Sgs 31737 Square End Mill 0.125 in 4 Flute Solid Carbide

Product Description

The SGS 31737 is a solid carbide square end mill designed for precision milling in demanding trade and industrial applications. With a 0.125-inch mill diameter, a 0.750-inch length of cut, and a 2.25-inch overall length, this tool delivers tight-tolerance material removal in a compact profile. The four-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and a stable cut. A TiCN (Titanium Carbonitride) finish increases surface hardness and wear resistance, extending tool life in abrasive materials. The micrograin carbide substrate supports sharper edges and better edge retention than standard carbide grades.

This end mill is suited for machining a broad range of workpiece materials including ferrous metals, cast iron, stainless steel, non-ferrous metals, high-temp alloys, and plastics, consistent with its Primary Workpiece Material Codes H, K, M, N, P, and S. The long-series 1L profile and 0.125-inch straight-cylindrical shank make it a practical choice for slots, pockets, and profiling cuts where reach matters. It is centercutting, allowing direct plunge entry into the workpiece. Variable index geometry helps suppress chatter during high-feed passes.

Key Features

• Solid micrograin carbide construction for improved edge retention and rigidity
• TiCN coating for enhanced wear resistance in abrasive and hard workpiece materials
• Four flutes with 30-degree right-hand spiral helix for efficient chip flow
• Centercutting capability allows plunge milling without a pre-drilled pilot hole
• Variable index flute spacing reduces harmonic chatter in high-feed applications
• Long-series 1L designation provides extended reach for deep-slot and pocket work
• Mill diameter tolerance of plus 0.000 and minus 0.002 inches for consistent fit

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 0.125-inch straight-cylindrical shank collets and tool holders used in CNC machining centers and manual mills accepting 1/8-inch shank tooling.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the tool holder collet is clean and free of debris before seating the shank to the specified depth. Confirm runout with a dial indicator before cutting to protect the tool and workpiece. Follow machine manufacturer torque specifications for drawbar and collet nut tightening.
