Osg 640-2501 Diamond Pattern Router Bit 0.25in Carbide

Product Description

The OSG 640-2501 is a solid carbide diamond pattern router bit designed for cutting and routing fiberglass materials. It features a 0.25-inch cutter diameter, a 0.75-inch length of cut, and a 2.0-inch overall length, making it well suited for precise work in composite and fiberglass panel applications. The bright, uncoated finish is standard for solid carbide tooling used in abrasive non-metallic materials. A 1/4-inch shank diameter provides compatibility with common router collets found in handheld routers and CNC routing spindles. This bit is typically installed and operated by machinists, fabricators, and composite specialists working with fiberglass laminates.

This router bit is intended for use in fiberglass cutting and routing operations, including trimming, slotting, and profiling fiberglass panels and laminates. The diamond pattern geometry aids in chip evacuation and edge quality when working through abrasive composite materials. It is appropriate for both manual routing setups and CNC router applications where a 1/4-inch collet is used. Right-hand cutting direction is standard for conventional router spindle rotation. No end cutting geometry is present, so plunge entry is not supported with this configuration.

Key Features

• Solid carbide construction for durability in abrasive fiberglass applications
• Diamond pattern flute geometry promotes chip clearance and clean edge finish
• 0.75-inch length of cut supports shallow-to-moderate depth routing passes
• Bright, uncoated finish standard for solid carbide composite tooling
• Right-hand cutting direction for standard router spindle rotation
• Plain end type — no end cutting; not designed for plunge entry

Compatibility

Designed for use in routers equipped with a 1/4-inch collet; material application is fiberglass as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or fabricator familiar with router tooling and composite materials. Secure the shank fully into the collet per the router manufacturer's minimum insertion depth requirement before operation. Always power down and lock out the router before changing or inspecting bits. Eye protection and appropriate respiratory protection are required when routing fiberglass due to airborne particulate hazards.
