Accupro 12183968 Ball End Mill 0.2656 in 2 Flute Carbide

Product Description

The ACCUPRO 12183968 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.2656-inch (17/64-inch) mill diameter and a 0.75-inch length of cut, this tool delivers controlled material removal in profiling, contouring, and slotting applications. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides edge rigidity and wear resistance across a range of workpiece materials. This tool is installed and operated by machinists and CNC programmers in job shop, tool room, and production environments.

This ball end mill is suited for 3-axis and multi-axis CNC machining centers as well as manual milling machines. The 5/16-inch shank diameter fits standard collet chucks and end mill holders. It is appropriate for finish profiling, die and mold work, and complex contour milling where a full-radius tip is required. The uncoated finish makes it a general-purpose option where coated tooling is not required or where re-sharpening is anticipated. The single-end configuration is standard for this diameter class.

Key Features

• Solid micrograin carbide construction for edge strength and dimensional stability
• 0.2656-inch (17/64-inch) ball nose diameter for precise radius profiling
• 40-degree right-hand spiral helix for efficient chip evacuation
• 2-flute configuration suited for slotting and contouring in a range of materials
• Uncoated finish compatible with re-sharpening services
• Mill diameter tolerance of +0.000 to -0.002 inches for consistent fitment

Compatibility

Designed as an OEM-style cutting tool for use in standard 5/16-inch collet chucks and end mill holders on CNC machining centers and manual milling machines requiring a ball nose end mill in the 17/64-inch diameter class.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for toolholder torque and runout specifications. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify shank seating depth and runout with a dial indicator before commencing a cut. Proper speeds and feeds should be calculated based on workpiece material, depth of cut, and machine rigidity.
