Customer Reviews

Virtually indestructable
That's right. Our shop uses these 231's for regular duty and tire service. These things last for years despite being dropped on the floor, not oiled regularly, and zero maintenance. Typically the power selector knobs are the first thing to go on these wrenches. If you need good performance and a tool that will last a long time then this is your wrench.

From a professional
I'm a professional diesel mechanic, and I will not buy any other impact but this one. My first one lasted me for 10 years, through drops, kicks, no oiling, etc. I only don't have it anymore because I moved and sold it to a friend who still uses it. I have put this thing head to head with impacts 3 times the price of this one, and it has always been the strongest and most powerful. Most of the people in my last shop borrowed mine because it was the most powerful in the shop, and nearly everyone at my new shop has one. Buy it, you won't be disappointed.

Works Great!
I needed a impact wrench for rotating my tires. Originally I bought a Harbor Freight Special...... and it wouldn't turn the lug nuts on my Silverado or Trailblazer for nothing. I bought this baby with my money from Christmas and I am very happy. I rotated my tires this weekend without a problem! I was concerned with the compressor I had. I was worried it wasn't big enough for tools like a impact wrench. I have a Makita MAC2400 4.2 CFM and it was good enough for this wrench. So far I highly recommend!
