Dewalt DT4588-QZ Rapid wood drill bit 76 mm. The Rapid wood drill bit is an extra-sharp drill bit for the cleanest drilling results with very fast drilling progress. Equipped with two extra-sharp cutting edges for particularly fast drilling progress, an aggressive self-retracting centre point for fast penetration into the material and a non-slip shank for optimum hold in the drill chuck, it guarantees comfortable drilling. It is suitable for use in power drills (cordless and corded) for clean and precise through-holes in hard and soft wood, wooden floorboards, old building ceilings, plasterboard and more.
