Accupro 12182779 Square End Mill 0.1969 in 4 Flute Carbide

Product Description

The ACCUPRO 12182779 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. It carries a 0.1969 inch (5.00 mm) mill diameter with a 0.3937 inch (10.00 mm) length of cut, making it a stub-length tool suited for rigidity in tight setups. The TiCN (titanium carbonitride) coating improves wear resistance and reduces friction at the cutting edge. With 4 spiral flutes, a 40-degree helix angle, and a micrograin carbide substrate, this end mill is built for smooth chip evacuation and consistent edge life in production milling environments. Installed by machinists and CNC operators in job shops and manufacturing facilities.

This end mill is used in vertical machining centers, CNC mills, and manual mills where a small-diameter, stub-length tool is required. The centercutting geometry allows plunge entry, expanding its use in slot milling, profiling, and ramping operations. Right-hand cut and right-hand flute orientation match standard spindle rotation. The 6.00 mm shank diameter fits standard collet chucks and shrink-fit holders common in precision machining setups. It is appropriate for applications requiring close tolerances and fine surface finishes in small-feature workpieces.

Key Features

• Solid micrograin carbide construction for extended tool life and edge stability
• TiCN coating reduces wear and improves performance in ferrous materials
• 4 spiral flutes with 40-degree helix angle for efficient chip evacuation
• Centercutting design allows plunge milling and slot entry
• Stub length (Length Type: Stub) provides added rigidity in short-reach applications
• Right-hand cut, right-hand flute for standard spindle compatibility

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard collet, shrink-fit, or milling chuck toolholders accepting a 6.00 mm shank diameter.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and locked out before changing tooling. Verify holder bore size matches the 6.00 mm shank diameter and torque the collet nut or set screw to toolholder manufacturer specifications. Confirm runout with a dial indicator after seating to protect both the tool and workpiece from premature wear or dimensional error.
