Value Collection STC1604 T-slot Cutter 2in Cobalt M42

Product Description

The VALUE COLLECTION STC1604 is a cobalt M42 T-slot cutter designed for milling T-slots in machine tables, fixtures, and workholding components. With a 2-inch cutter diameter and a 1/4-inch cutting width, it removes material in a single pass to produce clean, accurate T-slot profiles. The staggered tooth configuration across 10 teeth reduces cutting forces and helps evacuate chips efficiently. A 1-inch shank diameter provides rigid tool holding in standard milling chucks and holders. Overall length is 5-11/16 inches. This cutter is suited for use in vertical milling machines and machining centers where T-slots must be cut to accept bolts, clamps, or fixture hardware.

This T-slot cutter is used in machine shops, toolrooms, and manufacturing facilities for cutting T-slots in cast iron, steel, aluminum, and other ferrous and non-ferrous workpieces. It is appropriate for both manual knee mills and CNC machining centers. Typical applications include producing T-slots in vise bases, angle plates, milling machine tables, and custom fixture plates. The M42 cobalt grade provides elevated heat resistance compared to standard high-speed steel, making it suitable for harder workpiece materials and higher cutting speeds.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS
• Staggered tooth geometry across 10 teeth for reduced cutting forces and better chip flow
• 2-inch cutter diameter with 1/4-inch cutting width for standard T-slot profiles
• 1-inch shank diameter fits standard milling chucks and CAT or R8 holders with appropriate collet
• 5-11/16-inch overall length provides clearance for most table and fixture applications

Compatibility

Designed as an OEM-style replacement or direct-use T-slot cutter for manual and CNC milling machines accepting a 1-inch shank diameter tool holder.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician. Ensure the milling machine spindle is fully stopped and the machine is powered down before loading or changing the cutter. Confirm the shank is fully seated and the holder drawbar or set screws are properly tightened before initiating a cut. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.
