Drill Bits & Accessories

The Irwin 88932 Speedbor Flat Bit 32mm × 160mm is a large-diameter, long-reach wood boring flat/spade bit in the Irwin Speedbor / Blue-Groove family. It is designed for tasks requiring a clean, large hole through timber, wood products, or structural wood members. The Blue-Groove point and cutting edge design help improve chip removal and reduce splintering at the exit, while the length gives reach into thicker or recessed wood areas. It is intended for use in carpentry, framing, construction, plumbing, or electrical work where large clearances are needed through wood.

Features:
Blue-Groove point and cutting edge for faster chip removal and enhanced drilling speed.
Double spur or scoring edges to help reduce breakout and produce cleaner hole edges.
Large 32mm cutting diameter allows for larger holes in structural and non-structural wood components.
Extended length of 160mm gives reach into deeper or recessed timber surfaces.
Reinforced, robust shank design to resist bending and slipping under load.
Hardened steel construction for durability in heavy use and demanding environments.
