Accupro 12178962 Square End Mill 1 Inch 4 Flute Carbide

Product Description

The ACCUPRO 12178962 is a solid carbide square end mill designed for precision milling in metal-cutting applications. With a 1 inch cutting diameter, 4 spiral flutes, and a 40-degree helix angle, this tool delivers efficient chip evacuation and smooth cutting action in ferrous and non-ferrous materials. The nACRo coating provides enhanced wear resistance and thermal stability at elevated cutting speeds. The micrograin carbide substrate offers the toughness and edge retention required for demanding production environments. Licensed machinists and CNC operators working in job shops, aerospace, and general manufacturing will find this tool suited to slotting, profiling, and peripheral milling operations.

This end mill is built for use in CNC machining centers and manual mills where a 1 inch shank and 4 inch overall length are appropriate. The 1-3/4 inch length of cut supports moderate-depth passes in steel, stainless, cast iron, and similar materials. The centercutting geometry allows plunge entry, giving operators flexibility when programming tool paths that require direct Z-axis engagement. The right-hand cut and right-hand spiral flute configuration is the standard orientation for the majority of vertical machining center spindles in production use.

Key Features

• Solid micrograin carbide construction for superior edge retention and rigidity
• nACRo finish for extended tool life and improved performance in hard materials
• 40-degree helix angle promotes efficient chip flow and reduces cutting forces
• Centercutting design allows direct plunge entry into workpiece
• Right-hand cut, right-hand flute — standard orientation for CNC vertical mills
• No chipbreaker on flutes for clean, continuous cuts in profiling applications

Compatibility

Designed as a standard 1 inch shank square end mill compatible with ER, CAT, BT, and HSK toolholders sized for 1 inch collets or end mill holders on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in an energy-isolated state before changing tooling. Use a properly sized end mill holder or collet chuck with adequate pull-out force for the shank diameter — confirm runout with a dial indicator after seating. Follow machine tool manufacturer torque specifications for drawbar or retention knob tightening.
