Irwin 4X Blue Groove Long Flat Wood Drill Bit

The Irwin Blue Groove 4X Long Flat Bit in 32mm x 400mm represents the largest diameter in this extended reach range, delivering exceptional drilling performance for very substantial applications in timber construction. This impressive size is perfect for creating holes for 32mm waste pipes, larger soil pipes, substantial mechanical installations, heavy-duty ducting, and major structural penetrations through deep timber members.

With its robust 32mm cutting diameter and extended 400mm shank length, this bit is the professional's choice for the most demanding large-diameter drilling applications through floor joists, deep wall cavities, and roof timbers. The patented Blue Groove technology features an advanced groove point and cutting edge that cuts cleanly through timber rather than scraping, delivering speeds up to 4 times faster than conventional flat bits. The parabolic scoop design maintains excellent chip removal even at this substantial diameter, ensuring smooth, controlled operation.

Engineered with a 10% larger diameter shank for maximum strength and an improved 17° relief angle for efficient cutting action, this bit combines superior drilling speed with the exceptional durability demanded by the most intensive professional applications.
