4mm HSS 5‑Flute Carpentry Reamer Key benefits Precise, clean holes: Brad point tip centers instantly and prevents wandering for accurate starts and straight holes. Smooth, fast cutting: Five flutes evacuate chips efficiently and produce a cleaner hole wall and edge. Durable and reliable: High-speed steel (HSS) resists wear and heat for consistent performance across woodworking tasks. Versatile function: Designed for drilling, chamfering and light countersinking in timber for a finished, ready-to-assemble result. Single-piece construction: Solid one-piece bit reduces vibration and the risk of slippage or breakage. Main features Diameter: 4 mm — suitable for small pilot holes, dowel and pin work, and precision joinery. Tip and geometry: Brad point with twist design for accurate starts and controlled cutting. Flutes: 5 flutes for improved chip removal and a smoother finish compared with fewer-flute bits. Material: High-speed steel (HSS) for long life and dependable cutting under normal woodworking conditions. Typical applications Dowel and pin holes for furniture assembly: drill precise 4 mm pilot holes for dowels and alignment pins. Cabinet and hinge preparation: create accurate pilot holes and light countersinks for concealed fittings. Finish carpentry and trims: drill clean holes for screws and anchors where a neat edge and controlled countersink are required. Practical notes Use at appropriate spindle speeds for wood species and keep feed steady for the best finish. Clear chips periodically to maintain cutting efficiency. Secure the workpiece to avoid movement while drilling. This single-piece 4 mm HSS, 5-flute reamer is a practical addition to any woodworking toolkit when accuracy, clean finishes and reliable cutting performance are needed.
