Frequently Asked Questions

What is the OSG 700-1251 countersink used for?

The OSG 700-1251 is a fast-cutting single-flute countersink used to create 82° chamfered holes in metal, plastic, or composite workpieces. It is ideal for deburring and preparing holes for flat-head screws in machining, tooling, and general industrial applications.

What are the specifications of the OSG 700-1251 countersink?

The OSG 700-1251 countersink has an 82° included angle, 1 flute, a 1/8 in body diameter, and a 1/8 in shank. It is made of carbide for durability and precision. The manufacturer part number is 700-1251.

Where to buy the OSG 700-1251 countersink worldwide?

3G Electric supplies the OSG 700-1251 countersink worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on this carbide single-flute countersink.

How to select the right OSG countersink for your application?

To select the right OSG countersink, match the included angle (e.g., 82° for flat-head screws) to your fastener, choose body and shank diameters that fit your tool holder, and select carbide for hard materials. OSG single-flute designs provide fast chip evacuation and clean finishes.
