Cleveland C32546 Square End Mill 7/16 in 2 Flute Cobalt

Product Description

The CLEVELAND C32546 is a cobalt square end mill designed for metal removal in demanding machining operations. Built from M42 cobalt high-speed steel and finished with a TiCN coating, this single-end mill delivers improved hardness and heat resistance compared to standard HSS tooling. It features a 7/16 inch cutting diameter, a 13/16 inch length of cut, and a 2-flute spiral configuration with a 30-degree helix angle. The centercutting geometry allows plunge entry. This tool is sized for use in manual mills and CNC machining centers and is typically installed by machinists and tool-and-die professionals working with ferrous and high-temp alloy workpieces.

The C32546 is suited for milling operations on steel, stainless steel, and high-temperature alloys. Its 3/8 inch straight-cylindrical shank with Weldon flat accepts standard end mill holders and set-screw-style toolholders. The right-hand cut and right-hand flute direction make it compatible with conventional spindle rotation on standard vertical and horizontal milling setups. The HGC-2 series geometry is intended for production work in materials that generate significant heat at the cutting edge.

Key Features

• M42 cobalt construction for elevated red hardness and wear resistance in ferrous materials
• TiCN coating reduces friction and extends tool life compared to uncoated cobalt
• Centercutting design allows direct plunge milling without a pre-drilled entry point
• 30-degree helix angle promotes smooth chip evacuation and reduces chatter
• Weldon flat on shank provides positive drive and resists pullout in heavy cuts
• Right-hand cut, right-hand flute — compatible with standard spindle rotation

Compatibility

Designed for use with standard 3/8 inch end mill holders and Weldon-style set-screw toolholders. Primary workpiece materials include high-temperature alloys, stainless steel, and steel (material codes M, P, S).

Installation Notes

Installation is performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully in the holder and align the Weldon flat with the set screw before tightening. Verify runout with a dial indicator before beginning a cut, and confirm feeds and speeds are appropriate for the workpiece material and machine rigidity.
