Value Collection 316-1247 Concave Radius Cutter

Product Description

The VALUE COLLECTION 316-1247 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 form-relieved cutter produces a consistent 11/16-inch radius in a single pass. The 4-1/4-inch cut diameter and 1-3/8-inch cut width allow material removal across a broad face, while the 1-1/4-inch arbor bore provides solid mounting on standard horizontal milling arbors. With 10 teeth, the cutter delivers a balance of chip clearance and surface finish suited to production and toolroom work.

This cutter is used in horizontal milling machine setups where a precise concave radius form must be machined into steel, cast iron, or similar ferrous materials. Typical applications include cutting grooves, radii on shafts, and form profiles in die and mold work, as well as general toolroom operations. The form-relieved geometry maintains the correct profile as the cutter is resharpened, extending usable tool life in repeated-production environments.

Key Features

• High speed steel construction for cutting ferrous and non-ferrous metals
• Oxide finish for corrosion resistance and reduced friction at the cutting edge
• Form-relieved profile maintains radius accuracy through multiple resharpenings
• 10 teeth provide balanced chip load and smooth surface finish
• 1-1/4-inch arbor bore fits standard horizontal milling machine arbors
• 1-3/8-inch circle diameter and 1-3/8-inch cut width for defined profile geometry

Compatibility

Designed for use on horizontal milling machines equipped with a standard 1-1/4-inch arbor. Suitable for toolroom, die, and production milling applications requiring a concave radius profile.

Installation Notes

Installation is performed by a machinist or toolroom professional on a horizontal milling machine. Power down and lock out the machine before mounting or removing the cutter from the arbor. Secure the arbor nut to the manufacturer-specified procedure and verify cutter runout before beginning a cut. Always use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.
