Accupro 313584 Ball End Mill 1/4 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 313584 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. It features a 1/4 inch diameter cutting head with a 3/8 inch length of cut and a 45-degree helix angle, which promotes efficient chip evacuation and smooth cutting action. The two-flute geometry suits slotting, profiling, and 3D contouring work where chip clearance is a priority. Manufactured from micrograin solid carbide, this tool delivers the rigidity and edge retention required for ferrous and non-ferrous materials. The bright, uncoated finish makes it straightforward to inspect for wear during use.

This end mill fits standard CNC machining centers and manual mills equipped with a 1/4 inch collet or toolholder. It is a single-end, right-hand cut tool with right-hand flute direction, making it compatible with conventional spindle rotation on most vertical and horizontal milling setups. Typical applications include die and mold work, contour milling, and finish passes on aluminum, steel, and similar materials where a ball nose profile is required to generate radiused surfaces or complex 3D geometry.

Key Features

• Micrograin solid carbide construction for high edge retention and rigidity
• 1/4 inch cutting diameter with 3/8 inch length of cut
• 45-degree helix angle promotes efficient chip evacuation
• 2-flute design suited for slotting, profiling, and 3D contouring
• Bright, uncoated finish — no coating buildup to affect tolerance
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit

Compatibility

Designed as a direct-fit replacement or standard addition for CNC machining centers and manual mills using a 1/4 inch collet or toolholder with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully powered down and the machine is locked out before changing tooling. Seat the 1/4 inch shank fully and evenly in a clean, undamaged collet or toolholder, and torque the retention nut to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a cut to protect both the tool and the workpiece.
