Cleveland C43299 Square End Mill 3/8 in 4 Flute Powdered Metal

Product Description

The CLEVELAND C43299 is a square end mill designed for precision milling operations in metal fabrication and machining environments. Built from powdered metal, this single-end tool delivers consistent cutting performance in ferrous and non-ferrous materials. The 4-flute configuration and 30-degree helix angle support efficient chip evacuation and smooth surface finishes. With a 3/8 inch cutting diameter, 3/4 inch length of cut, and 2-1/2 inch overall length, it fits standard toolholding setups used in CNC and manual milling applications. The uncoated finish makes it well suited for use with cutting fluid in general-purpose shop environments. Installed by machinists and tool-and-die professionals.

This end mill is used in general-purpose milling applications including slotting, profiling, and peripheral milling on mills, machining centers, and similar equipment. The coarse pitch and right-hand cut with right-hand flute direction are standard configurations for typical ferrous and non-ferrous stock removal. The 3/8 inch shank diameter fits common collets and end mill holders. It is part of the CLEVELAND PMRC series, which is oriented toward powdered metal right-hand cut tooling for production and job-shop use.

Compatibility

Designed as an OEM-style replacement or standard tooling option for milling machines and machining centers accepting a 3/8 inch shank end mill in standard collets or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or holder and torque the retention system per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut.
