Tools & Gear Drills Countersinks
TRIPLE FLUTE COUNTERSINKS For countersinking and deburring in a wide range of materials including ferrous and non-ferrous metals. The three fluted countersink is self centering with wide flutes and is used to provide a heavy chamfer in the entrance to a drilled hole. This may be required to allow the correct seating for a countersunk head screw or to provide the lead in for a second machining operation such as tapping. Use on medium to hard materials. Resharpenable. All Bordo Countersinks are made from 100% M35 Cobalt High Speed Steel. Cobalt offers increased wear and heat resistance in alloy steels - stainless steels and other abrasive or difficult materials. This increases tool life in all production applications.
