Accupro 12177283 Ball End Mill 0.0394 in 2 Flute Carbide

Product Description

The ACCUPRO 12177283 is a solid carbide ball end mill designed for precision milling of contoured surfaces, 3D profiles, and fine detail work in ferrous and non-ferrous materials. With a 1.00 mm (0.0394 inch) cutting diameter and a matching 1.00 mm length of cut, this is a micro-geometry tool built for tight-tolerance applications. The 6.00 mm shank provides rigid clamping in standard collets while the extended-reach configuration allows access to deeper features. Micrograin carbide construction delivers the hardness and edge retention needed for high-speed, low-feed micro-milling operations. Installed by machinists and toolroom professionals on CNC machining centers and die/mold equipment.

This end mill is well suited for die and mold work, prototype machining, and detailed finish passes in tight cavities where a standard short-reach tool cannot reach the workpiece. The 30-degree helix angle provides a balance of cutting efficiency and chip evacuation at the small diameters involved. The 0.95 mm neck diameter and 11.00 mm reach length allow the tool to step down into recessed pockets without shank contact. Right-hand cut and right-hand flute direction make it compatible with conventional CNC spindle rotation. Single-end configuration means the tool is replaced rather than reversed when worn.

Key Features

• 1.00 mm (0.0394 inch) ball nose cutting diameter for micro-scale contour and profile milling
• Micrograin solid carbide construction for edge sharpness and wear resistance at high surface speeds
• Extended reach design with 0.95 mm neck diameter and 11.00 mm reach length for deep-cavity access
• 30-degree helix angle balances chip flow and cutting forces at small diameters
• Uncoated finish suited for applications where coating buildup at micro diameters would affect dimensional accuracy
• 6.00 mm shank diameter fits standard ER collet chucks without adapters

Compatibility

Designed as a standard-geometry single-end ball nose end mill with a 6.00 mm shank, compatible with ER-style collet chucks and shrink-fit holders sized for 6 mm shank tooling on CNC milling machines and machining centers.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool builder guidelines for tool clamping torque and runout tolerance. Ensure the collet and holder are clean and free of chips before seating the shank. At this cutting diameter, even minor runout will significantly affect tool life and surface finish, so verify total indicator runout at setup. Do not exceed the manufacturer-specified depth of cut or feed rate for micro-diameter carbide tooling, as overload will cause immediate tool fracture.
