Wolfcraft 1 Enlarging Mill HSS with Hexagon Shank — cutting tool for enlarging holes

Wolfcraft 1 Enlarging Mill HSS with Hexagon Shank is a high-speed steel cutting tool engineered to enlarge and ream existing holes in metal, wood and selected plastics. The tool features a hexagon shank that fits securely in compatible chucks and bit holders, providing stable torque transfer during drilling and reaming operations. Its HSS cutting edges are designed for durable performance and to produce clean edges and accurate hole diameters when used at appropriate speeds and with correct feed.

Advantages

The HSS construction offers good wear resistance and heat tolerance for repeated use on a variety of materials. The hexagon shank design prevents slippage in chucks and quick-change bit holders, improving control and safety. The cutter geometry is optimized to reduce burrs and deliver a smooth finish around enlarged holes, minimizing post-processing. The tool is compact and suitable for both workshop and mobile site use.

Suitable for

• Enlarging drilled holes in metal parts
• Reaming or sizing holes in wood
• Adjusting hole diameters in certain plastics
• On-site repairs and workshop machining tasks

Key specifications

• Material: high-speed steel (HSS)
• Shank type: hexagon shank for secure holding
• Intended use: hole enlarging and reaming
• Compatible materials: metal, wood, selected plastics
• Application environment: workshop and on-site use

How to use

Select a drill or bit holder compatible with a hexagon shank and secure the tool firmly. Start at low to medium spindle speeds appropriate for the work material and apply steady axial feed without excessive lateral force. For metal work, use cutting fluid to reduce heat and improve chip evacuation. For wood and plastics, clear chips regularly and avoid overheating by using intermittent cutting or lower speeds. After enlarging, inspect the hole for roundness and burrs and, if necessary, perform light deburring or finishing passes.

Usage recommendations

Use appropriate personal protective equipment, clamp workpieces securely, and match speed/feed to the material. Avoid excessive side loads to preserve cutting edge life and maintain straightness of the enlarged hole.
