Description:

A straight shank design is more suitable for many electric drills (here is not included).
Twisted flutes will make the drilling more easy.
High-speed steel drill bits are much more resistant to heat, suitable for drilling metal, hardwood, and most other materials at greater cutting speeds than carbon steel bits, and have largely replaced carbon steels in commercial applications.
