Sgs 35107 Square End Mill 3/8 in 6 Flute Solid Carbide

Product Description

The SGS 35107 is a solid carbide square end mill designed for precision metal removal in demanding machining applications. Built on the Series 51L platform, it features a 0.375-inch cutting diameter, six flutes, and a 41-degree variable-index helix geometry that promotes aggressive chip evacuation and reduced chatter. The titanium nitride (TiN) coating adds surface hardness and lubricity to extend tool life across high-cycle production runs. At 4 inches overall length with a 2.125-inch reach, this long-reach configuration handles deep-pocket and extended-reach milling where standard-length tools fall short. It is installed and operated by machinists and CNC tooling professionals in job shop and production environments.

This end mill is suited for milling operations on a range of workpiece materials including steels, stainless steels, cast irons, non-ferrous metals, and high-temperature alloys, corresponding to material codes H, K, M, P, and S. The right-hand cut, right-hand spiral flute geometry with a straight-cylindrical shank makes it a direct fit for standard ER collet chucks and end mill holders. Its centercutting capability allows plunge entry as well as conventional and climb milling passes. The long-reach body paired with the 0.5-inch length of cut is well matched to deep-slot and contour work where tool clearance is critical.

Key Features

• 0.375-inch cutting diameter with 0.5-inch length of cut and 2.125-inch reach length
• Six-flute, 41-degree helix spiral geometry with variable index for vibration reduction
• Micrograin solid carbide substrate for rigidity and wear resistance
• Titanium nitride (TiN) coating for improved surface hardness and tool longevity
• Centercutting design permits plunge milling as well as peripheral cuts
• Series 51L long-length classification for extended-reach applications

Compatibility

Compatible with workpiece material codes H, K, M, P, and S covering steels, stainless steels, cast irons, non-ferrous metals, and high-temperature alloys. Fits standard straight-cylindrical shank tool holders with a 0.375-inch bore. No specific machine model compatibility was stated by the manufacturer for this part number.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Before changing tooling, de-energize the machine spindle and confirm the tool holder is fully released before handling. Verify collet bore size matches the 0.375-inch shank diameter and torque the retention nut to the tool holder manufacturer specification. Inspect the TiN coating and cutting edges for chips before each use; a damaged edge can cause workpiece deflection and surface finish defects.
