Accupro 12181893 Square End Mill 1/8 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 12181893 is a solid carbide square end mill designed for high-precision milling operations in ferrous and non-ferrous materials. At 0.125 inches in diameter with a 0.500-inch length of cut and 1.500-inch overall length, this is a compact, tight-tolerance tool suited for finish milling, slotting, and profiling in confined geometries. The TiCN coating reduces friction and extends tool life in harder workpiece materials. A 40-degree helix angle improves chip evacuation and surface finish. This end mill is intended for use by machinists, tool-and-die makers, and CNC operators working on production or prototype work.

This end mill fits standard 1/8-inch collets and toolholders and is appropriate for use on CNC machining centers, manual mills, and high-speed spindles where a small-diameter, short-reach tool is required. The 3-flute geometry balances chip clearance and cutting edge strength, making it well suited for steel, stainless, cast iron, and similar materials where TiCN coating provides a performance advantage. The centercutting design allows plunge cuts in addition to peripheral and slot milling operations.

Key Features

• Solid carbide micrograin substrate for rigidity and wear resistance in demanding materials
• TiCN finish reduces tool-to-chip friction and improves tool life compared to uncoated carbide
• 40-degree spiral helix promotes aggressive chip evacuation and smoother surface finish
• Centercutting design permits plunge milling in addition to slot and profile operations
• Right-hand cut and right-hand flute configuration for standard spindle direction
• Mill diameter tolerance of +0.000 / -0.002 inches ensures consistent fit and dimensional accuracy

Compatibility

Designed for use in 1/8-inch collets and end mill holders on CNC machining centers and manual knee mills. No specific machine or system compatibility data was provided by the manufacturer for this part number.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out state per applicable shop safety procedures. Seat the shank fully into a clean, undamaged collet or end mill holder and torque the retaining nut according to the toolholder manufacturer specifications. Inspect the cutting edges and coating for chips or wear before each use. Do not exceed the recommended speeds and feeds for the workpiece material and tool diameter.
