Choosing a countersink
Pick the style for the job. Three flute bits generally give a smoother finish, single flute bits are listed for general use and cross hole bits are a deburring style. Choose the included angle (most listings are 90°, with 60° options from Bordo) to match the screw head, and the material to suit the work: HSS for general use, cobalt or HSS-Co5 for tougher materials, and solid carbide for hard or abrasive work. If you also need to drill the pilot hole in the same pass, see the combined drill countersinks. Always check the data sheet for the size range, angle and shank of the exact bit before you order.

Countersink Bit FAQs
What is the difference between three flute, single flute and cross hole countersinks?
All three cut a conical recess. Three flute bits have three cutting edges, single flute bits have one and cross hole bits have a cross-drilled hole that forms the cutting edge. Cross hole bits are often used for deburring, so check the listing for the intended use.
What angle countersink do I need?
Most listings are 90 degrees, which suits the common metric countersunk screw. Bordo also lists 60 degree cross hole bits. Match the angle to the screw head you are using.
Do you sell countersink sets?
Yes. Sets from Sutton, Bordo, Saber, Noga and Wiha are listed, including 3, 4 and 5 piece sets, and Noga offers solid carbide and HSSE-Cobalt sets.
