Accupro 12177137 Ball End Mill 1 in 4 Flute Solid Carbide Altin

Product Description

The ACCUPRO 12177137 is a single-end ball end mill designed for precision milling operations in ferrous and hardened materials. Built from micrograin solid carbide and finished with an AlTiN coating, this tool delivers thermal resistance and hardness retention at elevated cutting temperatures. It runs a 4-flute, right-hand spiral configuration with a 40-degree helix angle, balancing chip evacuation with surface finish quality. With a 1 inch cutting diameter and 1.75 inch length of cut, it suits deep-pocket, contour, and 3D profiling work. Machinists and CNC programmers select this tool for high-speed and hard-material applications where tool life and dimensional accuracy are priorities.

The 12177137 is suited for CNC machining centers running ferrous alloys, stainless steels, titanium, and other abrasion-intensive workpiece materials where AlTiN coating performance is advantageous. The 1 inch shank diameter fits standard ER and end mill holders in that bore size. Its 4 inch overall length provides reach for moderate-depth features without excessive tool deflection. This tool is appropriate for job shops, aerospace component machining, and die and mold work where consistent tool geometry is required across a production run.

Key Features

• Micrograin solid carbide substrate for rigidity and wear resistance in hard materials
• AlTiN coating provides oxidation resistance and extends tool life at high cutting temperatures
• 40-degree helix angle balances chip flow and cutting edge stability
• 4-flute, right-hand spiral geometry optimized for finish milling and contouring
• Single-end configuration with matched 1 inch shank and cutting diameter for direct holder compatibility
• No extended reach, variable helix, or variable index — consistent, predictable cutting geometry

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining applications requiring a 1 inch diameter ball end mill with a 1 inch shank in AlTiN-coated solid carbide.

Installation Notes

Installation is performed by qualified machinists or CNC setup personnel. Secure the shank in a properly sized end mill holder or collet chuck and torque to the holder manufacturer's specification. Verify runout with a dial indicator before cutting. Always confirm spindle direction matches the right-hand cutting orientation of this tool before starting the machine.
