Value Collection 12477 Concave Radius Cutter 1/16 in Hss

Product Description

The VALUE COLLECTION 12477 is a concave radius cutter designed for milling precise concave profiles and grooves in metalworking applications. Built from high speed steel (HSS) with an uncoated finish, this cutter delivers consistent performance on a variety of ferrous and non-ferrous materials. It features a 1/16 inch radius, a 3/4 inch cut diameter, and a 0.26 inch cut width, making it well suited for generating accurate radius forms in a single pass. The form-relieved tooth design maintains the cutter profile through repeated sharpenings, extending usable tool life. A Weldon flat on the 1/2 inch shank provides a secure, slip-resistant connection in standard end mill holders.

This cutter is used in manual and CNC milling operations where a precise concave radius profile is required. Typical applications include producing rounded grooves, decorative profiles, and mating concave forms on shafts, dies, and machine components. The 3 inch overall length and 1/2 inch shank diameter suit standard vertical milling machines and machining centers equipped with R8, CAT, or BT tooling using an appropriate end mill holder. It is installed and operated by machinists, tool and die makers, and maintenance technicians working in fabrication and production environments.

Key Features

• 1/16 inch radius profile for accurate concave milling in a single pass
• High speed steel construction provides toughness and wear resistance across common workpiece materials
• Form-relieved tooth geometry maintains cutter profile geometry through repeated resharpening
• Weldon flat on 1/2 inch shank prevents slipping in standard end mill holders
• 6-tooth configuration balances chip clearance with surface finish quality
• Uncoated finish for use with standard cutting fluids on ferrous and non-ferrous materials

Compatibility

Designed as a standard-shank concave radius cutter compatible with milling machines and machining centers that accept a 1/2 inch diameter Weldon-flat end mill holder.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the machine spindle is fully powered down and locked out before loading or changing tooling. Secure the Weldon flat shank in a properly sized end mill holder, tightening the set screw firmly against the flat to prevent axial pullout during cutting. Always verify correct spindle speed and feed rate for the workpiece material before engaging the cut.
