Accupro 12183983 Ball End Mill 0.315 in 2 Flute Carbide

Product Description

The ACCUPRO 12183983 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.315-inch (8 mm) mill diameter and a 2-flute configuration, this single-end tool delivers efficient chip evacuation and a smooth ball-nose profile suited for contour milling, slotting, and 3D profiling. The 40-degree helix angle promotes aggressive cutting action while reducing chatter. Micrograin carbide construction provides hardness and edge retention beyond what standard carbide grades offer. This tool is intended for use by machinists and tooling professionals working on CNC machining centers and manual mills.

This end mill is well suited for die and mold work, profiling complex curved surfaces, and finish passes on hardened or abrasive workpieces. The uncoated finish makes it a straightforward choice for aluminum, copper, and other non-ferrous applications where coating adhesion is less critical. The 8 mm shank diameter is compatible with standard ER collet chucks and end mill holders commonly found in vertical and horizontal machining centers. Right-hand cut and right-hand flute orientation is the industry-standard configuration for the majority of CNC setups.

Key Features

• 0.315-inch (8 mm) ball nose diameter for accurate contour and profile milling
• Micrograin solid carbide construction for superior edge retention and rigidity
• 40-degree helix angle reduces cutting forces and minimizes vibration
• 2-flute spiral design promotes chip clearance in slotting and profiling cuts
• Uncoated finish suits aluminum, copper, and other non-ferrous materials
• Single-end configuration with right-hand cut and right-hand flute direction

Compatibility

Designed for use with standard 8 mm ER collet chucks and end mill holders on CNC machining centers and manual vertical mills. No specific model compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist familiar with CNC tooling setup and runout verification. Power down and lock out the spindle before loading or removing the tool. Confirm collet chuck bore size matches the 8 mm shank before tightening. Check tool runout with a dial indicator after installation to ensure concentricity and prevent premature edge wear.
