Accupro 12181648 Square End Mill 0.315 in 2 Flute Carbide

Product Description

The ACCUPRO 12181648 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. It features a 0.315 inch (8.00 mm) diameter, a 0.4724 inch (12.00 mm) length of cut, and a 2-flute spiral configuration with a 40-degree helix angle. The cutting edges are finished with TiCN (Titanium Carbonitride) coating, which increases surface hardness and reduces friction for improved tool life in harder materials. The micrograin carbide substrate provides consistent edge integrity across interrupted cuts and finishing passes. This is a stub-length end mill, making it well suited for rigid setups where minimal overhang is required.

This end mill is intended for use by machinists and tool-and-die professionals working on CNC machining centers, vertical mills, and manual knee mills. The stub-length profile reduces deflection in tight-tolerance work. The centercutting design allows plunge entry, adding versatility for pocketing and slotting operations. Right-hand cut and right-hand flute orientation make this a standard configuration compatible with conventional spindle rotation on most milling equipment.

Key Features

• Solid micrograin carbide construction for sharp, durable cutting edges
• TiCN finish for increased wear resistance and reduced heat buildup
• 2-flute spiral design with 40-degree helix angle for efficient chip evacuation
• Centercutting capability allows plunge milling into solid material
• Stub-length body minimizes tool deflection in close-tolerance applications
• Right-hand cut and right-hand flute for standard CNC spindle compatibility

Compatibility

Designed as a standard shank square end mill with an 8.00 mm (0.315 inch) shank diameter for use in collet chucks, end mill holders, and shrink-fit tooling systems that accept this shank size.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power isolated per shop lockout-tagout procedures. Confirm collet or holder bore matches the 8.00 mm shank diameter before seating the tool. Inspect the collet and holder for runout before beginning a cut. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.
