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.
The Irwin blue Groove 4X bit set includes 8 pieces in the following sizes: 12, 16, 18, 20, 22, 25, 28 and 32mm. Now, your best bits are right where you can see them. The newly redesigned IRWIN Accessory Storage Cases have clear lids so you can keep track of your bits with just a glance. Each case has a pivoting mechanism that holds bits securely, so you’ll always know they’re in place. Plus, a connectable case system lets you interlock different cases–no matter the size. All so you can stay organized job after job. Full interchangeable with the Dewalt Tough Case Tstak system and Dewalt caddy.
