Sgs 34749 Square End Mill 3/4 in 3 Flute Solid Carbide

Product Description

The SGS 34749 is a solid carbide square end mill designed for high-precision milling of non-ferrous metals. It features a 3/4-inch cutting diameter, a 2.25-inch length of cut, and a 5-inch overall length with a straight cylindrical 3/4-inch shank. Three spiral flutes with a 38-degree helix angle and a TiB2 (titanium diboride) finish deliver efficient chip evacuation and extended tool life on aluminum, copper, brass, and similar materials. This is a single-end, right-hand cut, right-hand flute configuration in SGS Series 43.

This end mill is suited for slotting, profiling, and peripheral milling operations on non-ferrous workpieces in CNC machining centers and manual milling machines. The regular-length geometry and straight shank make it a standard fit for collet chucks and end mill holders across common spindle sizes. It is typically selected for production shops, job shops, and toolrooms running non-ferrous materials where surface finish and tool life are priorities.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous applications
• TiB2 coating reduces built-up edge and improves lubricity on aluminum and copper alloys
• 38-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Three flutes provide a balance of chip clearance and cutting edge strength
• Right-hand cut, right-hand spiral flute — standard CNC spindle rotation compatible
• Not center-cutting — not intended for direct plunge entry; use ramping or helical entry

Compatibility

Designed as an OEM-style tooling option for CNC machining centers and knee mills equipped with standard 3/4-inch collet chucks or end mill holders; primary workpiece material designation is non-ferrous metal (material code N).

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle before mounting or removing the tool. Secure the straight shank in a properly sized collet or end mill holder torqued to the machine manufacturer's specification. Because this end mill is not center-cutting, avoid direct axial plunge — use ramping, helical interpolation, or pre-drilled entry points.
