Sgs 02397 Square End Mill 0.1 in 2 Flute Altin Carbide

Product Description

The SGS 02397 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. With a 0.1-inch cutting diameter and a 0.15-inch length of cut, this tool is built for tight-tolerance work in small-feature applications. The AlTiN coating provides heat resistance and extended tool life under high-speed cutting conditions. The micrograin carbide substrate delivers hardness and edge retention that standard high-speed steel cannot match. This end mill is installed and operated by machinists and CNC tooling professionals working in job shop, production, and tool-and-die environments.

This end mill suits applications requiring small-diameter, high-precision cuts in ferrous and non-ferrous materials. The 2-flute configuration and 30-degree right-hand helix promote efficient chip evacuation in slotting and peripheral milling operations. The straight cylindrical shank measures 0.125 inches in diameter, making it compatible with standard collet chucks and ER-style toolholders used on CNC mills and manual knee mills. The regular-length profile keeps deflection minimal during light profiling and pocketing passes.

Key Features

• AlTiN coating for high heat resistance and extended tool life in ferrous materials
• Micrograin solid carbide substrate for superior hardness and edge retention
• 2-flute, right-hand spiral geometry with 30-degree helix for efficient chip evacuation
• Centercutting design allows plunge entry into workpiece
• Straight cylindrical shank with h6 tolerance for secure collet holding
• Mill diameter tolerance of +0.000 to -0.001 inches for tight-tolerance fitment

Compatibility

Designed for use in standard ER collet chucks, end mill holders, and straight-bore toolholders with a 0.125-inch bore, as commonly found on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention nut to the toolholder specification. Verify runout with a dial indicator before beginning a cutting pass, as runout in small-diameter end mills accelerates edge wear and can cause premature tool failure.
