Osg 402-0625-BN08 Ball End Mill 0.0625 in 2 Flute Carbide

Product Description

The OSG 402-0625-BN08 is a single-end ball end mill engineered for precision milling in demanding machining environments. Built from micrograin solid carbide, it delivers the hardness and edge retention needed for high-speed finishing passes and contoured surface work. The 0.0625-inch diameter cutting head is paired with a TiCN (Titanium Carbonitride) coating that improves wear resistance and reduces built-up edge on ferrous and non-ferrous materials. With a 2-flute geometry and a 30-degree helix angle, this end mill balances chip evacuation with surface finish quality. It belongs to OSG Series 402BN and is installed by machinists and tool-and-die professionals running CNC mills and machining centers.

This end mill is suited for 3D contouring, slotting, and finish milling operations where a small-diameter ball nose profile is required. The 0.1875-inch length of cut and 1.5-inch overall length make it appropriate for shallow to moderate-depth feature work in mold cavities, dies, and precision components. The right-hand cut and right-hand spiral flute direction are standard for conventional CNC milling setups. It is a regular-length tool intended for close-tolerance work in production and job-shop environments.

Key Features

• Micrograin solid carbide construction for superior hardness and edge stability
• TiCN coating increases surface hardness and extends tool life in abrasive materials
• 30-degree helix angle promotes smooth chip flow and consistent surface finish
• 2-flute ball nose geometry designed for contour and finish milling passes
• Right-hand cut with right-hand spiral flute direction for standard CNC spindle compatibility
• Single-end design in OSG Series 402BN for consistent dimensional repeatability

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and vertical mills accepting a 0.125-inch straight shank end mill.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the 0.125-inch shank in a matching collet or end mill holder and torque to the spindle manufacturer specifications before operation. Verify runout with a dial indicator before cutting to protect the small-diameter carbide cutting edge. Do not exceed the manufacturer recommended feeds and speeds for the workpiece material and coating type.
