Accupro 2500141 Square End Mill 1/2 in 3 Flute Carbide

Product Description

The ACCUPRO 2500141 is a solid carbide square end mill designed for high-precision milling operations in metal, composites, and hard materials. It features a 1/2 inch diameter cutting end with a 2 inch length of cut (LOC), making it suitable for deeper pocketing and slotting passes without tool change. The 60-degree helix angle promotes aggressive chip evacuation and reduces heat buildup at the cutting edge. Micrograin carbide construction provides the hardness and edge retention needed for demanding production environments. This is a single-end, right-hand cutting tool with a right-hand spiral flute direction. It is installed and used by machinists and toolroom technicians on CNC machining centers and manual mills.

The 2500141 fits standard 1/2 inch toolholders and collet chucks, making it a practical choice for production shops, job shops, and maintenance machining applications. The long-length classification and 2 inch LOC allow access to deeper features in molds, fixtures, and structural components. The bright uncoated finish suits applications where coating interaction with the workpiece material is a concern, or where regrinding is planned after wear. Three flutes balance chip clearance with cutting edge count, which works well in a range of ferrous and non-ferrous materials.

Key Features

• 1/2 inch mill diameter with plus 0.000 / minus 0.002 inch tolerance for consistent fit and finish
• 2 inch length of cut supports deep pocketing and slot milling in a single pass
• 60-degree helix angle promotes fast chip evacuation and reduces cutting temperature
• Micrograin solid carbide construction delivers edge hardness and wear resistance
• Right-hand cut, right-hand spiral, center-cutting design allows plunge entry
• Bright uncoated finish compatible with regrinding services

Compatibility

Designed for use in standard 1/2 inch collet chucks, end mill holders, and hydraulic toolholders on CNC machining centers and manual knee mills. Shank diameter tolerance of plus 0.0001 / minus 0.0004 inch ensures consistent grip in precision holders.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool. Seat the shank fully into the holder to the minimum insertion depth recommended by the holder manufacturer before torquing set screws or clamping. Inspect the cutting edges and shank for chips or runout with a dial indicator before beginning a new operation.
