Accupro 14788688 Ball End Mill 7/8 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 14788688 is a single-end ball end mill designed for precision milling in ferrous and hard materials. It features a 7/8 inch (0.8750 inch) diameter cutting head, a 1-3/4 inch length of cut, and a 4-flute solid carbide construction. The AlTiN+ coating provides high heat resistance and improved tool life at elevated cutting speeds. With an overall length of 4 inches and a matching 7/8 inch straight-cylindrical shank, this end mill is suited for machinists and tool-and-die professionals working on CNC machining centers and manual mills.

This ball end mill is used in applications requiring contoured, profiled, or slotted cuts in steel, stainless steel, cast iron, and similarly hard workpiece materials. The medium helix style balances chip evacuation with cutting stability, making it appropriate for both roughing and finishing passes in 3-axis and multi-axis CNC setups. The 4-flute configuration supports higher feed rates in rigid setups where chip clearance is not a limiting factor.

Key Features

• 7/8 inch cutting diameter with 0.8750 inch decimal precision for consistent fitment in standard toolholders
• AlTiN+ coating for extended tool life and thermal resistance in dry or minimal-lubrication cutting
• 4-flute geometry supports higher feed rates in rigid CNC applications
• 1-3/4 inch length of cut accommodates moderate-depth profiling and contouring operations
• Solid carbide construction provides rigidity and wear resistance compared to HSS alternatives
• Medium helix style balances chip flow and radial cutting forces

Compatibility

Designed as a direct-fit replacement or standard tooling option for CNC machining centers and manual milling machines accepting a 7/8 inch straight-cylindrical shank with ER, Weldon, or equivalent collet-style toolholders.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank fully in a clean, undamaged toolholder to the minimum insertion depth recommended by the holder manufacturer. Verify runout with a dial indicator before commencing a cut. Always power down and lock out the spindle before changing tooling.
