Irwin 4X Blue Groove Flat Wood Drill Bit

The 6mm IRWIN® Blue Groove 4X Flat Bit is the ideal choice for smaller diameter drilling tasks in timber, perfect for pilot holes, furniture assembly, and precision joinery work. This compact size offers exceptional control whilst maintaining the impressive performance characteristics of the Blue Groove range.
