Value Collection 33038 T-slot Cutter 9/16 in Cobalt M42

Product Description

The VALUE COLLECTION 33038 is a cobalt M42 T-slot cutter designed for milling T-slots in machine tables, fixtures, and workholding components. The cutter measures 9/16 inches in diameter with a 15/64 inch cutting width and mounts on a 1/2 inch straight shank. Eight straight teeth provide clean, consistent slot profiles in ferrous and non-ferrous metals. The bright uncoated finish is standard for general-purpose T-slot work where coating is not required. Machinists and tool-and-die professionals install this cutter in vertical milling machines and machining centers when cutting standard T-slot profiles to accept 1/4 inch bolts.

This T-slot cutter is suited for job shops, maintenance machining, and fixture fabrication where 1/4 inch bolt-size T-slots are required. The M42 cobalt grade provides improved heat and wear resistance compared to standard M2 high-speed steel, making it a practical choice for harder workpiece materials or applications where longer tool life between changes is a priority. The compact neck geometry at 0.2656 inches diameter and 35/64 inch neck length provides the necessary clearance for full-depth slot engagement.

Key Features

• Cobalt M42 grade construction for improved heat resistance and tool life versus standard HSS
• 8 straight teeth for consistent T-slot profile cutting
• 9/16 inch cutter diameter with 15/64 inch cutting width for 1/4 inch bolt-size T-slots
• 0.2656 inch neck diameter and 35/64 inch neck length provide clearance for full slot depth
• 1/2 inch shank diameter for standard milling machine and machining center collets or holders
• Bright uncoated finish suitable for general-purpose ferrous and non-ferrous milling applications

Compatibility

Designed as a standard T-slot cutter for use in vertical milling machines and machining centers accepting a 1/2 inch shank, for cutting T-slots sized for 1/4 inch bolts.

Installation Notes

Installation is performed by machinists in a milling machine or machining center with the spindle fully powered down and the machine in a safe lockout state before tool changes. Secure the 1/2 inch shank in an appropriate collet or end mill holder and verify runout before cutting. Always rough the T-slot undercut in multiple passes at appropriate feed and speed for the workpiece material rather than attempting full-depth engagement in a single pass. Follow shop safety procedures and machine manufacturer guidelines for cutter installation and operation.
