Frequently Asked Questions

What is the OSG 701-3750 countersink used for?

The OSG 701-3750 is a 60° carbide countersink with 20 flutes, designed for deburring and chamfering holes in metalworking. It creates precise 60° countersinks for screw heads or chamfered edges, commonly used in machining, aerospace, and automotive applications where high finish quality is required.

What are the specifications of the OSG 701-3750 countersink?

The OSG 701-3750 is a multi-flute countersink with a 60° included angle, 20 flutes, and a 3/8 in body diameter. It is made of carbide for durability and wear resistance. The manufacturer part number is 701-3750, and it is designed for use with standard drill presses or CNC machines.

Where to buy the OSG 701-3750 countersink worldwide?

3G Electric supplies the OSG 701-3750 countersink worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your facility.

How to select the right OSG countersink for your application?

To select the right OSG countersink, match the included angle (e.g., 60° for standard screw heads) and body diameter to your hole size. For hard materials like stainless steel, choose carbide flutes for longer tool life. Ensure the shank fits your tool holder, and consider flute count for chip evacuation in production runs.
