🔩 Drill America DEWCSK1 1/4 90 Center: Versatile and Reliable Drill for Precise and Effortless Drilling Review

This is a high speed steel so it dulls faster than carbide when used on wood (or sheet metal which I wouldn't recommend). However, I bought this to get a perfect 60 degree internal bevel on a piece of PTFE tubing for a 3D printer and for that it works great and can last forever. Cutting PTFE will never dull this tip, so it belongs in the toolbox and will be used for a long time.

This product came with some rust on the shank and a protective rubber coating on the cutting faces. I removed the "protective" finish and found that there was more rust in the cut zone than on the shaft. Really guys? A brand new tool shouldn't arrive in such bad condition. It seems to cut "well" (have only used it on aluminum so far, not steel), but I'm not sure I have high hopes for its durability given how it's been received.

item was exactly as described. I read a negative review but didn't consider it because the person said he didn't get what he ordered but never said he did. The only thing I could think of was that they wanted a countersink for a 1/2" screw. This has a 1/2" body that will only fit a propeller with a main head diameter of 1/2" or less. Also, most American screws use 82 degrees instead of 100 degrees. I was very happy with my purchase.
