Value Collection 5-690-035 Convex Radius Cutter Hss

Product Description

The VALUE COLLECTION 5-690-035 is a convex radius cutter designed for milling concave profiles and contoured surfaces on metal workpieces. Built from high-speed steel (HSS) with an uncoated finish, this cutter produces a 0.25-inch radius profile with a 0.5-inch circle diameter and a 1.5-inch cutter diameter. It runs on a shank connection with a 0.75-inch shank diameter and includes a Weldon flat for positive drive and reduced slippage in the holder. With 6 teeth and a 4-inch overall length (OAL), it suits shops and toolrooms where accurate radius profiling is required. Machinists and tool-and-die professionals are the primary installers.

This convex radius cutter is suited for milling operations on ferrous and non-ferrous metals in manual knee mills, CNC vertical machining centers, and horizontal milling setups. It is appropriate for both job shop and production environments where consistent concave radius features must be machined into workpiece edges, slots, or pockets. The Weldon flat shank is compatible with standard side-lock end mill holders.

Key Features

• 0.25-inch radius profile with 0.5-inch circle diameter for precise concave contour milling
• 1.5-inch cutter diameter provides broad engagement for efficient material removal
• High-speed steel construction offers toughness and re-sharpenability
• Uncoated finish allows easy re-grinding without coating adhesion concerns
• Weldon flat shank provides positive drive and resists axial pullout
• 6-tooth design balances chip load and surface finish on profiling cuts

Compatibility

Designed as an OEM-style replacement or direct-use convex radius cutter for standard side-lock Weldon-flat end mill holders accepting a 0.75-inch shank diameter.

Installation Notes

Installation is performed by machinists or toolroom professionals. Power down and lock out the machine spindle before mounting or removing the cutter. Seat the shank fully into the holder and tighten the side-lock set screw against the Weldon flat to the holder manufacturer's specification. Inspect the cutter for chips or edge damage before each use and confirm runout with a dial indicator when precision profiling is required.
