Accupro 315054 Square End Mill 1 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 315054 is a single-end, square-profile solid carbide end mill built for demanding milling operations in ferrous and non-ferrous materials. It carries a 1 inch cutting diameter, a 1-1/4 inch length of cut, and a 5 inch overall length, with a matching 1 inch straight shank. The 37-degree helix angle promotes efficient chip evacuation and smooth cutting action. A ZrN (zirconium nitride) coating adds surface hardness and heat resistance, extending tool life in abrasive or high-speed applications. The micrograin carbide substrate supports sharp edge retention. This tool is designed for use in CNC machining centers and manual milling equipment.

This end mill suits production and toolroom environments where close-tolerance profiling, slotting, and peripheral milling are required. Its three-flute geometry balances chip load capacity with flute volume, making it well-suited for moderate to aggressive material removal rates. The right-hand cut and right-hand spiral flute direction are standard for conventional CNC spindle configurations. Centercutting capability allows direct plunge entry without a pre-drilled start hole.

Key Features

• 1 inch cutting diameter with a mill diameter tolerance of +0.000 / -0.005 inches
• 1-1/4 inch length of cut within a 1.25 to 1.50 inch length-of-cut range
• 37-degree helix angle for efficient chip evacuation and reduced cutting forces
• ZrN coating for improved heat resistance and extended tool life
• Micrograin solid carbide substrate for sharp, durable cutting edges
• Centercutting design supports direct plunge entry

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and milling machines accepting a 1 inch straight shank, right-hand spindle configuration.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Verify that the tool holder bore and collet are clean and within tolerance before seating the shank to the specified depth. Confirm spindle direction is right-hand before operation. Follow shop safety protocols and machine manufacturer guidelines for tool change procedures, including ensuring the spindle is fully stopped and the machine is in a safe state before handling.
