Accupro 312948 Square End Mill 5/32 in 2 Flute Carbide Zrn

Product Description

The ACCUPRO 312948 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide and coated with zirconium nitride (ZrN), it delivers hardness and heat resistance suited to ferrous and non-ferrous materials. The 2-flute, 45-degree right-hand spiral geometry promotes efficient chip evacuation and smooth cutting action. At 5/32 inches in diameter with a 5/16 inch length of cut, this is a stub-length tool optimized for rigidity in tight-clearance cuts. Machinists and CNC operators working in job shops, tool rooms, or production environments are the primary users of this tool.

This end mill is suited for slotting, profiling, and peripheral milling operations on a variety of workpiece materials. The ZrN coating extends tool life in abrasive cutting conditions. The stub-length design reduces deflection, making it a practical choice for short-reach applications where rigidity matters more than extended reach. The 3/16 inch shank diameter fits standard collets and end mill holders on vertical machining centers and manual mills. It is a single-end tool with centercutting capability, allowing plunge entry into workpieces when required.

Key Features

• Micrograin solid carbide construction for durability and edge retention
• ZrN (zirconium nitride) coating for improved wear resistance and heat management
• 45-degree right-hand helix for efficient chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge entry without pre-drilling
• Stub-length geometry minimizes deflection in short-reach milling operations
• Spiral flute type with no chipbreaker for clean, continuous cuts

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 3/16 inch shank diameter in standard collet or end mill holder systems.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The machine spindle must be fully stopped and locked out before mounting or removing the tool. Ensure the collet or tool holder is clean and free of chips before seating the shank. Verify runout with a dial indicator after mounting to confirm proper seating and avoid premature edge wear or workpiece damage.
