Accupro 12183973 Ball End Mill 0.276 in 2 Flute Carbide Altin

Product Description

The ACCUPRO 12183973 is a single-end ball end mill designed for precision milling of contoured surfaces, 3D profiles, and complex geometries. Built from solid micrograin carbide, it delivers the rigidity and edge retention required for demanding cutting operations in ferrous and non-ferrous materials. The tool features a 0.276 inch (7 mm) mill diameter, a 0.748 inch (19 mm) length of cut, and an AlTiN coating that improves heat resistance and extends tool life at elevated cutting speeds. With a 40-degree helix angle and right-hand cutting direction, it is suited for high-efficiency finishing and semi-finishing passes on machining centers and CNC mills.

This ball end mill is intended for use in precision machining environments including tool and die shops, aerospace component manufacturing, mold making, and general CNC production work. It accepts a standard 8 mm shank diameter, making it compatible with common ER collet systems and shrink-fit holders. The 63 mm overall length provides adequate reach for most shallow-to-medium-depth cavity work without sacrificing stiffness. It is a single-end tool, so the full length of cut is available from one end only.

Key Features

• Solid micrograin carbide construction for superior edge retention and wear resistance
• AlTiN coating provides thermal barrier for dry or high-speed cutting applications
• 40-degree right-hand spiral helix promotes efficient chip evacuation
• 0.276 inch (7 mm) ball diameter for contour milling and 3D profile work
• 8 mm shank diameter fits standard ER collet chucks and shrink-fit toolholders
• Single-end design with 0.748 inch length of cut and 63 mm overall length

Compatibility

Designed as a standard single-end ball end mill with an 8 mm shank diameter; compatible with CNC machining centers and manual mills equipped with ER collet systems or other 8 mm bore toolholders.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention nut per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout will accelerate tool wear and degrade surface finish.
