Description
About this item:
- 20.5mm 90 Degree HSS Co5 Triple Flute Countersink
- Triple flute countersinks are ideal 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.
- 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.
