Accupro 12181287 Square End Mill 0.1772 in 2 Flute Carbide

Product Description

The ACCUPRO 12181287 is a solid carbide square end mill designed for precision milling operations in metal, composite, and hard plastic materials. With a 0.1772-inch (4.50 mm) mill diameter and a 0.6299-inch (16.00 mm) length of cut, this two-flute tool is built for slot milling, profiling, and light pocketing where tight tolerances are required. The micrograin carbide construction provides hardness and wear resistance suited to demanding cutting conditions. Machinists and tool-and-die professionals use this end mill in CNC machining centers and manual mills where consistent edge geometry and dimensional accuracy matter.

This end mill is suited for small-diameter work in a range of shop environments including job shops, precision machining houses, and maintenance toolrooms. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces, making it a practical choice for finishing passes and detail work in tight geometries. The 6.00 mm shank diameter fits standard collet toolholders commonly found on vertical and horizontal machining centers. The uncoated finish makes it appropriate for applications where coating buildup or heat sensitivity is a concern, and for materials where bare carbide performs reliably.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• 2-flute, centercutting design allows plunge entry and slot milling
• 40-degree spiral helix angle promotes chip flow and reduces cutting resistance
• Right-hand cut and right-hand flute orientation for standard CNC and manual mill use
• Uncoated finish suitable for applications requiring bare carbide cutting edges
• Mill diameter tolerance of +0.000 / -0.002 inches for precise fit in close-tolerance work

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool for standard collet toolholding systems accepting a 6.00 mm shank diameter in CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer torque and runout specifications. Ensure the collet and toolholder are clean and free of chips before seating the shank. Confirm spindle speed and feed rate are set to values appropriate for the workpiece material and tool diameter before engaging the cut. Never exceed the tool manufacturer recommended depth of cut for the given diameter.
