Sgs 31734 Square End Mill 0.625 in 4 Flute Solid Carbide

Product Description

The SGS 31734 is a solid carbide square end mill designed for precision milling operations in metal, composite, and hard material applications. It features a 0.625-inch cutting diameter, a 2.25-inch length of cut, and a 5-inch overall length, making it well-suited for deep-reach slotting, profiling, and peripheral milling. The micrograin carbide substrate paired with a Titanium Nitride (TiN) coating provides wear resistance and extended tool life in demanding cutting conditions. Four spiral flutes with a 30-degree helix angle and a variable index design promote smooth chip evacuation and reduce chatter. This end mill is centercutting, supporting plunge operations as needed.

The SGS 31734 is intended for use in CNC machining centers and manual milling machines where long-reach capability is required. Its long-length classification and 2.25-inch length of cut accommodate deeper pockets and taller workpiece features that standard-length end mills cannot reach. The straight cylindrical shank fits standard ER and side-lock toolholders. It is appropriate for machinists, tool-and-die makers, and production shops working in ferrous and non-ferrous materials.

Key Features

• 0.625-inch cutting diameter with a mill diameter tolerance of +0.000 / -0.002 inches for consistent dimensional accuracy
• Micrograin solid carbide construction for rigidity and resistance to edge wear
• Titanium Nitride (TiN) coating reduces friction and extends tool life in steel and cast iron
• 30-degree helix angle with spiral flutes for efficient chip evacuation
• Variable index flute spacing reduces harmonic vibration and chatter during cutting
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand cut, right-hand flute configuration — compatible with standard spindle rotation

Compatibility

Designed for use in standard CNC and manual milling machines accepting a 0.625-inch straight cylindrical shank. Part of the SGS Series 1L long-length end mill lineup.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the shank. Verify runout with a dial indicator after clamping to maintain dimensional accuracy. Follow the machine tool manufacturer guidelines for toolholder torque and stick-out length.
