- HSS construction for durable performance: Made from HSS4241 steel, this lip and spur bit is designed to hold up through extended woodworking projects. The resilient material works reliably in both hardwood and softwood, delivering clean entry and dependable cutting. - Universal round shank for easy fitment: Features a precisely formed 9.5 mm (3/8 inch) round shank that fits securely in virtually all standard electric drill chucks. Prevents unwanted rotation during operation and simplifies tool changes for a smoother workflow. - Accurate self-centering point for clean starts: Honed spur tip geometry penetrates wood surfaces cleanly without the need for a preliminary indentation. It stays on true course on angled or irregular work pieces and reduces wandering on delicate veneers. - Depth control you can trust: Includes a 19 mm outer diameter depth collar that slides along the 63 mm cutting length and locks at the desired setting. This prevents over-penetration in cabinet back panels and other depth-sensitive applications. Typical applications: - Installing cabinet hardware or hinges in hardwood or softwood panels, where clean, starting holes are essential. - Drilling precise starter or dowel holes in furniture parts and veneers, with minimal tear-out. - Working on cabinet back panels or thin panels where controlled depth ensures consistent hole depth and reduces surface damage.
