Accupro 14788659 Ball End Mill 1 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 14788659 is a solid carbide ball end mill designed for high-performance milling operations in ferrous and non-ferrous materials. With a 1-inch cutting diameter and a 3-inch length of cut, this tool handles deep-cavity profiling, contouring, and 3D surface work. The AlTiN+ coating provides elevated heat resistance and extended tool life under aggressive cutting conditions. Three medium-style flutes balance chip evacuation with rigidity, making it well suited for hardened steels, stainless alloys, and titanium. Machinists and tooling specialists running CNC machining centers will find this end mill appropriate for high-feed finishing and semi-finishing passes where surface integrity and dimensional accuracy matter.

This ball end mill is used in precision machining environments including job shops, aerospace fabrication, mold and die work, and general CNC production. The 1-inch shank diameter and 6-inch overall length allow reach into deep pockets and complex contoured geometry without requiring extended-reach toolholders in most standard setups. The cylindrical shank is compatible with ER collet chucks, Weldon-style holders, and shrink-fit systems. The AlTiN+ coating makes it particularly effective in dry or near-dry cutting applications where coolant use is limited or controlled.

Key Features

• 1-inch ball nose cutting diameter for contouring and 3D surface profiling
• 3-inch length of cut for deep-cavity and deep-pocket milling
• AlTiN+ coating for high heat resistance and extended tool life in hard materials
• 3-flute medium flute geometry balances chip clearance and cutting stability
• Solid carbide construction provides rigidity and dimensional consistency
• Cylindrical shank with 1-inch diameter for broad toolholder compatibility

Compatibility

Designed for use in CNC machining centers and milling machines accepting a 1-inch cylindrical shank. Compatible with standard ER collet chucks, shrink-fit holders, and Weldon-style toolholders sized for 1-inch shanks.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with CNC toolholder setup procedures. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Verify runout after seating the shank in the holder, as excessive runout accelerates wear on a solid carbide tool and reduces surface finish quality. Torque toolholder fasteners according to the toolholder manufacturer specifications only.
