Accupro 12184273 Ball End Mill 1 in 2 Flute Altin Solid Carbide

Product Description

The ACCUPRO 12184273 is a single-end ball end mill designed for high-performance milling in demanding machining environments. Built from micrograin solid carbide, it delivers rigidity and wear resistance across a range of workpiece materials. The 1-inch diameter cutting head features 2 spiral flutes with a 40-degree helix angle for efficient chip evacuation and smooth cutting action. An AlTiN coating increases surface hardness and heat resistance at the cutting edge, extending tool life in dry or high-speed milling conditions. With a 2-inch length of cut and 6-inch overall length, this long-reach configuration suits deeper cavity work and contouring operations where shorter tools cannot reach.

This end mill is suited for milling operations in job shops, production machining, and tool-and-die environments. It handles contour milling, profiling, slotting, and 3D surface work in ferrous and non-ferrous metals. The long overall length makes it a practical choice for aerospace, mold, and die components requiring extended reach into deep pockets or complex geometries. Right-hand cut and right-hand flute direction align with conventional CNC machining center setups.

Key Features

• Micrograin solid carbide construction for hardness and edge retention
• AlTiN coating for elevated heat resistance and reduced tool wear in high-speed cutting
• 40-degree helix angle promotes smooth chip flow and reduced cutting forces
• 2-inch length of cut with 6-inch overall length for extended reach applications
• Right-hand cut and right-hand spiral flutes compatible with standard CNC spindle rotation
• Single-end design; 1-inch shank diameter for secure toolholder engagement

Compatibility

Designed for use in CNC machining centers and milling machines with toolholders accepting a 1-inch shank diameter. Consult toolholder specifications to confirm runout tolerance and clamping length before use.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before loading or removing the tool. Use a properly sized collet chuck, shrink-fit holder, or hydraulic holder rated for the 1-inch shank to minimize runout. Confirm tool projection and stick-out length against your setup sheet before starting the cut to avoid deflection or chatter, particularly given the long overall length of this tool.
