Frequently Asked Questions

What is the OSG 700-3752 countersink used for?

The OSG 700-3752 is a 90° single-flute carbide countersink used for deburring and chamfering holes in metal, plastic, and composite materials. Its fast-cutting design suits high-production machining, aerospace, and automotive applications where precision and surface finish matter.

What are the specifications of the OSG 700-3752 countersink?

The OSG 700-3752 is a 90° countersink with 1 flute and a 3/8 in body diameter. It is made of carbide for wear resistance and long tool life. The manufacturer part number is 700-3752. This single-flute design provides fast, chatter-free cutting in ferrous and non-ferrous materials.

Where to buy the OSG 700-3752 countersink worldwide?

3G Electric supplies the OSG 700-3752 countersink worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this carbide single-flute countersink.

How to select the right OSG countersink for your application?

Select an OSG countersink based on hole angle (e.g., 90° for standard flathead screws), material (carbide for hard metals), and flute count (single-flute for fast cutting). Match body diameter to your toolholder. For the 700-3752, use with a 3/8 in collet or chuck.
