Guhring 9037360040000 Square End Mill 0.157 in 4 Flute Carbide

Product Description

The GUHRING 9037360040000 is a solid carbide square end mill engineered for high-performance milling in demanding metalworking applications. Part of the Series 3736 lineup, this single-end tool features a 0.157-inch (4.00 mm) cutting diameter, a 0.433-inch length of cut, and four spiral flutes with a variable helix design. The FIREX coating provides enhanced heat resistance and wear protection, extending tool life in abrasive cutting conditions. The variable helix angle of 35 and 38 degrees reduces harmonic chatter, improving surface finish and dimensional accuracy. Centercutting capability allows for direct plunge entry into workpiece material without a pilot hole.

This end mill is suited for milling operations on cast iron, steel, stainless steel, and hard materials in both production and job-shop environments. The 6.00 mm straight cylindrical shank fits standard collet and toolholder systems, while the reduced neck diameter of 3.80 mm provides clearance in pocketing and slotting operations. It is commonly used in CNC machining centers by machinists and toolroom technicians working with ferrous and hard-material workpieces requiring tight tolerances and reliable tool life.

Key Features

• FIREX coating for improved wear resistance and heat management in ferrous and hard-material cutting
• Variable helix at 35 and 38 degrees reduces vibration and chatter for better surface finish
• Centercutting design allows direct plunge milling without a pre-drilled pilot hole
• Four spiral flutes with right-hand cut and right-hand flute orientation for standard CNC setups
• Solid carbide construction provides rigidity and dimensional stability at elevated cutting speeds
• Reduced neck diameter (3.80 mm) provides clearance in deep-pocket and slot milling

Compatibility

Designed for use with standard straight-bore collets and toolholders accepting a 0.2362-inch (6.00 mm) shank diameter. Primary workpiece materials include cast iron and steel; secondary applications include hard materials and stainless steel per Series 3736 design intent.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the collet or toolholder to the recommended engagement depth and torque the retention system per the toolholder manufacturer specifications. Confirm runout with a dial indicator before beginning a production cut, particularly in tight-tolerance applications.
