Sgs 43301 Square End Mill 0.1181 in 2 Flute Solid Carbide

Product Description

The SGS 43301 is a solid carbide square end mill engineered for precision milling operations requiring extended reach. With a 0.1181-inch (3 mm) mill diameter and a 0.9843-inch (25 mm) length of cut, this tool handles deep-cavity and slot-milling work where standard-length end mills fall short. The micrograin carbide construction provides hardness and edge retention across a broad range of workpiece materials. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. The bright, uncoated finish makes it suitable for a wide variety of materials without concern for coating compatibility. Machinists and tooling professionals install this tool in CNC machining centers and manual mills.

The SGS 43301 belongs to the Series 3XLM extra-long end mill family. It is suited for milling operations in materials coded H, K, M, N, P, and S under standard workpiece material classifications, covering hardened steels, cast irons, stainless steels, non-ferrous metals, general steels, and superalloys. The extra-long length type makes it appropriate for deep-pocket milling, extended-reach profiling, and applications where spindle clearance from the workpiece is required. Single-end configuration means the cutting end is one-directional, which is standard for this tool class.

Key Features

• Micrograin solid carbide construction for high hardness and edge retention
• 0.9843-inch length of cut supports deep-cavity and extended-reach milling
• 30-degree spiral helix angle promotes chip evacuation and reduces cutting forces
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• Bright, uncoated finish compatible with a wide range of workpiece material types
• Center-cutting capable, allowing direct plunge entry into workpieces

Compatibility

Designed for use across workpiece material categories H, K, M, N, P, and S as designated by the SGS Series 3XLM classification. Fits standard straight-cylindrical tool holders and collets accepting a 0.1181-inch (3 mm) shank diameter.

Installation Notes

Installation is performed by a machinist or tooling technician using a collet or end mill holder rated for the 3 mm straight-cylindrical shank. Ensure the machine spindle is fully stopped and the tool is seated to the recommended gauge-line depth before tightening. Verify runout with a dial indicator after installation, as runout is critical at this small diameter. Follow shop safety protocols and machine manufacturer guidelines for tool engagement and feed rates.
