Value Collection 5-693-030 Concave Radius Cutter Hss

Product Description

The VALUE COLLECTION 5-693-030 is a concave radius cutter machined from high speed steel for use in milling operations requiring a precise concave profile. With a 1 inch cut diameter and a 3/16 inch radius, this cutter produces clean, accurate concave grooves and contours on metal workpieces. The 3/4 inch shank with a Weldon flat provides secure tool holding and resists slippage under lateral cutting forces. At 3-1/2 inches overall length and 6 teeth, the cutter balances chip clearance with surface finish. It ships uncoated and is sized for standard horizontal or vertical milling setups used by machinists and tool-and-die professionals.

This concave radius cutter is suited for general metalworking applications including keyway profiling, form milling, and contour work on ferrous and non-ferrous materials. The Weldon flat shank is compatible with standard side-lock tool holders. The 3/16 inch cutting width and 3/8 inch circle diameter make this cutter appropriate for tight-tolerance profile work on production or job-shop milling machines. Machinists working on fixture components, dies, or precision mechanical assemblies will find this cutter fits standard arbor and shank configurations commonly used in those environments.

Key Features

• High speed steel construction for durability across a range of metalworking materials
• Uncoated finish suitable for general-purpose milling without surface treatment concerns
• Weldon flat shank prevents rotational slippage in side-lock tool holders
• 6-tooth design balances material removal rate with surface finish quality
• 3/16 inch radius produces consistent concave profiles in a single pass
• 3-1/2 inch overall length provides clearance for most standard milling setups

Compatibility

Designed as a direct-fit concave radius form cutter for horizontal and vertical milling machines using 3/4 inch shank side-lock or Weldon-style tool holders.

Installation Notes

Installation and operation of this cutter should be performed by qualified machinists familiar with milling machine setup and safe tooling practices. Secure the Weldon flat shank firmly in a matching side-lock holder and verify runout before engaging the workpiece. Power down and lock out the machine before changing or inspecting the cutter. Do not exceed the tool manufacturer's recommended spindle speed for the cutter diameter and material being cut.
