Kennametal 2658352 Square End Mill 0.25in 3 Flute Carbide

Product Description

The KENNAMETAL 2658352 is a solid carbide square end mill designed for precise milling operations in metalworking and machining applications. With a 0.25 inch cutting diameter, a 0.75 inch length of cut, and a 0.25 inch shank diameter, this single-end tool delivers a 2.5 inch overall length suited to a wide range of light to moderate stock removal tasks. The three-flute, extra-coarse pitch geometry with a high helix style promotes efficient chip evacuation and smooth cutting action. Built from micrograin solid carbide in an uncoated bright finish, this end mill is installed and run by machinists and CNC tooling technicians working on mills, machining centers, and manual knee mills.

This end mill is suited to slotting, profiling, and peripheral milling in ferrous and non-ferrous materials where a high-helix, center-cutting tool is required. The centercutting capability allows direct plunge entry without a pre-drilled hole. Right-hand cut and right-hand flute orientation match standard spindle rotation on most vertical machining centers. The SFRHEC series designation indicates an extra-coarse pitch configuration optimized for aggressive material removal while maintaining dimensional accuracy at the 0.25 inch diameter range.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance at small diameters
• Three-flute extra-coarse pitch design promotes chip clearance in slotting and profiling cuts
• High helix style supports smooth cutting action and reduced heat buildup
• Centercutting geometry allows direct plunge entry without pre-drilling
• Uncoated bright finish suitable for use with cutting fluids across a range of workpiece materials
• Right-hand cut and right-hand flute for standard spindle compatibility

Compatibility

Designed as an OEM-style replacement and standard tooling option for 0.25 inch shank collet holders, end mill holders, and hydraulic chucks used on vertical machining centers and manual mills within the SFRHEC series application range.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 0.25 inch shank fully into the collet or holder and torque to the holder specification per the toolholder manufacturer guidelines. Confirm runout with a dial indicator before beginning cuts, and verify chip evacuation is adequate for the selected feed and speed parameters.
