Value Collection 317-0412 Convex Radius Cutter Hss Arbor

Product Description

The VALUE COLLECTION 317-0412 is a convex radius cutter designed for milling convex radii and contoured profiles on metal workpieces. Built from high speed steel (HSS), this form-relieved cutter maintains its profile geometry through repeated sharpenings, making it a practical choice for production and toolroom environments. It carries a 5/16-inch radius, a 3-1/2-inch outer diameter, and 12 teeth. The bright finish indicates an uncoated HSS tool, suited for general-purpose milling operations. It mounts via arbor connection and is installed by machinists and tool-and-die professionals on horizontal milling machines.

This cutter is used in metalworking applications where a consistent convex radius must be machined into a part. Typical scenarios include die work, mold making, and precision part manufacturing in both job shop and production settings. The form-relieved relief style ensures the cutter profile is preserved when the tool is resharpened by grinding the face, not the flank, which extends usable tool life without altering the radius geometry.

Key Features

• 5/16-inch convex radius for consistent profile milling
• 3-1/2-inch outer diameter for standard horizontal arbor mill setups
• 12-tooth configuration balances chip clearance and surface finish
• High speed steel construction withstands heat generated in ferrous and non-ferrous milling
• Form-relieved relief style preserves cutter profile through face-grinding resharpening
• Bright finish — uncoated HSS suitable for general-purpose milling applications

Compatibility

Designed as an OEM-style arbor-mount convex radius cutter for use on horizontal milling machines accepting standard milling arbors.

Installation Notes

Installation is performed by a qualified machinist. Power down and lock out the milling machine before mounting or removing the cutter. Secure the cutter firmly on the milling arbor with the appropriate spacers and arbor nut before operation. Inspect the cutter for chips or cracks before each use and do not operate a damaged tool.
