Value Collection STC1204 T-slot Cutter 1-1/2in Cobalt M42

Product Description

The VALUE COLLECTION STC1204 is a cobalt M42 T-slot cutter designed for milling T-slots in machine tool tables, fixture plates, and other workholding surfaces. The cutter measures 1.5 inches in diameter with a 0.25 inch cutting width and mounts on a 1 inch diameter shank. Overall length is 5.3125 inches. The 8-tooth staggered configuration distributes cutting load evenly, reducing chatter and extending tool life in tough ferrous and stainless materials. Cobalt M42 construction provides heat and wear resistance beyond standard high-speed steel, making this cutter suitable for production runs and interrupted cuts.

This T-slot cutter is intended for use in manual milling machines and CNC machining centers where standard T-slot profiles are required. Typical applications include cutting T-slots for bolt-down fixtures, machine table channels, and similar workholding features in job shops and production machining environments. The 1 inch shank diameter suits standard milling arbors and shell mill holders commonly found in industrial machine shops.

Key Features

• Cobalt M42 grade construction for heat resistance and extended tool life in ferrous materials
• 1.5 inch cutter diameter with 0.25 inch cutting width for standard T-slot profiles
• 8-tooth staggered configuration reduces chatter and distributes cutting forces evenly
• 1 inch shank diameter for compatibility with standard milling arbors
• 5.3125 inch overall length provides reach for typical T-slot depth requirements

Compatibility

Designed as a standard T-slot cutter for use with manual and CNC milling machines equipped with a 1 inch arbor or shell mill holder that accepts T-slot cutter configurations.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Ensure the milling machine spindle is fully powered down and locked out before mounting or removing the cutter from the arbor. Verify arbor runout with a dial indicator before cutting to protect tool life and slot accuracy. Follow applicable shop safety standards and machine manufacturer guidelines for feed rates and depth of cut.
