Value Collection 316-0488 Concave Radius Cutter Hss

Product Description

The VALUE COLLECTION 316-0488 is a concave radius cutter designed for milling concave profiles and radii on metal workpieces. Built from high speed steel with an oxide finish, this arbor-mounted cutter produces a 3/8 inch radius in a single pass. The 3 inch cutter diameter and 10-tooth form-relieved design provide consistent chip clearance and profile accuracy. It mounts on a 1 inch arbor and is suited for use on manual milling machines and CNC horizontal mills. Machinists and tool-and-die professionals use this type of cutter for radius form milling on steel, aluminum, and similar metals where a precise concave contour is required.

This cutter is appropriate for horizontal milling setups in job shops, maintenance and repair operations, and production environments requiring repeatable concave radius profiles. The form-relieved relief style allows the cutter to be resharpened on the face without altering the tooth profile geometry, extending useful tool life. The 0.75 inch circle diameter and 3 inch cut diameter make this a mid-size cutter suitable for general-purpose radius milling on a range of part sizes.

Key Features

• 3/8 inch concave radius for single-pass profile milling
• High speed steel construction for durability across common metal types
• Oxide finish provides basic corrosion resistance and reduces friction during cutting
• Form-relieved teeth allow face resharpening without changing profile geometry
• 10-tooth configuration balances chip clearance with surface finish quality
• 1 inch arbor hole fits standard horizontal milling machine arbors

Compatibility

Designed as a standard arbor-mount concave radius cutter compatible with horizontal milling machines fitted with a 1 inch milling arbor.

Installation Notes

Installation is performed by qualified machinists on horizontal milling equipment. Power down and lock out the machine before mounting or removing the cutter. Ensure the arbor, spacers, and arbor nut are clean and free of burrs before seating the cutter. Follow the machine manufacturer torque guidance for arbor nut tightening and verify cutter runout before beginning the cut.
