Frequently Asked Questions

What is the OSG 82° countersink used for?

The OSG 82° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its six-flute carbide design delivers a smooth finish and reduces chatter, making it suitable for precision deburring and countersinking in industrial manufacturing.

What are the specifications of the OSG 82° countersink?

The OSG 82° countersink has a 3/4 in body diameter, 6 flutes, and a 82° included angle. It is made of carbide for durability and high-speed cutting. The manufacturer part number is 706-7500-082, and it is part of OSG's Smooth-Finish Six-Flute Countersinks line.

Where to buy the OSG 82° countersink worldwide?

You can source the OSG 82° 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 on this carbide countersink.

How to select the right OSG countersink for my application?

Select the OSG countersink based on screw head angle (82° for flat-head screws), body diameter matching the screw head size, and material. Carbide flutes suit harder materials like steel or stainless steel. For softer metals, consider high-speed steel. Always match flute count to desired finish quality.
