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?

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

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.
