Accupro 12184943 Ball End Mill 0.5 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12184943 is a solid carbide ball end mill designed for precision milling operations in metal cutting and machining applications. With a 0.5-inch mill diameter and four flutes, this single-end tool delivers efficient chip evacuation and a smooth finish in ferrous and non-ferrous materials. The 40-degree helix angle promotes aggressive cutting action while reducing chatter. Built from micrograin solid carbide, it holds tight tolerances across extended production runs. The uncoated finish makes it suitable for applications where coating compatibility or re-sharpening is a consideration. Machinists and CNC operators working in job shops, tool rooms, and production environments are the primary users.

This ball end mill is suited for profiling, contouring, slotting, and 3D surface milling on machining centers and CNC mills. The long-length configuration, with a 1-inch length of cut and 4-inch overall length, provides reach for deeper cavity work and stepped-shoulder applications. The right-hand cutting and right-hand flute direction make it compatible with standard spindle rotation on conventional vertical and horizontal machining centers. The 0.5-inch shank diameter fits standard ER and side-lock toolholders commonly found in production shops.

Key Features

• Micrograin solid carbide construction for wear resistance and edge retention
• 4-flute design improves surface finish and feed rate capability
• 40-degree helix angle reduces cutting forces and chatter
• Long-length configuration with 1-inch LOC and 4-inch OAL for deep-reach applications
• Right-hand cut and right-hand spiral for standard CNC spindle compatibility
• Uncoated finish suitable for re-sharpening and select material applications

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in standard 0.5-inch toolholders on CNC machining centers and manual mills with right-hand spindle rotation.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully powered down and locked before changing tooling. Seat the shank fully into the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning production cuts, as excessive runout will accelerate edge wear on carbide tooling.
