HSS Drill 4241 cutting edge with black chamfer drill body made from No. 45 steel. Single flute edge chamfer 90 degree for precise, repeatable chamfers. Key benefits Durable cutting performance: the HSS Drill 4241 cutting edge delivers reliable wear resistance and maintains sharpness for extended use. Strong, stable body: Black chamfer drill body material No. 45 steel provides rigidity and impact resistance for workshop and on-site tasks. Accurate 90° chamfers: Single flute edge chamfer 90 degree produces consistent, clean chamfers and simplified chip evacuation for smoother finishes. Versatile accessory: Designed as a practical drill accessory for a wide range of chamfering and edge-preparation tasks. Function and compatibility Purpose: Designed to chamfer and deburr edges at a precise 90° angle; ideal where a consistent bevel is required. Compatibility: Intended as a drill accessory to be used with standard drilling setups and common tooling arrangements in fabrication, maintenance, and general workshop use. Performance: Single-flute geometry improves chip control and minimizes chatter for a cleaner edge on each pass. Practical use scenarios Mechanical assembly: Create clean 90° chamfers on drilled holes to ensure proper seating of fasteners and to remove sharp edges before assembly. Metal fabrication and maintenance: Deburr and bevel metal plates, brackets, and parts after drilling to speed up finishing and reduce rework. Workshop and repair: Prep edges on machine components or parts during repair work to restore fit and prevent stress concentrations. Materials and care Cutting edge: HSS Drill 4241 Body: Black chamfer drill body material No. 45 steel Use recommended machining practices: secure the workpiece, use appropriate speeds and feeds for the material being worked, and inspect the cutting edge for wear before use. This tool provides a straightforward, robust solution for producing consistent 90° chamfers with durable construction and reliable cutting performance.
