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?

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.
