Value Collection 12505 Convex Radius Cutter Arbor

Product Description

The VALUE COLLECTION 12505 is a convex radius cutter designed for milling concave profiles and contoured surfaces on metal workpieces. Constructed from high speed steel (HSS) with a form relieved profile and uncoated finish, this cutter delivers consistent cutting geometry across its 12 teeth. It accepts an arbor connection with a 1-inch arbor hole diameter and measures 2.25 inches in overall cutter diameter. The 1/16-inch radius produces a 1/8-inch full circle diameter on the finished surface. Machinists and tool-and-die professionals use this cutter on horizontal milling machines for precision form work in production and job-shop environments.

This convex radius cutter is suited for milling concave radius grooves, rounding interior edges, and generating matched radius profiles in ferrous and non-ferrous metals. Its form relieved tooth geometry maintains accurate profile shape through repeated sharpenings, making it a practical choice for shops that regrind their tooling. The uncoated HSS construction is appropriate for conventional cutting speeds and standard cutting fluid applications typical in general-purpose machine shops.

Key Features

• High speed steel construction for durability in metal milling applications
• Form relieved relief style preserves cutter profile geometry through repeated resharpening
• 12 teeth provide balanced chip load and surface finish quality
• 1/16-inch convex radius generates a precise 1/8-inch circle diameter profile
• 1-inch arbor hole diameter for standard horizontal milling machine arbor mounting
• Uncoated finish compatible with a wide range of cutting fluids and workpiece materials

Compatibility

Designed as an OEM-style replacement or standard production cutter for horizontal milling machines accepting a 1-inch arbor and requiring a convex radius form cutter.

Installation Notes

Installation is performed by qualified machinists on horizontal milling machines. Power down and lock out the machine before mounting or removing the cutter from the arbor. Ensure the arbor, spacers, and cutter bore are clean and free of burrs before assembly, and confirm the draw bolt or arbor nut is properly torqued per the machine manufacturer specification. Use appropriate cutting fluid for the workpiece material to maximize tool life and surface finish quality.
