Accupro 313063 Square End Mill 1/4 in 2 Flute Carbide

Product Description

The ACCUPRO 313063 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 1/4 inch cutting diameter and a 1-1/8 inch length of cut, this two-flute tool delivers clean, square-shoulder cuts in a variety of workpiece materials. The 45-degree right-hand helix promotes efficient chip evacuation and reduces heat buildup during cuts. A micrograin carbide grade provides the hardness and edge retention needed for demanding milling applications. Machinists and tool-and-die professionals specify this end mill for profiling, slotting, and peripheral milling.

The 313063 suits light-to-medium-duty milling in ferrous and non-ferrous materials. The bright, uncoated finish makes it a practical choice for applications where coating buildup could interfere with dimensional accuracy or where re-grinding is planned. The 1/4 inch shank diameter fits standard ER and collet chuck toolholders common on CNC machining centers and manual knee mills. The single-end configuration and 2-1/2 inch overall length keep it compact and rigid in the spindle.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• 45-degree right-hand helix for efficient chip evacuation during cuts
• Center-cutting geometry allows plunge entry as well as peripheral milling
• Bright, uncoated finish suitable for aluminum, brass, and applications where re-grinding is anticipated
• Right-hand cutting direction compatible with standard CNC and manual milling spindles
• Two-flute design provides chip clearance in softer or gummier materials

Compatibility

Designed for use with standard 1/4 inch collet chucks and ER-style toolholders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholder specifications. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the end mill. Seat the shank fully within the collet to the minimum insertion depth recommended by the toolholder manufacturer to avoid chatter and runout. Verify collet nut torque and runout with a dial indicator before commencing the cut.
