Value Collection 317-0446 Convex Radius Cutter Hss 12T

Product Description

The VALUE COLLECTION 317-0446 is a convex radius cutter designed for milling operations that require a precise, concave profile in the workpiece. With an 11/32-inch radius and a 3-inch cutter diameter, this form-relieved tool produces consistent, repeatable radii in a single pass. It features 12 teeth and mounts via a standard arbor connection. Manufactured from high speed steel (HSS), it delivers adequate hardness and wear resistance for cutting ferrous and non-ferrous metals, plastics, and composite materials. The bright finish reduces friction at the cutting edge. Machinists, tool-and-die makers, and CNC mill operators use this style of cutter for form milling, slotting, and profile work.

This convex radius cutter is suited for use on horizontal milling machines with a standard arbor setup. It applies to general-purpose form milling in job shops, maintenance machine shops, and production environments. Typical applications include generating rounded grooves, concave seat profiles, and contoured reliefs in metal components. The 3-inch diameter and 12-tooth configuration support moderate feed rates and deliver a clean surface finish on most common workpiece materials encountered in trade and industrial settings.

Key Features

• 11/32-inch convex radius for precise concave profile milling in a single pass
• 3-inch cutter diameter compatible with standard horizontal arbor milling setups
• 12 teeth provide a balance of feed rate capacity and surface finish quality
• High speed steel construction offers hardness and toughness across a wide range of workpiece materials
• Form-relieved relief geometry maintains profile accuracy as the cutter is resharpened
• Bright finish reduces friction and built-up edge at the cutting zone

Compatibility

Designed as a standard arbor-mount convex radius cutter for use on horizontal milling machines accepting arbor-style tooling of the appropriate bore size.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the milling machine before mounting or removing the cutter from the arbor. Ensure the arbor bore, spacers, and retaining nut are clean and free of chips before seating the cutter. Verify spindle speed and feed rate are set to values appropriate for the workpiece material and cutter diameter before beginning a cut.
