Accupro 315093 Square End Mill 1 in 3 Flute Solid Carbide Zrn

Product Description

The ACCUPRO 315093 is a single-end, square-profile solid carbide end mill designed for precision milling in ferrous and non-ferrous materials. It features a 1-inch cutting diameter, a 3-1/2-inch length of cut, and three right-hand spiral flutes with a 37-degree helix angle. A zirconium nitride (ZrN) coating provides added wear resistance and heat reduction at the cutting edge. The micrograin carbide substrate supports tighter tolerances and longer tool life compared to standard carbide grades. This tool is suited for machinists and toolroom operators running CNC or manual milling machines where extended reach and high material removal are required.

This end mill is well matched to slot milling, profiling, and deep-cavity work where a 3-1/2-inch length of cut is needed without a full extended-reach configuration. Right-hand cutting direction and right-hand flute geometry make it compatible with standard spindle rotation on vertical and horizontal milling machines. The single-end design is common in production and job-shop environments where tool replacement is straightforward. It is appropriate for cutting aluminum, steel, stainless steel, and other materials within the capability range of ZrN-coated micrograin carbide tooling.

Key Features

• 1-inch cutting diameter with a tight mill diameter tolerance of +0.000 / -0.005 inches
• 3-1/2-inch length of cut supports deep-slot and deep-profile operations
• 3-flute, right-hand spiral geometry with a 37-degree helix angle for efficient chip evacuation
• ZrN (zirconium nitride) coating improves wear resistance and reduces heat buildup
• Micrograin solid carbide substrate for dimensional stability and edge integrity
• Centercutting design allows plunge entry directly into the workpiece

Compatibility

Designed as a standard 1-inch shank square end mill compatible with collet chucks, milling chucks, and end mill holders sized for a 1-inch shank on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked before inserting or removing the tool from the holder. Use a properly sized collet or end mill holder and verify runout with a dial indicator before beginning a cut. Refer to the tooling manufacturer's recommended speeds and feeds for the specific workpiece material and depth of cut.
