Accupro 315346 Ball End Mill 1 in 3 Flute Solid Carbide Zrn

Product Description

The ACCUPRO 315346 is a single-end ball end mill designed for contour milling, profiling, and 3D surface work in metalworking and machining applications. It is ground from micrograin solid carbide for rigidity and edge retention, and carries a ZrN (zirconium nitride) coating that reduces friction and extends tool life in ferrous and non-ferrous materials. The mill measures 1 inch in diameter with a 2 inch length of cut and a 5 inch overall length. The 37-degree helix angle promotes efficient chip evacuation, and the three-flute geometry balances material removal rate with surface finish quality. Installed by machinists and CNC operators on vertical and horizontal machining centers.

This end mill is suited for medium to high-speed finishing and semi-finishing passes on molds, dies, and complex contoured parts. The 1 inch shank diameter provides a secure grip in standard ER or side-lock toolholders. The right-hand cut and right-hand spiral flute direction are standard for the majority of CNC milling setups. The ZrN coating makes this tool a practical choice when running aluminum, stainless, alloy steels, and hardened materials where heat and built-up edge are concerns.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• ZrN coating reduces friction and extends tool life across a range of workpiece materials
• 37-degree helix angle promotes aggressive chip evacuation and smooth cutting action
• 3-flute design balances cutting efficiency with finish quality on contoured surfaces
• Single-end configuration with right-hand cut and right-hand spiral
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit and dimensional accuracy

Compatibility

Designed as a standard 1 inch shank ball end mill compatible with ER collet chucks, side-lock holders, and shrink-fit toolholders sized for 1 inch straight shanks on CNC vertical and horizontal machining centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Always power down and lock out the spindle before changing tooling. Ensure the shank is fully seated to the recommended gauge line in the toolholder and that holder runout is verified before cutting. Consult the machine tool manufacturer specifications and applicable shop safety procedures when setting speeds and feeds for carbide tooling.
