素晴らしい!
Bought this bit to drill some holes in Metal (2mm MS). Seems to work with a hand drill but I wasn't very successful when i reached a dimension of about 15mm dia, I will have to check it again by mounting on a drill press. Expecting my Hilda drill bracket order from Banggood very soon. Hoping that it will make the job easier to increase the hole dia to 20mm.
