High-speed steel cutting bit for deburring, chamfering, cutting and enlarging holes Key benefits Precise, clean edges: Designed to remove burrs and chamfer hole edges for a smoother finish and better part fit. Durable cutting performance: Manufactured from HSS (high-speed steel) for hardness and reliable edge retention under normal use. Reduced corrosion and heat buildup: Surface coating minimizes corrosion and helps dissipate heat for longer life and more consistent cuts. Versatile material compatibility: Works on a wide range of materials including steel, brass, wood, plastic and similar substrates. What it does Deburrs and cleans up drilled holes. Creates chamfers for countersinks and fastener seating. Cuts or enlarges existing holes with controlled material removal. Practical details and usage tips Select the appropriate diameter and feed rate for your application to achieve the best finish. The HSS construction provides strength for metalworking while remaining effective on softer materials like wood and plastic. The coating helps reduce overheating and corrosion during repeated use, improving consistency and tool life. Typical applications Metal fabrication: Remove burrs and chamfer holes in steel or brass parts before assembly. Maintenance and repair: Enlarge or clean up bolt holes in machinery and automotive components for proper alignment. Carpentry and plastic work: Chamfer and tidy holes for fasteners and fittings in wood and plastic panels. Materials and performance summary Material: High-speed steel (HSS). Coating: Protective coating to reduce corrosion and heat. Functions: Deburring, chamfering, cutting, enlarging holes. Compatible materials: Steel, brass, wood, plastic, and similar materials. Choose this HSS cutting bit when you need a reliable tool for producing clean hole edges, consistent chamfers, and controlled hole enlargement across a range of common workshop materials.
