Description
This blue groove flat 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.
These stubby drill bits are 10cm (4in) long, making them ideal for drilling through joists or in enclosed areas. Suitable for holes up to 5cm (2in) deep.
8 piece flat wood pieces in the following sizes: 12, 16, 18, 20, 22, 25, 28 and 32mm.
