The OSG 26501316 is a diamond pattern router bit designed for precision milling and routing operations in solid materials. Built from solid carbide with a diamond coating, this end mill delivers extended tool life and consistent surface finish in demanding applications. The bit measures 0.25 inches in cutter diameter with a 1-inch length of cut and a 3-inch overall length. An 8-flute configuration reduces chip load per flute, allowing smoother cuts and better finish quality in harder materials. The 1/4-inch shank is compatible with standard collet systems found on CNC routers and manual routing equipment.
This router bit is suited for woodworking shops, sign-making operations, composite fabrication, and light metalworking where a fine surface finish is required. The diamond pattern geometry and multi-flute design make it a practical choice for finish passes on hardwoods, plastics, and non-ferrous materials. It is typically installed and operated by machinists, CNC operators, or skilled tradespeople working with routing or milling equipment.
Designed as a direct-fit replacement or standard addition for CNC routers and manual routing machines equipped with 1/4-inch collet systems.
This bit is installed by a machinist or CNC operator. Always power down and lock out the spindle before changing tooling. Verify collet size and torque the collet nut to the router or spindle manufacturer specifications before operation. Inspect the bit for chips or cracks before each use and replace if any damage is visible.
