Product Description

OSG Fast-Cutting Single-Flute Countersinks.

Frequently Asked Questions

What is the OSG 82° countersink used for?

The OSG 82° single-flute countersink is designed for deburring and countersinking 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 chamfering is required.

What are the specifications of the OSG 700-6251 countersink?

The OSG 700-6251 is a 82° countersink with a single flute and a 5/8 in body diameter. It is made from carbide for durability and high-speed cutting. The manufacturer part number is 700-6251, and it is designed for fast, clean countersinking in ferrous and non-ferrous materials.

Where to buy the OSG 700-6251 countersink worldwide?

3G Electric supplies the OSG 700-6251 countersink worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this OSG carbide countersink to any country.

How to select the right OSG countersink for your application?

Select the OSG countersink based on material, hole size, and desired chamfer angle. For standard flat-head screws, use an 82° angle. Carbide flutes suit hard metals; single-flute designs provide fast chip evacuation. Match the body diameter to your hole size and ensure proper RPM for clean cuts.
