6-piece HSS chamfer drill bit set for woodworking. Five-flute design with a 1/4 inch hex shank for fast, secure bit changes and reliable countersinking in one pass. Key features Five-flute cutting geometry: smooth cutting action, clean chamfers, and reliable countersinking in a single step. Sizes included: 6, 8, 9, 12, 16, 19 mm — covers common screw heads, hinges, and joinery needs. Five chamfering operations: versatile edge finishing across multiple project tasks. 1/4 inch hex shank: fits most drills, drivers, and impact drivers for quick changes and a solid grip. Material: high-speed steel (HSS) for durability and heat resistance during woodworking. Why you need it Produce clean edge finishes and flush screw seating to reduce sanding, filling, and rework. Combine drilling and countersinking in fewer steps to save time on repetitive tasks. Wide size range handles a variety of hardware and joinery situations so you carry fewer specialty bits. Hex shank compatibility lets you switch bits fast and use the set with standard drills, drivers, and impact drivers. How it solves common problems Minimizes chip-out at edges and entry points by using a dedicated chamfer geometry. Eliminates the need for a separate countersink tool when creating flush-mounted screw holes. Heat-resistant HSS construction keeps cutting performance consistent during extended use. Use scenarios Install cabinet hardware: drill and countersink screw holes so hinges and handles sit flush with the surface. Finish furniture edges: create neat chamfers on shelves, frames, and trim for a professional appearance. Prepare joints and passes: chamfer dowel or cable entry points to ease assembly and reduce splintering. Kit contents Six HSS chamfer drill bits with 1/4 inch hex shanks: 6, 8, 9, 12, 16, 19 mm. This compact set delivers function, compatibility, and durable performance to help you achieve precise, consistent results on wood projects.
