  • 【High Speed Steel】Our woodworking countersink bits are made of high speed steel, and the black bevel is made of carbon steel, which has improved toughness and wear resistance.
  • 【Adjustable Depth Control】This countersink bit set features an adjustable depth stop ring for precise control of pilot hole depth to ensure consistent and accurate countersinking for a professional finish.
  • 【Efficient Drilling and Perfect Finish】The 82-degree countersink bevel angle enables smooth, fast drilling in hard and soft wood. The tapered pilot drill ensures fast, clean pilot holes and a tight fit for the screws.

Once the screw has been screwed in, the screw cap lies below the surface of the PCB.
