Accupro 12185378 Ball End Mill 0.375in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12185378 is a double-end ball end mill designed for precision milling operations in metal and alloy workpieces. Built from solid carbide and coated with AlTiN (aluminum titanium nitride), it handles high-heat cutting environments where tool life and dimensional accuracy matter. The 0.375-inch diameter with a 0.5-inch length of cut and 40-degree helix angle support aggressive material removal while maintaining surface finish quality. This tool is used by machinists and tool-and-die professionals running CNC vertical or horizontal milling centers.

This end mill is suited for contour milling, profiling, and 3D surfacing operations in ferrous metals, stainless steels, and hardened alloys. The double-end configuration extends usable tool life by providing two cutting ends per shank. The right-hand cut and right-hand flute spiral direction make it compatible with standard spindle configurations. Stub length geometry keeps the tool rigid in tight-clearance setups where deflection must be minimized.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating provides oxidation resistance and extended tool life at elevated cutting temperatures
• Double-end design offers two usable cutting ends per tool
• 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces
• 4-flute spiral configuration balances material removal rate with surface finish quality
• Right-hand cut and right-hand flute direction compatible with standard CNC spindle setups

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC milling machines accepting a 0.375-inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. De-energize and lock out the machine spindle before changing tooling. Seat the shank fully and evenly in a matched collet or end mill holder and torque the retention system per the machine manufacturer's specifications. Confirm runout with a dial indicator before beginning a production cut.
