Works great with the helicoil set. Shipping was very expedient.

Renewing a very old Industrial Air Conditioner Pump that was considered beyond repair. The pictures show that it was repairable and is working great . The stainless steel ensures that the next time the seals need replacement I will not have to cut it off of the Base as I did this time . The bit drilled a 5/8 hole where a 1/2 in hole was . Mot an easy task as you might think. Standard HSS Bits snapped off

No delivery charges if you pick the items up at your designated store makes the purchase great. Good price and no delivery charges for a couple of days wait is well worth it. I would purchase things this way again to get items I need that aren’t normally carried in the store but available on-line. It works if you make a plan and stick to it.

worked perfectly on the frame of my Dodge Ram 1500. I didn’t start off with that bit, I started with 3/16, then 3/8, then the the 17/32 so I could pass a 1/2″ bolt through it. As a result my tip was untouched.

I used this drill bit to enlarge a hole in hard steel so I could thread 5/8″ coarse threads.The bit cut like crazy with no rounding of the outside points on the drill bit cutting surface.
