Sgs 43315 Square End Mill 0.315in 2 Flute Carbide 3XLM

Product Description

The SGS 43315 is a solid carbide square end mill designed for precision material removal in CNC milling and machining operations. Built on the SGS Series 3XLM platform, this extra-long tool features a 0.315-inch mill diameter, a 0.9843-inch length of cut, and a 30-degree helix angle. The micrograin carbide construction delivers the rigidity and edge retention needed for demanding cuts in a range of workpiece materials. With a bright, uncoated finish and a straight-cylindrical shank, this end mill suits professionals running close-tolerance milling programs in production or job-shop environments.

The SGS 43315 is suited for milling applications involving hard metals, stainless and heat-resistant alloys, cast irons, non-ferrous materials, and high-temperature alloys, as reflected in its primary workpiece material codes H, K, M, N, P, and S. The extra-long length of cut makes it appropriate for deep-pocket milling, slotting, and profiling operations where standard-length tools cannot reach. It is used in both vertical and horizontal machining centers by machinists and CNC operators working in production and toolroom settings.

Key Features

• 0.315-inch (8 mm) mill diameter with a mill diameter tolerance of +0.000 / -0.050 mm for consistent fit
• 0.9843-inch (25 mm) length of cut — extra-long Series 3XLM geometry for deep-reach applications
• 30-degree right-hand spiral flute with right-hand cut for efficient chip evacuation
• 2-flute configuration supports slotting, profiling, and deep-pocket work
• Micrograin solid carbide construction for edge retention in hard and abrasive materials
• Center-cutting capability allows direct plunge entry without pre-drilling
• Bright, uncoated finish — ready to run or re-coat per shop preference

Compatibility

Designed as a direct-fit replacement or upgrade end mill for CNC machining centers and manual mills accepting a 0.315-inch straight-cylindrical shank; compatible with workpiece materials classified under SGS material codes H, K, M, N, P, and S, covering steel, stainless, cast iron, non-ferrous, and high-temperature alloy families.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Secure the shank in an appropriate collet or end mill holder, verifying runout before beginning a cut. Power down the spindle and confirm the machine is in a safe state before changing tooling. Follow applicable shop safety protocols and machine manufacturer guidelines for tool change procedures.
