Drilling through concrete, tile, brick or glass takes a bit that will not crack halfway. The strengthened alloy head prevents bit cracking and prolongs the lifespan, and the anti slip shank keeps the bit from slipping in your hand. Each one fits any standard electric drill.

Made from a sturdy hard alloy and 6542 HSS carbide, these HSS drill bits and carbide drill bits have a W-type flute that reduces resistance, and a 135 degree top corner on a triangle shank. As drill bits for metal and wood they work as a metal drill bit in steel and alloy and a wood drill bit in wood, and as a tile drill bit, glass drill bit and brick drill bit they cut tile, glass and brick without switching tools.
