Accupro 14788479 Square End Mill 4 Flute Solid Carbide

Product Description

The ACCUPRO 14788479 is a solid carbide square end mill designed for precise milling operations in metal, composites, and hard materials. Built with four helical flutes and a centercutting geometry, it can plunge directly into workpieces as well as perform peripheral and slot milling. The 7mm mill diameter pairs with a 19mm length of cut and an 8mm cylindrical shank, giving machinists a rigid, accurate tool suited for finishing and light roughing passes in CNC machining centers and manual mills. The helix angle falls in the 38 to 42 degree range, promoting efficient chip evacuation and reduced cutting forces at the tool tip.

This end mill is intended for use in precision machining environments including tool shops, production floors, and job shops running CNC or manual milling equipment. Its centercutting capability makes it suitable for drilling entry points and full-slot cuts without requiring a pilot hole. The solid carbide construction handles the elevated temperatures and cutting forces common in ferrous and non-ferrous machining applications. Machinists working on close-tolerance features, contour milling, or pocket clearing will find the 7mm diameter and 19mm cut length well matched to small-feature work.

Key Features

• Centercutting geometry allows direct plunge entry without a pre-drilled hole
• Four helical flutes for balanced chip load and smooth surface finish
• Helix angle of 38 to 42 degrees promotes efficient chip evacuation
• Solid carbide construction for rigidity and wear resistance in demanding materials
• Cylindrical shank compatible with standard ER collet chucks and end mill holders
• No chipbreaker design suited for finishing and semi-finishing passes

Compatibility

Designed as an OEM-style replacement solid carbide end mill for use in standard ER collet or end mill holder setups accepting an 8mm cylindrical shank.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the cylindrical shank fully in the collet or holder and tighten to the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning cuts to protect both the tool and the workpiece.
