Value Collection 12451 Convex Radius Cutter Hss

Product Description

The VALUE COLLECTION 12451 is a convex radius cutter designed for milling concave profiles on ferrous and non-ferrous workpieces. It carries a 1/32-inch radius and a 3/4-inch cutter diameter, producing a 1/16-inch circle diameter profile. The cutter is manufactured from high-speed steel (HSS) with an uncoated finish and a form-relieved tooth geometry. Six teeth deliver smooth chip evacuation and consistent surface finish. A 1/2-inch shank diameter with a Weldon flat provides positive drive engagement and resists slippage in standard end mill holders. Overall length is 3 inches. This tool is installed by machinists and toolroom technicians on manual or CNC milling machines.

The 12451 convex radius cutter is suited to general-purpose milling applications requiring precise concave radius forms. Typical use cases include cutting decorative molding profiles, tool and die work, and radius blending operations on steel, cast iron, aluminum, and similar machinable materials. The uncoated HSS construction makes it appropriate for lower-speed operations and applications where regrinding is preferred over coated tooling. Form-relieved geometry maintains the correct profile through successive resharpenings on the rake face.

Key Features

• 1/32-inch convex radius produces a precise 1/16-inch circle diameter profile
• 3/4-inch cutter diameter with 6 form-relieved teeth for consistent profile accuracy
• High-speed steel construction supports regrindable service life
• Uncoated finish suits general-purpose and lower-speed milling applications
• 1/2-inch shank with Weldon flat for positive, slip-resistant drive in standard holders
• 3-inch overall length provides clearance for standard milling setups

Compatibility

Designed for use in standard milling machine spindles and CNC machining centers accepting a 1/2-inch shank end mill holder or collet with Weldon flat drive capability.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the Weldon flat against the set screw in the holder before tightening to the torque specified by the holder manufacturer. Confirm spindle speed and feed rate are appropriate for the workpiece material and cutter diameter before beginning the cut. Inspect the cutter profile for wear or chipping before each use and replace or regrind when profile accuracy degrades.
