Spyder Stinger Drill Bit Set - 10-Piece - High-Speed Steel - 1/4-in Hex Drill Shank is rated
Rated 2 out of
Stick to Diablo
Very sharp out of the box. Nice case. With clean metal and wax they cut well, but definitely keep away from general purpose use. If you happen to drill a little too deep and so much as catch concrete for a half resolution the bit is rendered useless.
Seems like a great coating but subpar alloy
