Choosing a combined drill countersink
Match the gauge or screw size to the pilot drill and countersink, and pick HSS or TCT to suit the material. The replacement drill is listed so you don't need to buy the whole bit when the pilot wears. Always check the data sheet for the size range, countersink angle and material suitability of the exact bit before you order.

Combined Drill Countersink FAQs
What is a combined drill and countersink?
It is a single bit that drills the pilot hole and cuts the countersink at the same time, so a screw head can sit flush without changing tools.
Should I choose HSS or TCT?
Both are in the range. TCT (tungsten carbide tipped) listings are the option for harder or more abrasive materials, and HSS suits general work. Check the listing for the material it is intended for.
Can I replace just the drill?
For the P&N Quickbit TCT bit, yes. A replacement drill is listed separately so you only replace the part that has worn.
