Accupro 315333 Ball End Mill 3/4 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 315333 is a single-end ball end mill designed for three-dimensional profiling, contouring, and finish milling in ferrous and non-ferrous materials. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for demanding CNC machining operations. The 3/4-inch mill diameter pairs with a 3-1/4-inch length of cut, giving machinists reach into deep pockets and complex contours. A zirconium nitride (ZrN) coating reduces friction and extends tool life in abrasive materials. The 37-degree right-hand spiral helix promotes efficient chip evacuation and smooth cutting action across a wide range of workpiece materials.

This end mill is suited for vertical and horizontal machining centers running production or prototype work in tool and die, mold making, aerospace components, and general precision machining. The 3/4-inch shank diameter fits standard ER and side-lock toolholders common on most CNC machining centers. With a 6-inch overall length, it accommodates setups requiring extended reach without sacrificing rigidity when properly supported in the toolholder. It is intended for use by machinists and CNC programmers operating production or job-shop equipment.

Key Features

• Micrograin solid carbide construction for high rigidity and long edge life
• ZrN coating reduces friction and improves wear resistance in abrasive cuts
• 37-degree right-hand helix promotes chip evacuation and smooth cutting action
• 3-1/4-inch length of cut enables deep pocket and contour work
• 3 flutes balance chip clearance with surface finish quality
• Single-end design with right-hand cutting direction for standard CNC spindle use

Compatibility

Designed for use in CNC machining centers and mills accepting a 3/4-inch shank diameter toolholder. Suitable for right-hand spindle rotation applications in mold, die, and general precision machining environments.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool changer or spindle is locked out before inserting or removing the end mill from the toolholder. Seat the shank to the minimum recommended insertion depth per the toolholder manufacturer specification to avoid deflection. Verify runout with a dial indicator after toolholder assembly before beginning a cut.
