Exceptional durability: forged from high-grade black steel to withstand repeated use and extend tool life. Built to hold up under demanding woodworking tasks. Six sizes included (6 mm, 8 mm, 10 mm, 12 mm, 16 mm, 19 mm): covers a broad range of common hole diameters so you have the right cutter for most wood-joining, doweling, and hardware-installation jobs. 6.35 mm (1/4") hex shank for secure, universal compatibility: fits standard cordless drills, impact drivers, and drill presses with a 1/4" hex chuck for quick bit changes and a firm connection under load. Five-flute design for faster chip removal and cleaner cuts: the multi-flute geometry evacuates wood chips efficiently, reducing clogging and heat build-up and improving cutting speed and surface quality. Smooth woodworking performance and clean finish: engineered to cut wood efficiently and produce consistent, seam-free results. Zinc-plated for added corrosion resistance and longer life in workshop conditions. How this product solves problems Saves time and effort: the five-flute cutter and optimized geometry reduce rework from tear-out and clogging, so you complete cuts faster with fewer interruptions. Reduces tool change and setup friction: the 1/4" hex shank provides instant compatibility with common drivers, eliminating adapters and simplifying workflow. Versatile size range: one set covers multiple tasks, reducing the need to buy single-size bits separately. Typical use scenarios Cabinet and furniture assembly: drill clean, accurate holes for dowels, bolts, and hardware when installing hinges, drawer slides, and connectors. Carpentry and trim work: cut neat holes for plugs, plugs for repairs, and pass-throughs for wiring in soft and hardwoods. General workshop tasks: quick hole cutting for prototypes, jigs, and fixture building where consistent finish and fast chip removal improve productivity. Key specifications at a glance Material: high-grade black steel Shank: 6.35 mm (1/4" hex) Sizes included: 6 mm, 8 mm, 10 mm, 12 mm, 16 mm, 19 mm Flutes: five-flute design Finish: zinc-plated for corrosion resistance What to expect in use Secure fit in standard drill drivers, stable cutting with reduced wobble. Faster chip evacuation and less clogging compared with two- or three-flute cutters. Clean edges and reduced tear-out on typical woodworking materials. Recommendations Use at moderate speeds appropriate for the wood species to maximize life and finish quality. Clear chips periodically during extended cuts for best performance. Store dry to preserve the zinc plating and steel integrity. This set is designed for woodworkers, carpenters, and DIYers who need durable, versatile cutters that deliver cleaner cuts and reduce downtime.
