Accupro 12184305 Ball End Mill 0.25in 2 Flute Solid Carbide Ticn

Product Description

The ACCUPRO 12184305 is a single-end ball end mill designed for profiling, contouring, and 3D machining operations in metal and composite materials. Built from micrograin solid carbide and coated with TiCN (Titanium Carbonitride), it delivers strong wear resistance and thermal stability across demanding cutting applications. The 0.25 inch diameter cutting end pairs with a 40-degree helix angle and two right-hand spiral flutes, producing efficient chip evacuation and a smooth surface finish. At 6 inches overall length with a 1.5 inch length of cut, this is an extra-long reach tool suited for deep cavity and mold work where standard-length mills cannot reach.

This end mill is used in CNC machining centers and manual milling operations where precise ball-nose profiles are required. The extra-long 6 inch overall length makes it well suited for deep pocket milling, rib machining, and contoured surface finishing in die and mold work, aerospace components, and general metalworking. The 0.25 inch shank diameter fits standard collet chucks and end mill holders common in both production and job-shop environments. Right-hand cutting direction is compatible with conventional CNC spindle rotation.

Key Features

• Micrograin solid carbide construction for high rigidity and wear resistance in ferrous and non-ferrous materials
• TiCN coating improves surface hardness and reduces built-up edge in steel and stainless applications
• 40-degree helix angle promotes aggressive chip evacuation and reduces cutting forces
• Extra-long 6 inch overall length provides deep-reach capability for cavity and mold machining
• Two right-hand spiral flutes deliver clean ball-nose profile geometry for 3D contouring
• Single-end design with 0.25 inch shank for direct collet or end mill holder mounting

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 0.25 inch shank diameter via ER collet chucks, side-lock holders, or shrink-fit tooling systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Seat the shank to the recommended minimum insertion depth for the holder type in use to prevent deflection, especially critical at this extra-long reach. Verify runout with a dial indicator after clamping before initiating any cutting cycle.
