OSG 700-3751 Fast-Cutting Single-Flute Countersink

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.

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.

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.

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.
