Accupro 313333 Square End Mill 1/2 in 2 Flute Carbide

Product Description

The ACCUPRO 313333 is a solid carbide square end mill designed for precision milling operations in metal, composites, and engineered materials. With a 1/2 inch cutting diameter, 2-inch length of cut (LOC), and a 45-degree helix angle, this end mill delivers efficient chip evacuation and stable cutting performance in demanding applications. The 2-flute configuration makes it well suited for slotting and profiling in materials where chip clearance is a priority. Micrograin carbide construction provides hardness and edge retention beyond what standard carbide grades offer. The bright/uncoated finish keeps the tool ready for use as delivered, with no coating buildup to affect tolerances.

This end mill is used in CNC machining centers and manual mills for roughing and finishing passes in ferrous and non-ferrous metals, aluminum, and similar workpiece materials. The long-length configuration, with a 4-inch overall length and 1/2 inch shank diameter, provides reach for deeper pocket milling and cavity work where standard-length tools cannot access the cut zone. Right-hand cutting and right-hand flute direction are standard for conventional CNC spindle setups. Single-end design means the tool is replaced rather than reversed when worn.

Key Features

• 1/2 inch cutting diameter with plus 0.000 / minus 0.002 inch mill diameter tolerance for controlled fitment
• Micrograin solid carbide construction for superior hardness and edge retention
• 45-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• 2-flute geometry optimized for slotting and profiling with maximum chip clearance
• Right-hand cut and right-hand spiral flute direction, compatible with standard CNC spindle rotation
• Bright/uncoated finish — no post-coating dimensional variation
• Center-cutting capable, allowing plunge entry into the workpiece

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting 1/2 inch shank end mills with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. The machine spindle must be fully stopped and the machine powered down or placed in a safe lockout state before changing tooling. Use a calibrated torque-rated tool holder and collet appropriate for a 1/2 inch shank. Verify runout with a dial indicator after seating the tool before initiating a cut. Shank diameter tolerance is plus 0.0001 / minus 0.0004 inch — select a collet or chuck rated for that tolerance range.
