Accupro 12184853 Ball End Mill 0.6875 in 4 Flute Carbide

Product Description

The ACCUPRO 12184853 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining environments. With a 0.6875-inch mill diameter and a 1-inch length of cut, this single-end tool is built for contouring, profiling, and finishing passes on curved or complex surfaces. The 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces. Manufactured from micrograin solid carbide, it delivers rigidity and edge retention that high-speed steel tooling cannot match. CNC machinists and tool-and-die professionals are the primary users of this type of end mill.

This ball end mill is suited for use on CNC vertical machining centers and manual mills where 3D contouring and radius milling are required. The stub-length configuration provides added stiffness and reduced deflection in applications where cutting depth does not demand extended reach. The uncoated finish makes it compatible with a broad range of workpiece materials, including ferrous and non-ferrous metals, and allows for easy inspection of tool wear. It is a practical choice for production shops and toolrooms handling die work, mold making, and general machining tasks.

Key Features

• Micrograin solid carbide construction for superior edge retention and rigidity
• 40-degree right-hand helix angle promotes efficient chip evacuation
• Ball end geometry enables contouring, profiling, and radius milling
• 4-flute design balances material removal rate with surface finish quality
• Stub-length body minimizes deflection in tight-reach applications
• Uncoated finish supports use across a wide range of workpiece materials

Compatibility

Designed as a standard single-end ball end mill for use in CNC and manual milling machines accepting a 3/4-inch straight shank collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the spindle is fully powered down and locked out before changing tooling. Use a properly sized collet or end mill holder matching the 3/4-inch shank diameter, and torque the retention mechanism according to the machine manufacturer specifications. Inspect the cutting edges and shank for damage before each use, and never exceed the machine's rated spindle speed for the tool diameter and material combination.
