Osg 640-3753 Diamond Pattern Router Bit 3/8 in Solid Carbide

Product Description

The OSG 640-3753 is a solid carbide diamond pattern router bit designed for precision cutting in demanding applications. With a 0.375-inch cutter diameter and a 1-inch length of cut, this end mill-style bit delivers consistent material removal in fiberglass and similar composite materials. The bright, uncoated finish is suited for applications where coating interaction with the workpiece is a concern. At 2.5 inches overall length with a 3/8-inch shank diameter, it mounts securely in standard router collets and CNC tool holders. Cutting direction is right-hand, standard for most rotating spindle setups used in industrial and fabrication environments.

This router bit is intended for use in fiberglass cutting and routing operations, including panel trimming, slot cutting, and edge profiling on composite substrates. The diamond pattern geometry aids chip evacuation and reduces heat buildup during continuous cuts. It is well suited for use in CNC routers, handheld routing equipment, and machining centers where a 3/8-inch shank tooling system is in use. Fabricators, composite panel shops, and specialty contractors working with fiberglass laminates will find this bit appropriate for production and repair-level routing tasks.

Key Features

• Solid carbide construction for rigidity and wear resistance in abrasive materials
• Diamond pattern geometry promotes chip clearance during fiberglass routing
• 0.375-inch cutter diameter with 1-inch length of cut for controlled depth passes
• Bright, uncoated finish maintains dimensional accuracy without coating buildup
• Right-hand cutting direction compatible with standard CNC and handheld routers
• 3/8-inch shank diameter fits common router collet sizes

Compatibility

Designed for use in routing applications involving fiberglass and composite materials. Compatible with CNC routers and handheld routing equipment accepting a 3/8-inch shank diameter tooling system.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or fabrication technician with the spindle fully powered down and locked out. Ensure the collet and collet nut are clean and free of debris before seating the shank to the correct insertion depth. Do not exceed the tool manufacturer's recommended feed and speed parameters for the workpiece material. Eye and respiratory protection are recommended when routing fiberglass due to airborne particulate hazards.
