About this item:

• 5 Pce 10-30mm 90 Degree HSS Co5 Single Flute Countersink Set
• 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.
