Cleveland C32908 Square End Mill 3/4 in 2 Flute Cobalt

Product Description

The CLEVELAND C32908 is a double-end cobalt square end mill designed for milling operations in ferrous and difficult-to-machine materials. Built from M42 cobalt high-speed steel, it carries a TiCN (titanium carbonitride) coating that extends tool life by reducing heat and wear at the cutting edge. The 3/4 inch diameter cutter features two spiral flutes at a 30-degree helix angle, delivering efficient chip evacuation and smooth cutting action. At 5.625 inches overall length with a 1.3125 inch length of cut, it suits a range of standard milling setups on manual and CNC knee mills, bed mills, and machining centers. Centercutting geometry allows plunge entry directly into the workpiece without a pre-drilled pilot hole.

The C32908 is suited for peripheral milling, slotting, and plunge milling in steel, stainless steel, cast iron, and high-temperature alloys where tool hardness and heat resistance are critical. The double-end configuration provides two usable cutting ends, extending tool value on production and job-shop floors. Right-hand cut and right-hand flute orientation match conventional spindle direction on standard vertical milling machines. This tool is part of the CLEVELAND HDC-2 series, engineered for heavy-duty cutting applications where standard HSS tooling is insufficient.

Key Features

• M42 cobalt high-speed steel construction for superior heat and wear resistance
• TiCN coating reduces friction and extends cutting edge life in demanding materials
• Double-end design provides two cutting ends per tool
• Centercutting geometry enables direct plunge entry without pilot hole
• 30-degree helix angle promotes efficient chip evacuation and smooth cutting
• Right-hand cut and right-hand flute for standard spindle compatibility

Compatibility

Designed as an OEM-style replacement and standard tooling option for vertical milling machines, knee mills, and CNC machining centers accepting a 3/4 inch straight shank end mill holder or collet. Part of the CLEVELAND HDC-2 series.

Installation Notes

Installation is performed by a machinist or toolroom technician using an appropriate end mill holder or collet sized for a 3/4 inch shank. Ensure the machine spindle is fully stopped and the power is locked out before changing tooling. Inspect the tool holder for runout before seating the end mill, as excessive runout accelerates edge wear and reduces surface finish quality. Follow shop-standard tool-change procedures and machine manufacturer guidelines for clamping torque and projection length.
