Value Collection STC2012 Cobalt T-slot Cutter 2.5 in

Product Description

The VALUE COLLECTION STC2012 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 tough materials and interrupted cuts that would dull standard HSS tooling faster. It measures 2.5 inches in diameter with a 0.75-inch cutting width and mounts on a 1-inch shank. The 12-tooth staggered configuration alternates cutting edges to reduce chatter and improve chip evacuation during the finishing pass of a T-slot operation. Machinists and tool-and-die technicians working on manual mills or CNC machining centers are the primary users of this tool.

This cutter is used in machine shop environments for cutting the undercut portion of T-slots in steel, cast iron, aluminum, and similar workpiece materials. The T-slot operation typically follows a vertical slot cut with an end mill, and this tool completes the horizontal undercut that accepts T-nuts and hold-down bolts. Its 6.625-inch overall length provides adequate clearance for reaching into workpieces without interference from the spindle nose or holder body. Suitable for both production and maintenance machine shop applications.

Key Features

• M42 cobalt HSS construction provides higher heat and wear resistance than standard M2 HSS cutters
• Staggered tooth configuration reduces cutting forces and minimizes chatter on the undercut pass
• 12 teeth deliver a balance of feed rate capability and finish quality
• 1-inch shank diameter fits standard milling arbors and side-lock holders
• 2.5-inch cutter diameter and 0.75-inch width suit common T-slot standards found on machine tables and fixtures
• 6.625-inch overall length provides reach clearance for typical milling setups

Compatibility

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

Installation Notes

Installation of this cutter is performed by a qualified machinist. Secure the 1-inch shank in a properly sized arbor or side-lock holder and confirm runout before cutting. Always complete the preliminary vertical slot with an end mill before engaging this T-slot cutter on the undercut pass. Reduce spindle speed and feed rate compared to standard end milling to account for the interrupted cut geometry and extended tool engagement.
