I was skeptical about this drill because I've never heard of the brand name before. However, it preformed pretty good and drilled through a solid roller camshaft that I was making a lamp out of. I used every bit of the drills length drilling the cam from both ends. I did thin the web before using it because I didn't want my work piece to work harden, as it tried to a few times. I'd recommend this drill to anyone and I'd buy it again.
