Accupro 14788500 Square End Mill 4 Flute Solid Carbide

Product Description

The ACCUPRO 14788500 is a 4-flute solid carbide square end mill designed for precision milling operations in metal removal and finishing applications. Built from solid carbide, it delivers the hardness and wear resistance required for demanding cuts in ferrous and non-ferrous materials. The 20mm mill diameter pairs with a 38mm length of cut to handle both shallow and moderate-depth passes. A helical flute geometry and 38 to 42 degree helix angle promote smooth chip evacuation and reduce cutting forces. Centercutting capability allows direct plunge entry without a pre-drilled hole. This end mill is installed by machinists and tool-and-die professionals working on CNC machining centers and manual mills.

Suited for use on vertical and horizontal milling machines, this end mill performs in general-purpose contouring, slotting, profiling, and peripheral milling. The cylindrical shank seats securely in standard collet chucks and end mill holders with a 20mm bore. With no chipbreaker and no extended reach, this is a straight-duty tool optimized for consistent material removal in production and job-shop environments alike. Its 100mm overall length keeps deflection low during aggressive passes.

Key Features

• Solid carbide construction for high hardness and extended tool life
• 4 helical flutes for efficient chip evacuation and smooth cutting action
• Centercutting design allows direct plunge milling without pilot drilling
• 38 to 42 degree helix angle reduces cutting forces and improves surface finish
• 20mm cylindrical shank for compatibility with standard collet chucks and end mill holders
• 100mm overall length minimizes deflection during full-depth passes

Compatibility

Designed as an OEM-style replacement solid carbide end mill for use in standard 20mm collet chucks, shrink-fit holders, and end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine fully powered down and the spindle at a complete stop. Seat the cylindrical shank fully into the collet or holder and torque the retention hardware according to the holder manufacturer specifications. Inspect the cutting edges for chips or wear before each use. Handle solid carbide tooling with care, as carbide is brittle and susceptible to chipping from impact or improper clamping.
