Frequently Asked Questions

What is the OSG 700-1250 countersink used for?

The OSG 700-1250 is a 60° single-flute carbide countersink used to create chamfered holes for screw heads in metal, plastic, and composite materials. It is common in aerospace, automotive, and general machining applications where precise countersinking is required.

What are the specifications of the OSG 700-1250 countersink?

The OSG 700-1250 has a 60° included angle, 1 flute, 1/8 in body diameter, and 1/8 in shank diameter. It is made of carbide for wear resistance and is designed for fast cutting. The manufacturer part number is 700-1250.

Where to buy the OSG 700-1250 countersink worldwide?

You can source the OSG 700-1250 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.

How to select the correct OSG countersink for your application?

Select an OSG countersink based on the required chamfer angle (e.g., 60° for standard screw heads), material hardness (carbide for steel), and shank size to match your tool holder. For the 700-1250, ensure your drill or mill accepts a 1/8 in shank.
