Frequently Asked Questions

What is the OSG 701-2502 countersink used for?

The OSG 701-2502 is a 90° multi-flute countersink used for deburring and chamfering holes in metal, plastic, and composite materials. Its 18-flute carbide design provides smooth, chatter-free operation in CNC and manual machining applications, producing a clean 90° countersink for screw heads.

What are the specifications of the OSG 701-2502 countersink?

The OSG 701-2502 is a 90° countersink with 18 flutes and a 1/4 in body diameter. It is made of carbide and has a manufacturer part number 701-2502. This multi-flute countersink is designed for precision chamfering and deburring in industrial machining.

Where to buy the OSG 701-2502 countersink worldwide?

You can source the OSG 701-2502 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 multi-flute countersink.

How to select the right OSG countersink for your application?

Select the OSG countersink based on the required chamfer angle (90° for standard screw heads), material hardness (carbide for steel or abrasive materials), and flute count (18 flutes for smooth finish). Match the body diameter to your tool holder. For high-volume production, OSG carbide tools offer extended tool life.
