Irwin 6 Piece Blue Groove Flat Bit Set 4 X Faster Cut 10, 13, 16, 19, 22 & 25mm

This blue Groove 4X drill bit set from Irwin uses a patented design for the groove point and cutting edge. The cutting edges cut the timber 4 times faster than standard spade bits, without scraping. The parabolic scoop optimises control and the removal of wood chips.

These drill bits have an increased relief angle from 12° to 17°. The large shank is 152 mm in length and 10% larger in diameter for added durability. The grooved hex shank prevents slipping in the drill chuck or bit extension.

Typical applications include carpentry, electrical installation, plumbing and general building.
