Cleveland C31948 Square End Mill 3/4 in 4 Flute Ticn PM-4

Product Description

The CLEVELAND C31948 is a 4-flute square end mill designed for demanding metal removal in machining centers and manual mills. Built from M42 powdered metal with a TiCN finish, this stub-length tool runs a 0.75 inch cutting diameter with a 0.75 inch length of cut and a 0.75 inch straight-cylindrical shank that also accepts a Weldon flat drive. The right-hand spiral flute geometry and 37-degree helix angle promote efficient chip evacuation and stable cutting at elevated speeds and feeds. Centercutting capability allows plunge entry. This end mill is suited for machinists working hardened steels, cast irons, stainless alloys, and exotic materials.

The C31948 is used in production and job-shop environments where consistent tool life and finish quality matter in tough workpiece materials. The PM-4 series designation places this tool in a powdered metal line optimized for the primary workpiece material codes H, K, M, P, and S, which correspond to hardened steels, cast irons, stainless steels, carbon and alloy steels, and high-temperature alloys. The 3 inch overall length and stub classification keep the tool stiff and reduce deflection in short-reach applications.

Key Features

• M42 powdered metal construction for elevated red-hardness and wear resistance
• TiCN coating extends tool life against abrasive and stainless workpiece materials
• 37-degree right-hand spiral flute promotes efficient chip evacuation
• Centercutting geometry allows direct plunge and ramping entry
• Straight-cylindrical shank with Weldon flat accommodates set-screw and collet toolholders
• Stub overall length reduces deflection in short-reach setups

Compatibility

Designed for use in machining applications involving workpiece material codes H, K, M, P, and S as specified in the PM-4 series. Accepts standard 3/4 inch collets, end mill holders, and Weldon-style set-screw toolholders.

Installation Notes

Installation is performed by qualified machinists following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the holder and torque set screws to the toolholder specification. Verify runout with a dial indicator before commencing a cut to maximize tool life and surface finish.
