Sgs 48554 Square End Mill 0.315 in 4 Flute Altin Carbide

Product Description

The SGS 48554 is a solid carbide square end mill designed for precision metal removal in CNC machining and manual milling operations. It features a 0.315 inch mill diameter, a 0.7874 inch length of cut, and a 4-flute spiral geometry with a 30-degree helix angle. The AlTiN coating improves heat resistance and extends tool life in demanding cutting applications. The micrograin carbide substrate provides edge stability at higher feed rates and spindle speeds. This tool is used by machinists and tool-and-die professionals in job shops, production facilities, and maintenance machining environments.

The SGS 48554 is suited for milling operations on a broad range of workpiece materials, including cast iron, non-ferrous metals, stainless steel, high-temperature alloys, and steel. Primary workpiece material codes H, K, M, N, P, and S are supported. The straight-cylindrical shank with a 0.315 inch diameter fits standard ER and side-lock toolholders. This is a single-end, right-hand cut tool with right-hand flute direction. It carries a regular length classification with a length-of-cut range of 0.700 to 0.800 inches, making it appropriate for general-purpose slotting, profiling, and peripheral milling where deep extended reach is not required.

Key Features

• AlTiN coating for improved thermal resistance and longer tool life in hard and abrasive materials
• Micrograin solid carbide substrate for edge rigidity and dimensional accuracy
• 30-degree helix angle with spiral flute geometry for smooth chip evacuation
• 4-flute configuration balances material removal rate with chip clearance
• Right-hand cut with right-hand flute direction for standard CNC and manual mill setups
• Center-cutting design allows plunge entry without a pre-drilled hole

Compatibility

Designed as a direct-fit replacement for Series 1M solid carbide square end mills requiring a 0.315 inch straight-cylindrical shank. Compatible with standard ER collet chucks, shrink-fit holders, and side-lock holders accepting an 8 mm or 0.315 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping torque and runout specifications. Ensure the spindle and toolholder bore are clean and free of chips before seating the shank. Confirm shank engagement depth meets the toolholder minimum before securing. Verify spindle direction is set to right-hand rotation before initiating any cut.
