Guhring 9031130158700 Square End Mill 5/8 Inch 4 Flute

Product Description

The GUHRING 9031130158700 is a solid carbide square end mill designed for high-performance milling in demanding shop environments. Built on the Series 3113 platform, it features a variable helix geometry with flute angles of 35 and 38 degrees that reduces harmonics and chatter during cutting. The FIREX coating provides thermal and wear resistance for extended tool life when cutting ferrous materials. At 5/8 inch in diameter with a 3/4 inch length of cut and 3 inch overall length, this is a stub-length tool suited for rigidity-critical applications. It is installed by machinists and CNC operators in production and job-shop settings.

This end mill is intended for use on CNC machining centers and manual mills where precise, clean square-shoulder cuts are required. Its centercutting capability allows plunge entry without a pre-drilled hole. Primary workpiece materials include cast iron and steel. Secondary applications cover hard materials, stainless steel, and other difficult-to-machine alloys. The straight cylindrical shank with h6 tolerance fits standard collet chucks and end mill holders designed for 5/8 inch tooling.

Key Features

• Variable helix design at 35 and 38 degrees reduces vibration and improves surface finish
• FIREX coating provides high hardness and heat resistance for extended tool life in steel and cast iron
• Centercutting geometry allows direct plunge milling without a pilot hole
• 4-flute spiral configuration balances chip evacuation with cutting edge strength
• Stub-length body maximizes rigidity and minimizes deflection in tight setups
• Right-hand cut and right-hand flute orientation compatible with standard spindle rotation

Compatibility

Designed for use with standard 5/8 inch collet chucks and end mill holders accepting a straight cylindrical shank with h6 tolerance. Primary workpiece materials are cast iron and steel; secondary materials include hard materials and stainless steel.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before loading or removing the tool from its holder. Seat the shank fully into the collet or holder to the recommended gauge depth before tightening. Verify runout with a dial indicator after seating, as excessive runout will accelerate wear on a solid carbide tool and degrade surface finish.
