82 Degrees Countersinking Drill Bit Set 12/16/19mm 5 Flute for Wood working

Countersinks are mainly used for countersinking drill holes, countersinking screws and deburring. Countersinking widens the drill hole and facilitates subsequent tapping. When countersinking screws, space is created for the screw head so that it closes with the surface of the workpiece.

  • Check the chamfer angle of your screw heads. Most are 82°, but metric screws are often 90°, and other angles exist. If your countersink angle doesn’t match, the screw won’t sit properly. If the screws are hidden, much of the time it won’t matter, but if they’re visible, it looks wrong. In hardwoods, it can even weaken the screw head, and in extreme cases cause it to break.
  • Mark the position with a center punch first when drilling holes in metals. Solid models are tapped gently with a hammer; spring-loaded models are simply pressed until they activate.
  • Work out the required depth carefully when doing counterbores. Too shallow and the screw won’t grip properly. Too deep and there’s a danger of it pulling through.
  • Deburr holes, too. A countersink isn’t just for making recesses. One is also the fastest way to deburr a hole in sheet metal or pipework. A quick twist by hand is often all that’s needed.
