Irwin 4X Blue Groove Long Flat Wood Drill Bit 6mm 400mm

For precision drilling in wood where a smaller diameter hole is required at depth, the Irwin Blue Groove 4X Long Flat Bit delivers consistent accuracy and efficient chip removal. Its extended 400mm length makes it the ideal choice for deep pocket boring, routing cables, or plumbing installs through thick timber framing. The specially formulated Blue Groove coating reduces friction and heat build-up, allowing you to drill faster with less effort while extending the life of the bit.

- Precision-ground spur point ensures clean, accurate starts without wandering

- 6mm diameter suits fine joinery, pilot holes, and small conduit passages

- Extra-long 400mm shank reaches through multiple layers of timber or deep joists

- Blue Groove coating minimises resin build-up and corrosion for longer service

- Flat blade design with sharpened cutting edges provides rapid chip clearance

- 4X designation indicates enhanced durability over standard flat bits

- Fits standard 6.35mm (1/4 inch) hex chuck adaptors for easy use in power drills

Whether you are a professional carpenter or a dedicated DIYer, this bit delivers reliable performance in hard and soft woods alike.
