Review on Bosch BL2161 Fractional Reduced-Shank Drill Bit by Ben Demers

I bought 4 17/32 inch bits thinking I'd use them all but unfortunately I'll be back 3 I was able to over-drill 4" stainless steel and 2" clutch steel (not sure what kind it is) with just 1 bit. It's still good and sharp. Of course, I used solid drilling technique (a lot of lubrication, relatively low speed and economy). a bit of overheating, took my time.), but I'm still impressed! Great product! I can recommend it!
