Accupro 12176618 Square End Mill 1 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12176618 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. It features a 1 inch cutting diameter, a 1-1/8 inch length of cut, and a 3 inch overall length with a 1 inch shank diameter. The three-flute spiral geometry runs at a 40-degree helix angle with a zirconium nitride (ZrN) finish, providing good chip evacuation and surface finish on a range of workpiece materials. Centercutting capability allows this tool to plunge directly into a workpiece. The micrograin carbide substrate supports rigidity and edge retention in demanding cuts.

This end mill is suited for stub-length milling operations in CNC machining centers and manual mills. Right-hand cut and right-hand flute orientation make it compatible with standard spindle setups. The ZrN coating is appropriate for use on steels, cast iron, and similar ferrous and non-ferrous materials where heat resistance and lubricity at the cutting edge are priorities. Machinists working in job shops, tool rooms, and production environments will find the three-flute design a practical choice for slotting, profiling, and peripheral milling at 1 inch diameter.

Key Features

• 1 inch cutting diameter with mill diameter tolerance of plus 0.000 / minus 0.002 inches
• Solid micrograin carbide construction for edge retention and rigidity
• ZrN (zirconium nitride) finish for heat resistance and reduced friction at the cutting edge
• 40-degree helix angle with spiral flute geometry for efficient chip evacuation
• Centercutting design allows direct plunge entry into the workpiece
• Right-hand cut, right-hand flute — compatible with standard CNC and manual mill spindles

Compatibility

Designed as a standard-shank square end mill for use in 1 inch collets, end mill holders, and hydraulic or shrink-fit toolholders on CNC machining centers and manual knee mills.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the spindle is fully stopped and locked before inserting or removing the tool from the holder. Verify shank runout and holder cleanliness before clamping; shank diameter tolerance is minus 0.0001 to minus 0.0004 inches and requires a properly sized holder bore for accurate seating. Follow machine manufacturer guidelines and applicable shop safety procedures when setting tool length offsets and cutting parameters.
