Value Collection 316-1320 Concave Radius Cutter

Product Description

The VALUE COLLECTION 316-1320 is a concave radius cutter designed for milling concave profiles and grooves on metal workpieces. Manufactured from high speed steel with an oxide finish, this form-relieved cutter delivers consistent profile geometry across each pass. It features a 3/4-inch radius, a 4-1/4-inch cut diameter, and a 1-1/4-inch arbor bore, making it compatible with standard horizontal milling arbors. With 10 teeth and a form-relieved tooth profile, the cutter maintains accuracy through resharpening without altering the cutting form. It is suited for production and toolroom environments where precise concave contours are required.

This cutter is applied in horizontal milling operations where a consistent concave radius profile must be machined into steel, cast iron, or similar materials. Typical applications include producing rounded grooves, concave seats, and profile features on shafts, fixtures, and mechanical components. The 1-1/2-inch circle diameter and 1-1/2-inch cut width define the depth and breadth of the cut zone, making this tool suitable for moderate-width profiling passes in both job shop and production settings.

Key Features

• High speed steel construction for durability in ferrous and non-ferrous milling applications
• Oxide finish for corrosion resistance and reduced chip adhesion
• Form-relieved tooth profile preserves cutter geometry through multiple resharpenings
• 10 teeth provide a balance of chip clearance and surface finish quality
• 3/4-inch radius produces a consistent concave contour in a single pass
• 1-1/4-inch arbor bore fits standard horizontal milling machine arbors

Compatibility

Designed for use on horizontal milling machines equipped with a 1-1/4-inch arbor. Suitable as a form cutter for concave radius profiling operations across a range of metalworking applications.

Installation Notes

Installation and operation should be performed by a qualified machinist. Power down and lock out the milling machine before mounting or removing the cutter from the arbor. Ensure the arbor, spacers, and arbor nut are clean and properly torqued per the machine manufacturer specifications before engaging the cut. Inspect the cutter for chips, cracks, or dull teeth before each use and do not operate a damaged cutter.
