 objects. Feeler gauges are made of different thicknesses and lengths. There are two types of units that the feeler gauge uses to measure, the imperial (thousandths of an inch) and metric (millimeter). Feeler gauges are made out of either blades or wire. The wire feeler gauges are used to measure spark plugs.

The most common Feeler gauges are made from high-quality carbon steel and have a very smooth finish. Blade Feeler gauges can also come in an assortment of stainless steel, brass and plastic. However, metal feeler gauges are easier to maintain and have a better wear resistance.

To use a feeler gauge make sure you examine them before each use. Do this by spreading them out making sure they rust-free, but slightly oiled for easy movement. Select one of the smaller blades or wires and try inserting it into the space. If it slips out easy choose the next side up. When both sides of the gauge touch the gap and it moves with gentle pressure, then you’ve found the correct feeler gauge for that gap.

Blade Feeler Gauge

A blade feeler gauge can also be called a flat feeler gauge. A set generally comes in a holder and contains a series of blades with different thicknesses that are stamped for easy identification. A blade feeler gauge is generally flexible and can be used to reach hard places.

Blade Feeler Gauge Example (KDT161)

Wire Feeler Gauge

The wire feeler gauge is a series of round wires with different thicknesses in a holder usually bent into a U shape and are less flexible than the Blade Feeler Gauge. These wire feeler gauges are more frequently used in the automotive industry.

Wire Feeler Gauge Example (KDT2327)

In case you need a combo unit, there are a few manufacturers that make blade/wire feeler gauge sets. Sometimes having one tool is better than having to keep track of two!

Pig Mat Customer Review

Here at National Tool, we receive “fan mail” from our customers on a regular basis.  We pass on the comments and helpful tips to our employees as training tools to make our business better.  But, we’ve received a rave review on a fairly new product line and we decided to share it with our customers.

We would love to hear your feedback on a product you’ve purchased, good or bad! Send us an email with your review and you may be featured on a future blog!

Hi National Tool,


I wanted to share a story with you about a product that we recently purchased from you all, The Pig Mat roll. My family and I attend car shows all of the time and if we have a leak, it is a mess to clean up! We have been looking for something that was light-weight and easy to use. This new pig mat towel was so easy to use and we didn’t have to clean up a mess after using them. We placed a couple sheets under the engine compartment while we were at an indoor show and WOW does it work! The oil decided to leak out and it could have gotten everywhere. It was so nice to be able to pick up the mats and just throw them away. A neighbor of ours at the show was so impressed that we gave them a couple to use and they are in love with them also. I would recommend these to anybody out there and you’ll definitely be getting more of our business soon!

P.S. I’ve included a picture of two of our cars that you can share with your employees and your customers.


Thank You,

Jerry D.

It’s Gettin’ Hot in Here!

The hot summer weather is blowing in quick! As important as it is to prepare your vehicle for winter, it is just as important to prepare it for the hot summer temperatures. Below I have listed a few tips to get your vehicle in tip-top shape for this summer season.





  • Check your tire pressure – If your tires are under-inflated, this will cause the tire to bulge which will add pressure to the sidewalls of the tire. After enough heat and pressure has affected the tire, BOOM! It will eventually blow. Also, n over-inflated tire makes less contact with the surface of the road and can cause you to hydroplane during the spring and summer storms.
    See what tire pressure gauges are in stock HERE!

Did you know?? – Tire pressure changes with rising temperatures, approximately one to two PSI for every 10 degree increase in outside air temperature.




  • Check your oil and oil filter – ROAD TRIP!!! Wait! Before you leave, make sure you check your oil and oil filter in the vehicle. Long distance drives mixed with hot temperatures can lead to an overheated engine.
    Need to change the oil? Drain Pans make your job easier!

Did you know?? – Oil keeps hardworking engine parts running clean, smooth and cool.





  • De-winterize – Check all the fluids in your vehicle and check for leaks. If you are in extreme snow climates and have snow tires, take them off. Snow tires cause extra weight to the vehicle and are not fuel efficient. Also, clean the undercarriage of the vehicle from salt on the roads.
    Can’t see under your car? These inspection mirrors will help!

Did you know?? – The salt that is used to melt ice and snow on roads can get caked on the underside of your car and begin to eat away at the metal.




  • Check hoses, belts and filters – It is very important to keep the engine cool when driving in the summer heat. Check all of your hoses and belts for cracks, leaks or loose connections. Also, change your air filter if it is clogged with salt or other road debris.

Did you know?? – Replacing a dirty or clogged air filter can improve gas mileage by as much as 10%.

belts and hoses


  • Replace your wipers – The winter weather is hard on your wipers. You know, when you get impatient waiting for the windshield to defrost so you use your wipers to speed it up? Ya, I’m guilty. Also, it is important for your wipers to work for the spring and summer storms. I would hate to be stuck on the highway when a sudden storm hits without good wipers!

Did you know?? – At night, a storm can decrease visibility by 15 to 20 feet in front of your vehicle.



  • Keep your battery clean – Dead batteries are common in both winter and summer due to the extreme temperatures. You should detach the battery cables and clean the terminals often. Makes sure that your battery is strapped in correctly and is secure. Also, always make sure you are buying the correct battery for your vehicle if it needs to be replaced.

Did you know?? – Summer heat can speed up the chemical reaction inside a battery, causing the battery to be overcharged. This reduces battery life significantly.



  • Maintain your AC – Most of the time, the cause of a malfunctioning AC is because of low refrigerant. This could be caused by a leak in the system. It is best to have a professional check out the problem since modern AC systems are so complex.

Did you know?? – The best way to tell if your air conditioner has a problem is if it can’t generate or maintain air temperatures that are 50 degrees Fahrenheit below the outside air temperature.

A Must Have in Every Vehicle This Time of Year…

The new Schumacher SL1 charger/jump starter is a must have.

It can charge your cell phones, mp3 players and tablets up to 2x faster than a regular charger. It is small enough to fit into your glove compartment and it is light weight. This item will also jump start your vehicle…you simply plug one jumper cable into the battery and the other one onto something metal…press the jump start button and your car will start! It’s so easy!

It also comes with a wall charger and a car charger for the unit. You can still use the car charger even if your vehicle will not start and the battery is dead. This would not only make a great gift but it is a must have item for all people who own a vehicle. Not to mention, it’s inexpensive.

I know with this crazy weather I’ll be getting myself one, will you?

How To Check The Oil In Your Car

Have you ever wondered if you were doing something right?  Don’t worry…I wonder that every single day! We’ve decided to take the guesswork out of checking the oil in your car.

Checking the oil in your car is an important maintenance check. This quick and easy check can help keep your car running smoothly. An easy way to remember when to check the oil is every other time you fill your car up with gas. All you need is a paper towel or a rag (which you can get free from most gas stations).

 Follow these steps below to Check the Oil.

  1. Make sure that you have the engine turned off.
  2. Open the hood and find the dipstick.
  3. Pull the dipstick out and wipe off any oil from the end.
  4. Place the dipstick back in the tube and then pull it out again.
  5. Look at both sides of the dipstick and where the oil is on the end.  If the oil is below the minimum mark you will need to add oil, anything above minimum should be good until your next check.
  6. Once you are done checking the dipstick, put it back into place and make sure that it is secure. Then close the hood.

Performing this simple 2 minute check could save you a ton of dough down the road.  If you prefer not to get your hands dirty and you live in a part of the country that has a full-service gas station…by all means stop there!

Unique Gift Ideas For That Hard-To-Buy-For Man!

Why spend days, weeks, even months trying to find the best gift for your husband, brother or teenage son?

When you ask your husband/brother/son what he would like for Christmas this year, what do you think his answer will be?  The standard “I don’t know”, “tools”, “money”, “I’ll love whatever you get me”??

Well I found a few things that Schumacher came out with this year that will be sure to delight all of the men I know. *hint hint – the SL-1 is on the top of my Christmas list*

I recently bought the SHUSL-5 and ended up losing it to my 17-year-old son.  It works great for charging your iPhone.  He was almost dead and plugged his phone into the Fuel Pack and let it charge while watching a show and it didn’t take much time at all for his phone to be fully charged.  Needless to say, I never got the Fuel Pack back and had to buy myself another one!

Whether you decide to go for the SHUSL-3, SHUSL-4 or SHUSL-5, you can’t really go wrong.  These are all great units and will be treasured by all who receive them!

Make sure you also check out the SHUSL-1 and the SHU-SL-360R.  Those are top picks on the Mechanic’s List this year.

The SHUSL-1 is also a great contender when it comes to picking a jump starter to leave in your car this winter.  I recently wrote a blog called Picking the Right Jump Starter For You to give everyone some ideas about which jump starter will work best for your vehicle.  Make sure you check it out before you buy a new power pack.
