Sgs 34640 Square End Mill 2 Flute Solid Carbide Series 47E

Product Description

The SGS 34640 is a solid carbide square end mill designed for precision material removal in metalworking and machining applications. It features a 0.25-inch cutting diameter, a 0.375-inch length of cut, and a 4-inch overall length on a straight cylindrical 0.25-inch shank. The two-flute geometry and 35-degree helix angle promote efficient chip evacuation and smooth cutting action in non-ferrous metals. This is a right-hand cut, right-hand flute tool with a centercutting design, allowing plunge entry. It runs uncoated and belongs to the SGS Series 47E line, intended for use in CNC mills and manual milling machines by machinists and toolroom professionals.

This end mill is suited for milling non-ferrous metals such as aluminum, brass, copper, and similar materials in production and job-shop environments. The extended reach geometry, with a 2.125-inch reach length, allows access to deeper features or stepped pockets without changing setups. The spiral flute and regular-length classification make it a standard workhorse tool for slotting, profiling, and pocketing operations where clean surface finish and accurate dimensions are required.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous machining
• Centercutting design allows direct plunge cuts without pre-drilling
• 35-degree helix angle promotes chip flow and reduces cutting forces
• Extended reach of 2.125 inches accommodates deeper features and pockets
• Right-hand cut and right-hand flute for standard spindle operation
• Uncoated finish suited to non-ferrous materials where coating buildup is a concern

Compatibility

Designed as a standard straight-shank end mill compatible with 0.25-inch collets, end mill holders, and shrink-fit toolholders used in CNC machining centers and manual knee mills. Primary workpiece material classification is non-ferrous metal (Material Code N).

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerance. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool. Verify collet or holder bore diameter matches the 0.25-inch shank before tightening. Observe the shank diameter tolerance of +0.00000/-0.00035 inches when selecting a precision toolholder to minimize runout.
