Value Collection STC0808 T-slot Cutter 1 in Cobalt M42

Product Description

The VALUE COLLECTION STC0808 is a cobalt T-slot cutter designed for milling T-slots in machine tables, fixtures, and workholding components. Built from M42 cobalt high-speed steel, it delivers increased heat and wear resistance compared to standard HSS tooling, making it suitable for harder materials and higher cutting speeds. The cutter measures 1 inch in diameter with a 1/2 inch cutting width and runs on a 5/8 inch shank. An 8-tooth staggered configuration promotes chip evacuation and reduces cutting forces, which helps maintain surface finish quality in production milling environments. Overall length is 4-15/16 inches.

This T-slot cutter is used in manual and CNC milling machines to produce T-slot profiles that accept T-nuts and hold-down bolts. Typical applications include machining of steel, cast iron, and aluminum workholding plates, machine tool tables, and fixture bases. The staggered tooth geometry makes it well suited for both roughing passes and finishing cuts in a single tool. Machinists and toolroom operators in job shops, maintenance facilities, and production machine shops are the primary users of this cutter.

Key Features

• M42 cobalt HSS construction for improved heat resistance and tool life over standard M2 HSS
• 1 inch cutter diameter with 1/2 inch cutting width for standard T-slot profiles
• 8-tooth staggered configuration promotes chip clearance and reduces chatter
• 5/8 inch shank diameter for secure arbor or collet mounting on standard milling machines
• 4-15/16 inch overall length provides reach for typical T-slot depths

Compatibility

Designed as an OEM-style replacement or direct tooling option for milling machines accepting 5/8 inch shank T-slot cutters with standard arbor or collet toolholding systems.

Installation Notes

Installation is performed by a machinist or toolroom technician. Secure the 5/8 inch shank in a properly sized collet, end mill holder, or arbor on a manual or CNC milling machine before commencing any cut. Ensure the spindle is fully stopped and locked before mounting or removing the cutter. Follow the machine manufacturer and tooling supplier recommendations for spindle speed and feed rate based on workpiece material — do not exceed the cutter or machine spindle rated limits.
