Makes perfectly sized smooth holes in wood thanks to the upgraded version carbide blades and reinforced steel body. The quality, durability, craftsmanship, and functionality of these upgraded Carbide Blade Reinforced Forstner Bits is unbelievable for the price. Highly recommended over spade bits as well as lesser quality Forstners bits that leave a useable hole but very rough finish and sometimes causes cracks and splinters.. Thank you for supporting America and it's Armed Forces!!

This thing worked out perfect for the job that I needed. It is incredibly sharp and doens't catch on the material like other forstner bits I've used.

This bit make a good cut with almost none tear out. If you are looking for a 60 mm bit, this is well recommended. I have 4 stars because it was advertise as 2-3/8” and it is not. I had to buy another bit to actually get the right size hole and avoid to sand the circule hole edges. If you have time for the extra work and run for error (no need for a perfect circle), this bit will make the trick!In the shared pictures you can see 2 pvc fittings that are 2-3/8” OD and the one in the 60 mm hole made with this bit barely fit into the whole leaving about 80% of the fitting out, while the one in the hole made with the 2-3/8” bit went all way thru.

Bought the 28mm Forstner to install 3 security door viewers, I used on it wood (cut like a champ), thin metal (took longer as expected, yet still cut nicely) and fiberglass (not a problem cutting). It was a pleasure to have precise, easy cutting of material, this bit shows no signs of wear after the three installs, highly recommend!

I have Forstner bits, but I needed one that would bore a smooth flat hole through decal covered wood and plastic without tearing the decal or painted surface around the hole. I found this bit and gave it a try. Worked perfectly. Gave me by far the cleanest hole I have seen. Highly recommend it.
