Cleveland C32880 Square End Mill 0.125 in 2 Flute Cobalt

Product Description

The CLEVELAND C32880 is a cobalt square end mill designed for high-performance metal removal in demanding machining applications. Built from M42 cobalt high-speed steel and finished with a TiCN coating, this double-end tool delivers extended tool life when cutting stainless steel, high-temperature alloys, and carbon steel. It features a 0.125 inch (1/8 inch) mill diameter, a 0.375 inch length of cut, and a 0.375 inch straight cylindrical shank with a Weldon flat option. The spiral flute geometry and 30-degree helix angle promote efficient chip evacuation. Installed by machinists and tool-and-die professionals, it fits standard milling machines, CNC machining centers, and knee mills.

The C32880 belongs to Cleveland's HDC-2 series, a line engineered for cutting high-temperature alloys, stainless steels, and steels in production and job-shop environments. The double-end configuration extends tool value by providing two usable cutting ends. With a 3-1/16 inch overall length and a regular-length classification, it suits typical reach requirements in vertical and horizontal milling setups. Centercutting capability allows for plunge milling as well as conventional peripheral and slot milling operations.

Key Features

• M42 cobalt construction for elevated heat and wear resistance vs. standard HSS
• TiCN finish reduces friction and extends tool life in ferrous materials
• Double-end design provides two cutting ends per tool
• 30-degree helix angle with spiral flutes for efficient chip evacuation
• Centercutting geometry allows direct plunge entry
• Right-hand cut and right-hand flute configuration; compatible with standard spindle rotation

Compatibility

Designed for use on conventional and CNC milling machines accepting a 0.375 inch straight-cylindrical or Weldon flat shank. Primary workpiece materials include high-temperature alloys, stainless steel, and steel (material codes S, M, P).

Installation Notes

This end mill is installed by machinists using a collet, end mill holder, or Weldon-style set-screw holder rated for the 0.375 inch shank diameter. Confirm holder runout is within acceptable limits before use, as excess runout accelerates edge wear on small-diameter tools. Power down and lock out the spindle before changing tooling. Follow shop-specific speeds and feeds for cobalt end mills in the target material.
