Accupro 12179710 Square End Mill 1/4 in 3 Flute Carbide

Product Description

The ACCUPRO 12179710 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.25-inch mill diameter, a 0.75-inch length of cut, and a 2.5-inch overall length, this tool is built for tight-tolerance work in a wide range of materials. The ZrN (zirconium nitride) coating improves surface hardness and lubricity, extending tool life in demanding cuts. Three spiral flutes with a 40-degree helix angle promote efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides the rigidity and edge retention needed for consistent performance across production runs.

This end mill is suited for slotting, profiling, and peripheral milling in ferrous and non-ferrous metals, plastics, and composites. The centercutting geometry allows for plunge entry as well as conventional milling passes. Right-hand cut and right-hand flute configuration match standard CNC machining center and manual mill setups. The regular-length designation makes this a practical choice for general-purpose work where extended reach is not required. Machinists and tool-and-die professionals will find this tool appropriate for both prototype and production environments.

Key Features

• Solid micrograin carbide construction for superior edge retention and rigidity
• ZrN coating improves hardness and reduces friction at the cutting edge
• 40-degree helix angle with spiral flutes for efficient chip evacuation
• Centercutting design supports plunge milling and ramp entry
• Right-hand cut and right-hand flute for standard spindle compatibility
• Mill diameter tolerance of +0.000 / -0.002 inches for precise fitment

Compatibility

Designed as a standard-shank square end mill with a 0.25-inch shank diameter, compatible with collet systems and tool holders sized for 1/4-inch shank tooling on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following the tool holder manufacturer torque and runout specifications. Ensure the shank is fully seated and clamped in the collet or end mill holder before spindle engagement. Confirm spindle direction matches the right-hand cut orientation of this tool before operation. Inspect the cutting edges for chips or damage before each use and replace if edge integrity is compromised.
