Accupro 12184287 Ball End Mill 0.375 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12184287 is a single-end ball end mill designed for contour milling, profiling, and 3D finishing operations in metalworking and machining applications. It features a 0.375 inch cutting diameter, a 1 inch length of cut (LOC), and a 4 inch overall length (OAL). Constructed from micrograin solid carbide and coated with titanium carbonitride (TiCN), this tool delivers strong wear resistance and extended tool life in ferrous and non-ferrous materials. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action in medium-to-hard workpiece materials.

This end mill is suited for CNC machining centers and manual mills where precise ball-nose profiling is required. The 3/8 inch shank diameter fits standard ER collets and end mill holders commonly found in production and job shop environments. The long-reach geometry makes it appropriate for cavity work and contoured surface finishing where a standard-length tool would not reach. It is typically installed and operated by machinists and CNC programmers working in general metalworking, die and mold, and precision parts manufacturing.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in demanding cuts
• TiCN coating reduces friction and increases surface hardness for longer tool life
• 40-degree helix angle promotes efficient chip evacuation and reduces cutting heat
• 2-flute geometry provides clearance for chip flow in slotting and profiling operations
• Single-end ball nose profile suited for 3D contouring and radius floor work
• Right-hand cut and right-hand flute direction for standard spindle rotation

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and knee mills using 3/8 inch collet or end mill holder tooling systems.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling setup procedures. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify runout after installation using a dial indicator to confirm proper seating in the collet or holder. Follow machine manufacturer guidelines and applicable shop safety protocols when setting feeds, speeds, and depth of cut for the workpiece material.
