Product Description

OSG Multi-Flute Countersinks.

Frequently Asked Questions

What is an OSG 90° countersink used for?

This OSG carbide countersink creates a 90° chamfer on drilled holes for deburring and screw seating. It is used in machining, metalworking, and fabrication across industries like automotive and aerospace, where precision edge finishing is required.

What are the specifications of the OSG 701-3752 countersink?

The OSG 701-3752 is a 90° multi-flute countersink with a 3/8 in body diameter, 20 flutes, and carbide construction. It is designed for high-speed, smooth cutting on ferrous and non-ferrous materials, with OSG's precision geometry for consistent chamfer depth.

Where to buy OSG countersinks worldwide?

3G Electric supplies OSG countersinks like the 701-3752 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this carbide 90° multi-flute tool.

How to select the right OSG countersink for your application?

Match the countersink angle (90° for standard screw heads) and body diameter to your hole size. For hard materials, choose carbide like this OSG 701-3752. Ensure flute count suits your finish requirements—20 flutes provide smooth, chatter-free operation on production runs.
