Frequently Asked Questions

What is the OSG 701-5001 countersink used for?

The OSG 701-5001 is a carbide multi-flute countersink used to create a smooth, chamfered hole for flat-head screws in metalworking and machining applications. Its 82° angle and 24-flute design reduce chatter and provide a clean finish on ferrous and non-ferrous materials.

What are the specifications of the OSG 701-5001 countersink?

The OSG 701-5001 countersink has an 82° included angle, 24 flutes, a 1/2 in body diameter, and is made from carbide. The manufacturer part number is 701-5001. It is designed for precision chamfering in industrial machining operations.

Where to buy the OSG 701-5001 countersink worldwide?

3G Electric supplies the OSG 701-5001 countersink to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this carbide multi-flute countersink.

How to select the right OSG countersink for your application?

Select the OSG countersink based on the screw head angle (82° for flat-head screws), material (carbide for hard metals), and body diameter matching the hole size. The 24-flute design minimizes vibration. For specific advice, consult 3G Electric’s technical team.
