Value Collection 33050 Cobalt Roughing T-slot Cutter

Product Description

The VALUE COLLECTION 33050 is a cobalt roughing T-slot cutter designed for milling T-slots in metal workpieces on manual and CNC milling machines. Built from M42 cobalt high-speed steel, it delivers increased heat and wear resistance compared to standard M2 HSS tooling, making it well suited for harder ferrous materials and higher-feed roughing passes. The cutter measures 31/32 inches in diameter with a 25/64-inch cutting width and a 3/4-inch shank diameter. It carries 5 straight teeth in an uncoated bright finish. A 17/32-inch neck diameter provides clearance in the slot, and the 1/2-inch bolt size matches standard T-slot hardware for sizing reference.

This cutter is intended for T-slot milling operations in machine shop and toolroom environments, typically used by machinists on knee mills, Bridgeport-style machines, and horizontal milling setups. The roughing geometry removes material aggressively during initial slot passes before a finish cutter is brought in. The 3/4-inch shank fits standard R8, CAT, or side-lock holders commonly found in job shops. Overall length is 3-7/16 inches with a 3-3/64-inch shank length, giving adequate reach for typical T-slot depths.

Key Features

• M42 cobalt HSS construction for improved hot hardness and wear resistance over standard HSS
• Roughing tooth geometry for aggressive material removal on initial T-slot passes
• 5 straight teeth in a bright uncoated finish
• 31/32-inch cutter diameter with 25/64-inch cutting width sized for 1/2-inch bolt T-slots
• 17/32-inch neck diameter provides clearance within the slot during cutting
• 3/4-inch shank diameter fits standard milling machine toolholders

Compatibility

Designed as an OEM-style replacement or standard toolroom cutter for T-slot milling applications requiring a 1/2-inch bolt size slot with a 31/32-inch cutter diameter and 3/4-inch shank.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with milling machine operation and cutting tool safety. Secure the shank firmly in a side-lock or collet holder and verify runout before cutting. Power down and lock out the machine spindle before changing or inspecting the cutter. Follow the machine manufacturer feed and speed recommendations for cobalt HSS tooling in the workpiece material being cut.
