Accupro 14881863 Ball End Mill 1/4 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 14881863 is a solid carbide ball end mill designed for precision milling in demanding machining applications. Built to miniature-series tolerances, this single-end tool features a 1/4 inch mill diameter, a 3/8 inch length of cut, and a 6 inch overall length. The micrograin carbide construction delivers rigidity and wear resistance for consistent performance in ferrous and non-ferrous materials. With a 30-degree helix angle and a chipbreaker geometry across its 3 spiral flutes, it is suited for high-precision contouring, slotting, and profiling operations. The bright/uncoated finish makes it straightforward to inspect for wear.

This ball end mill is intended for use on CNC machining centers and manual mills requiring a miniature-series tool with extended reach capability. The 1/4 inch shank diameter matches standard ER collet and end mill holder tooling. It is well-suited for die and mold work, aerospace components, and intricate part features where a tight mill diameter tolerance of +0.0000/-0.0010 inches is required. Machinists working in tool rooms, production shops, and job shops will find this tool appropriate for finish milling contoured surfaces and tight-tolerance pockets.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• 3 spiral flutes with chipbreaker geometry for efficient chip evacuation
• 30-degree helix angle supports smooth cutting action on contoured surfaces
• Extended reach design accommodates deeper cavity and pocket work
• Bright/uncoated finish allows direct visual inspection of cutting edges
• Right-hand cut and right-hand flute direction for standard spindle operation

Compatibility

Designed as an OEM-style miniature-series ball end mill compatible with standard 1/4 inch shank end mill holders and ER collet systems used on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the holder to the recommended gauge line and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial test indicator before beginning a production cut.
