Product Description

OSG Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is the OSG 706-7500-090 countersink used for?

The OSG 706-7500-090 is a 90°, 6-flute carbide countersink used to create smooth, chamfered holes in metal and composite materials. It is ideal for deburring and countersinking screw holes in industrial manufacturing, aerospace, and automotive applications where a fine surface finish is required.

What are the specifications of the OSG 706-7500-090 countersink?

The OSG 706-7500-090 has a 90° included angle, 6 flutes, and a 3/4 in body diameter. It is made of carbide for durability and precision. The manufacturer part number is 706-7500-090, and it is part of OSG's Smooth-Finish Six-Flute Countersinks series.

Where to buy the OSG 706-7500-090 countersink worldwide?

You can source the OSG 706-7500-090 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 OSG tool.

How to select the right OSG countersink for your application?

To select the right OSG countersink, match the angle (e.g., 90°) to your screw head type, and choose body diameter (e.g., 3/4 in) to fit the hole size. Carbide flutes like the 6-flute design provide smoother finishes on harder materials. Always verify the manufacturer part number, such as 706-7500-090, for compatibility.
