Value Collection 33030 3/4 in Cobalt End Mill 3 Flute

Product Description

The VALUE COLLECTION 33030 is a roughing finishing end mill designed for aggressive material removal and finish-quality cuts in a single tool. Machined from M42 cobalt high-speed steel, it offers superior heat and wear resistance compared to standard HSS tooling. The 3/4 inch diameter, 3-flute geometry with a 45-degree helix angle promotes efficient chip evacuation and reduces chatter during both roughing and semi-finishing passes. The bright uncoated finish makes it well suited for use with cutting fluids in ferrous and non-ferrous applications. Weighing 0.5 pounds, it is built for daily production use on manual mills and CNC machining centers alike.

This end mill is used in job shops, tool rooms, and production machining environments where operators need to rough and finish in fewer passes. The square end profile handles shoulder milling, slotting, and peripheral milling. With a 3 inch length of cut and 5-1/4 inch overall length, it reaches workpiece features requiring extended engagement without sacrificing rigidity. The straight 3/4 inch shank seats directly in standard collets, end mill holders, or Weldon-style holders. It is a single-end tool intended for right-hand cutting with right-hand flute direction.

Key Features

• M42 cobalt HSS construction for improved heat resistance and edge retention over standard M2 HSS
• 45-degree helix angle promotes smooth chip flow and reduces cutting forces
• 3-flute design balances chip clearance with core strength for combined roughing and finishing
• Center-cutting capable — allows plunge entry directly into the workpiece
• Bright uncoated finish compatible with most cutting oils and water-soluble coolants
• Square end profile suits shoulder milling, slotting, and step cutting

Compatibility

Designed as an OEM-style replacement or direct-use end mill for standard 3/4 inch collet chucks, end mill holders, and Weldon-style tool holders on manual knee mills and CNC vertical machining centers.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight shank fully into the holder and tighten to the holder manufacturer's specified clamping torque using calibrated tooling. Inspect the cutting edges for chips or burrs before the first pass, and confirm runout with a dial indicator when tight tolerances are required.
