Sgs 00604 Square End Mill 0.09 in 4 Flute Solid Carbide

Product Description

The SGS 00604 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 0.09 inch cutting diameter and a 0.45 inch length of cut, this tool is built for small-bore slotting, profiling, and finishing passes where tight tolerances are required. The four-flute configuration and 30-degree helix angle promote efficient chip evacuation and smooth surface finishes. Manufactured from micrograin solid carbide, the 00604 offers rigidity and wear resistance suited to demanding cut conditions. The bright, uncoated finish makes it appropriate for use in a range of materials where coating is not specified.

This end mill fits standard CNC machining centers, manual mills, and toolroom applications where small-diameter cutters are required. The straight cylindrical shank measures 0.125 inches in diameter, compatible with standard ER collet systems and similar small-bore toolholding. With an overall length of 2.5 inches, it provides extended reach for work in deeper pockets or fixtures with limited clearance. Single-end construction means the cutter is replaced when worn rather than reversed. Machinists and tool-and-die professionals are the primary installers of this product.

Key Features

• 0.09 inch cutting diameter with a mill diameter tolerance of +0.000 to -0.001 inches for consistent fit
• Four flutes with a 30-degree right-hand spiral helix for smooth chip flow and reduced chatter
• Micrograin solid carbide construction for hardness and edge retention in precision cuts
• Centercutting design allows plunge entry into workpiece material
• Bright, uncoated finish suits a broad range of workpiece materials and cutting fluids
• Straight cylindrical shank with h6 tolerance for accurate seating in collet holders

Compatibility

Designed as an OEM-style replacement for solid carbide square end mills used in standard CNC and manual milling machine setups accepting a 0.125 inch straight cylindrical shank.

Installation Notes

Installation is performed by qualified machinists following standard toolroom procedures. Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Seat the shank fully into the collet or toolholder and torque the clamping mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning production cuts, particularly given the small diameter and tight tolerance of this end mill.
