Cleveland C41268 Square End Mill 7/8 in 4 Flute Hss

Product Description

The CLEVELAND C41268 is a 4-flute square end mill designed for general-purpose milling in ferrous and non-ferrous metals. Manufactured from high speed steel (HSS) with a right-hand cut and right-hand spiral flute, it delivers consistent chip evacuation and stable cutting geometry. The tool features a 7/8 inch cutting diameter, a 1-7/8 inch length of cut, and a 4-1/8 inch overall length. A 30-degree helix angle balances cutting efficiency with tool rigidity. This end mill belongs to the Cleveland HG-4C series and is installed by machinists and tool-and-die professionals on manual mills and CNC machining centers.

This end mill is suited for milling operations on cast iron, non-ferrous metals, and steel in both production and job-shop environments. Its centercutting geometry allows for direct plunge entry without a pre-drilled hole, adding flexibility in pocket and slot milling applications. The straight cylindrical shank with Weldon flat accommodates standard end mill holders and set-screw style toolholders. The uncoated HSS construction makes it well-suited for lower-speed applications where regrinding is preferred over disposable carbide tooling.

Key Features

• 4-flute spiral design for balanced cutting action and chip clearance
• Centercutting geometry permits direct plunge milling without pilot hole
• 30-degree helix angle optimized for steel, cast iron, and non-ferrous metals
• Straight cylindrical shank with Weldon flat for secure toolholder retention
• Uncoated high speed steel construction supports regrinding and reconditioning
• Regular length profile provides rigidity for standard-depth slotting and profiling

Compatibility

Designed for use on cast iron, non-ferrous metals, and steel workpieces. Part of the Cleveland HG-4C series of regular-length square end mills. Accepts standard end mill holders and Weldon flat set-screw toolholders sized for 7/8 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the spindle before changing tooling. Seat the Weldon flat shank fully into the toolholder and torque the set screw to the toolholder manufacturer specification before engaging the spindle. Verify spindle speed and feed rate against published HSS cutting data for the workpiece material before beginning the cut.
