Gws 315203 Square End Mill 1 Inch 3 Flute Solid Carbide

Product Description

The GWS 315203 is a single-end square end mill ground from submicron solid carbide and finished with a ZrN (zirconium nitride) coating. It carries a 1.0000 inch cutting diameter, a 1.25 inch length of cut, and a 37-degree helix angle with right-hand cut and right-hand upcut flute geometry. The three-flute configuration and centercutting capability make it suitable for slotting, profiling, and plunge operations in a broad range of workpiece materials. Machinists and tool-and-die professionals select this series when consistent edge life and dimensional accuracy are required in production environments.

The 315203 belongs to GWS Series 2031 and is intended for use on vertical and horizontal CNC machining centers as well as manual knee mills equipped with an appropriate collet or end mill holder accepting a 1 inch shank. The ZrN coating improves heat resistance and lubricity, making the cutter well suited for ferrous and non-ferrous materials where surface finish and tool life are priorities. Overall length is 5 inches, giving adequate clearance for typical fixture setups without requiring extended-reach tooling.

Key Features

• Submicron solid carbide substrate for improved rigidity and edge retention
• ZrN coating enhances heat resistance and reduces built-up edge
• 37-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Right-hand upcut flute geometry for standard milling operations
• Centercutting design allows direct plunge entry into workpiece material
• Three-flute layout balances chip clearance and feed rate capability

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for CNC machining centers and manual mills accepting a 1 inch straight shank in a standard collet, end mill holder, or Weldon-style holder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before inserting or removing the cutter. Seat the shank to the full recommended engagement depth in the holder and verify runout with a dial indicator before beginning a cut. Do not exceed the cutter's rated depth of cut or feed rate for the workpiece material being machined.
