Frequently Asked Questions

What is an OSG solid router bit with diamond cut used for?

This OSG solid router bit with diamond cut and plain end is designed for routing composite materials. Its diamond-pattern geometry reduces delamination and provides a clean finish in carbon fiber, fiberglass, and other abrasive composites. It is commonly used in aerospace, automotive, and marine manufacturing.

What are the specifications of the OSG 640-3751 router bit?

The OSG 640-3751 is a solid carbide router bit with a diamond cut pattern and plain end. It has a 3/8" cutting diameter and 1" length of cut (LOC). The manufacturer part number is 640-3751. It is designed specifically for routing composite materials to minimize fraying and extend tool life.

How to select the correct OSG router bit for composites?

Select an OSG router bit based on material type and cut quality needed. For composites like carbon fiber, a diamond-cut pattern (as on the 640-3751) reduces edge chipping. Match cutting diameter and length of cut to your application depth. Use proper feed rates and cooling to extend tool life.
