Frequently Asked Questions

What is the OSG 700-3751 countersink used for?

The OSG 700-3751 is a fast-cutting single-flute countersink designed for deburring and chamfering holes in metal, plastic, and composite materials. Its 82° included angle matches standard flat-head screw angles, making it ideal for aerospace, automotive, and general machining applications where precise countersinking is required.

What are the specifications of the OSG 700-3751 countersink?

The OSG 700-3751 countersink has a 3/8 in body diameter, a single flute, and an 82° included angle. It is made from carbide for durability and wear resistance. The manufacturer part number is 700-3751, and it is designed for fast cutting in ferrous and non-ferrous materials.

Where to buy the OSG 700-3751 countersink worldwide?

You can source the OSG 700-3751 countersink through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply this OSG carbide countersink to procurement teams and plant engineers internationally.

How to select the right OSG countersink for your application?

To select the correct OSG countersink, match the included angle to your fastener (e.g., 82° for standard flat-head screws). Choose a body diameter slightly larger than the screw head. For hard materials like stainless steel, opt for carbide tools like the 700-3751. Single-flute designs provide fast chip evacuation and smooth finishes.
