Value Collection 5-690-030 Convex Radius Cutter Hss

Product Description

The VALUE COLLECTION 5-690-030 is a convex radius cutter designed for milling convex radii and rounded profiles on metal workpieces. It features a 3/16 inch radius with a 1-3/8 inch cutter diameter and a 3/8 inch circle diameter, making it well suited for precision contour work on ferrous and non-ferrous materials. Constructed from high speed steel with an uncoated finish, it delivers reliable performance across general-purpose machining applications. The 3/4 inch shank with a Weldon flat provides positive engagement in the tool holder, reducing slippage under cutting loads. With 6 teeth and a 3-1/2 inch overall length, this cutter is a standard choice for machinists and tool-and-die professionals running manual or CNC milling operations.

This convex radius cutter is appropriate for use on vertical and horizontal milling machines in job shops, manufacturing facilities, and maintenance machining environments. It is suited for producing rounded grooves, convex profiles, and contoured edges on steel, cast iron, aluminum, and similar machinable materials. The Weldon flat shank is compatible with standard end mill holders equipped for set-screw retention, which is common in both manual and CNC mill setups. This tool is typically installed and operated by machinists, tool-and-die makers, and precision metalworking professionals.

Key Features

• 3/16 inch radius for accurate convex profile milling
• 1-3/8 inch cutter diameter with 6 teeth for consistent chip load
• High speed steel construction for general-purpose metal cutting
• Weldon flat on 3/4 inch shank for secure set-screw retention
• 3-1/2 inch overall length for standard milling machine reach
• Uncoated finish suitable for a wide range of machinable materials

Compatibility

Designed as a standard shank-type convex radius cutter compatible with milling machine tool holders accepting a 3/4 inch Weldon flat shank with set-screw retention.

Installation Notes

Installation and operation should be performed by a qualified machinist familiar with milling machine tooling and safe cutting practices. Power down and lock out the machine before inserting or removing the cutter from the tool holder. Secure the Weldon flat set screw to proper engagement before beginning any cut. Inspect the cutter for chipping or wear before each use and replace if edge integrity is compromised.
