The OSG 640-5001 is a solid carbide diamond pattern router bit designed for cutting and trimming fiberglass composite materials. With a 0.5 inch cutter diameter and a 1 inch length of cut, this bit delivers controlled material removal in routing applications where surface integrity and edge quality matter. The bright, uncoated finish maintains dimensional accuracy out of the box. A 0.5 inch shank diameter provides a secure grip in standard collet chucks, and the 2.5 inch overall length suits most handheld and CNC router setups. This bit is typically installed and used by composite fabricators, marine technicians, and industrial tradespeople working with fiberglass laminates and panels.
The OSG 640-5001 is suited for right-hand cutting applications in fiberglass materials, including laminate panels, boat hulls, ductwork reinforcement, and similar composite assemblies. The diamond pattern geometry helps control chip load and reduces edge delamination common in fiberglass routing. It is appropriate for both handheld router applications and CNC routing tables where precise edge profiles are required. The plain end configuration makes it compatible with through-cut and profiling operations without a bottom-cutting requirement.
Designed for use in fiberglass routing applications with routers accepting a 0.5 inch shank collet, including handheld and CNC router platforms.
Installation should be performed by a qualified fabricator or machinist familiar with router tooling. Ensure the router is fully powered down and unplugged before inserting or removing the bit from the collet. Insert the shank to the full recommended depth in the collet and tighten securely per the router manufacturer's torque guidance. When routing fiberglass, use appropriate respiratory protection and eye protection, as fiberglass dust is a known irritant and inhalation hazard.
