Accupro 12184530 Ball End Mill 3/8 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12184530 is a single-end ball end mill engineered for precision milling in demanding metalworking and machining applications. Built from micrograin solid carbide and coated with TiCN (Titanium Carbonitride), this tool delivers extended tool life and improved wear resistance compared to uncoated carbide. The 3/8 inch cutting diameter and 1-1/2 inch length of cut make it well-suited for profiling, contouring, and slotting operations. A 40-degree right-hand helix promotes efficient chip evacuation and reduces cutting forces. The 6 inch overall length qualifies this as an extra-long reach tool, providing access to deep cavities and recessed features without fixture interference.

This end mill is designed for use in CNC machining centers, vertical mills, and manual milling machines where ball-nose geometry is required for 3D contour work, die and mold machining, and finish passes on complex surfaces. The 3/8 inch shank diameter suits standard ER collet chucks and end mill holders common in production and job-shop environments. Right-hand cutting direction and spiral flute geometry make this tool compatible with conventional and climb milling strategies on ferrous and non-ferrous materials.

Key Features

• Micrograin solid carbide substrate for rigidity and edge retention in hard materials
• TiCN coating increases surface hardness and reduces friction at the cutting edge
• 40-degree right-hand helix angle supports efficient chip evacuation
• Extra-long 6 inch overall length provides reach into deep cavities and tall workpieces
• 3 flute design balances chip load capacity with core strength at 3/8 inch diameter
• Single-end configuration; ball nose geometry suited for 3D contouring and profiling

Compatibility

Designed as an OEM-style solid carbide ball end mill compatible with standard 3/8 inch end mill holders and ER collet systems used in CNC and manual milling applications.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before loading or removing the tool. Secure the shank to the full recommended engagement depth in the holder to prevent pullout under cutting load. Verify runout with a dial indicator after tool installation, as excess runout accelerates wear on carbide end mills and degrades surface finish.
