Value Collection 5-690-010 Convex Radius Cutter Hss

Product Description

The VALUE COLLECTION 5-690-010 is a convex radius cutter designed for milling concave profiles and rounding operations on a variety of workpiece materials. It features a 1/16 inch radius and a 3/4 inch cutter diameter, with a 1/2 inch shank diameter for secure tool holder engagement. Constructed from high speed steel and left uncoated, this cutter delivers reliable performance across general-purpose metalworking applications. The 6-tooth configuration balances chip clearance with surface finish quality, and the Weldon flat on the shank provides positive drive and prevents slippage under cutting loads. Overall length is 3 inches.

This convex radius cutter is suited for manual mills, knee mills, and CNC machining centers in job shop and production environments. It is typically used to cut concave radius slots, profiles, and form features in ferrous and non-ferrous metals, as well as plastics. The shank connection style makes it compatible with standard end mill holders and collet chucks. The Weldon flat allows use with set-screw style tool holders for added holding force during interrupted cuts or heavier feeds.

Key Features

• 1/16 inch convex radius produces a 1/8 inch circle diameter profile in a single pass
• 3/4 inch cutter diameter with 6 teeth for balanced cutting action and surface finish
• High speed steel construction suitable for general-purpose metalworking and non-ferrous materials
• Weldon flat on 1/2 inch shank prevents slippage in set-screw tool holders
• 3 inch overall length provides clearance for most standard mill setups
• Uncoated finish — ready for use as-is or compatible with field-applied lubricants and cutting fluids

Compatibility

Designed as an OEM-style form cutter for use in standard 1/2 inch end mill holders and collet chucks on vertical or horizontal milling machines.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the machine spindle before inserting or removing the cutter. Seat the shank fully into the tool holder and tighten the set screw against the Weldon flat to the tool holder specification before beginning any cut. Inspect the cutting edges for chips or wear before each use, as high speed steel cutters are sensitive to shock loads and interrupted cuts at elevated feeds.
