Sgs 00878 Square End Mill 7/64 in 2 Flute Solid Carbide

Product Description

The SGS 00878 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. Built on the Series 1610 platform with a micrograin carbide substrate, it delivers the rigidity and edge retention required for tight-tolerance work in CNC machining centers and manual mills. The cutter measures 0.1094 inches (7/64 inch) in diameter with a 0.3281-inch (21/64 inch) length of cut and a 0.1250-inch (1/8 inch) straight-cylindrical shank. Two spiral flutes provide efficient chip evacuation in the small-diameter range. The uncoated finish makes it suitable for use with a wide range of cutting fluids and applications where coating buildup would affect dimensional accuracy.

This end mill is used in job shop, production, and toolroom environments where small-diameter milling is required. Typical applications include slotting, profiling, and plunge cutting in aluminum, brass, steel, and similar machinable materials. The centercutting geometry allows direct plunge entry without a pre-drilled pilot hole. Right-hand cut and right-hand flute configuration matches standard CNC spindle rotation. The regular-length body keeps the tool compact and maximizes rigidity at this diameter.

Key Features

• Micrograin solid carbide construction for superior wear resistance and edge integrity
• Centercutting design allows direct plunge milling without pilot drilling
• Two spiral flutes promote chip clearance in small-diameter cuts
• Right-hand cut, right-hand flute configuration for standard CNC and manual mill spindles
• Straight-cylindrical shank fits standard 1/8-inch collets and end mill holders
• Mill diameter tolerance of +0.0000 / -0.0008 inches ensures consistent dimensional results

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC machining centers and manual mills equipped with 1/8-inch collet or end mill holder systems.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the collet or holder to the recommended engagement depth to prevent pullout under load. Inspect the cutting edges for chips or wear before each use, particularly at this small diameter where deflection and breakage risk is elevated.
