The Quality Countersink Bit Source

Countersink bits are used to top off a pre-drilled hole with conical recess that allows a flat countersunk screw to finish flush with the material surface. They are made from high speed steel and come in smooth and hex shanks.

Countersink bits also see use in other hole applications such as cleaning, enlarging, deburring and chamfering.

Not sure how countersink bits can benefit your next application? Feel free to address all inquiries about countersink bits with one of our representatives today for the best advice on All Things Fastening and more.
