Value Collection STC0803 T-slot Cutter 1 in Cobalt M42

Product Description

The VALUE COLLECTION STC0803 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, this cutter handles the demanding lateral and radial forces that T-slot milling generates. It measures 1 inch in diameter with a 3/16 inch cutting width and mounts on a 5/8 inch shank. The 8-tooth staggered configuration distributes the cutting load evenly, reducing chatter and improving chip evacuation in ferrous and non-ferrous materials. Overall length is 4-15/16 inches. This cutter is used by machinists and tool-and-die professionals on manual or CNC vertical milling machines.

This T-slot cutter is suited for cutting standard T-slots in steel, cast iron, aluminum, and similar materials on knee mills, bed mills, and machining centers. It is most commonly used in job shops, maintenance facilities, and manufacturing environments where T-slotted tables, T-nut tracks, and fixture bases require precise slot profiles. The staggered tooth design makes it well-matched for moderate-depth passes in both conventional and climb milling operations.

Key Features

• M42 cobalt high-speed steel construction for heat and wear resistance in tough materials
• 1 inch cutter diameter with 3/16 inch cutting width for standard T-slot profiles
• 5/8 inch shank diameter for secure arbor or collet mounting
• 8-tooth staggered configuration reduces cutting forces and improves chip flow
• 4-15/16 inch overall length provides clearance for typical T-slot depth applications

Compatibility

Designed as a standard T-slot cutter for use on vertical milling machines and machining centers accepting a 5/8 inch shank arbor or collet holder.

Installation Notes

T-slot cutters are installed by qualified machinists on milling machines rated for the required spindle speeds and cutting loads. Secure the shank in a properly sized arbor or collet and confirm runout before engaging the cut. Always power down the machine and lock out energy before changing or inspecting the cutter. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life and maintain dimensional accuracy.
