Accupro 14788583 Square End Mill 1/4 Inch 4 Flute Carbide

Product Description

The ACCUPRO 14788583 is a solid carbide square end mill designed for precise milling operations in metalworking and machining environments. With a 1/4 inch (0.2500 inch) mill diameter and 4 helical flutes, this end mill delivers efficient chip evacuation and a clean square shoulder profile. The centercutting geometry allows direct plunge entry into workpiece material without pre-drilling a pilot hole. An overall length of 6 inches provides extended reach capability for deeper setups. This tool is primarily installed and operated by machinists and CNC operators in production and job-shop environments.

This end mill is suited for a wide range of milling applications including slotting, profiling, and peripheral milling on ferrous and non-ferrous materials. The 1-1/2 inch length of cut accommodates moderate-depth passes, while the cylindrical shank fits standard collets and end mill holders with a 1/4 inch bore. It is a practical choice for CNC machining centers and manual knee mills requiring a general-purpose square-profile carbide tool.

Key Features

• Solid carbide construction for hardness and heat resistance in demanding cuts
• 4 helical flutes promote efficient chip removal and smooth surface finish
• Centercutting design enables direct plunge milling without a pilot hole
• 1/4 inch cylindrical shank fits standard 1/4 inch collets and tool holders
• 1-1/2 inch length of cut supports moderate-depth slotting and profiling passes
• 6 inch overall length allows reach into deeper workpiece features

Compatibility

Designed as a direct-fit replacement for standard 1/4 inch square end mill applications using cylindrical-shank collet holders and end mill holders with a 1/4 inch bore capacity.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before changing tooling. Seat the cylindrical shank fully into the collet or holder and torque the retention hardware per the tool holder manufacturer guidelines. Verify runout with a dial indicator before beginning production cuts.
