Value Collection 317-0651 Convex Radius Cutter Hss 12T

Product Description

The VALUE COLLECTION 317-0651 is a convex radius cutter designed for milling convex profiles and rounding operations on metalworking mills. Built from high speed steel (HSS) with a bright finish, this form-relieved cutter generates a 1/2 inch radius profile in a single pass. It mounts via a standard arbor connection, fitting horizontal and universal milling machine setups. With 12 teeth and a 4-1/4 inch outer diameter, it delivers smooth chip flow and consistent surface finish on ferrous and non-ferrous workpieces. Licensed machinists and tool room operators are the primary users of this style of cutter.

This cutter is suited for horizontal milling applications in job shops, tool rooms, and production environments. It is used wherever a precise convex radius must be machined into a workpiece, such as forming grooves, rounding external profiles, or producing mating concave features. Its form-relieved relief style maintains accurate tooth geometry even after resharpening, extending usable tool life across multiple regrinds. Single-piece packaging makes it appropriate for both shop-stock replenishment and individual project procurement.

Key Features

• 1/2 inch convex radius profile milled in a single pass
• High speed steel construction for durability on ferrous and non-ferrous materials
• Form-relieved relief style preserves tooth profile geometry through resharpening
• Bright finish resists surface oxidation during storage and use
• 12 teeth for consistent chip load and smooth surface finish
• Standard arbor connection compatible with horizontal milling machine arbors

Compatibility

Designed as an OEM-style form cutter for use on horizontal and universal milling machines equipped with a standard arbor drive system.

Installation Notes

Installation is performed by a qualified machinist on a powered-off and locked-out milling machine. Mount the cutter securely on the arbor with appropriate spacers and the arbor nut torqued per machine specifications before powering the spindle. Inspect the arbor bore and cutter bore for debris or damage before seating. Always use appropriate cutting fluid and verify spindle speed is within the recommended range for the workpiece material and cutter diameter before engaging the cut.
