Description

30mm 90 Degree HSS Co5 Single Flute Countersink
Single flute countersinks are ideal for countersinking and deburring in a wide range of materials including ferrous and non-ferrous metals.
The fluted countersink cutter 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 light to medium materials.
Resharpenable.
M35 Cobalt High Speed Steel 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.
