We are Spade Drill Bit Factory. Let me introduce the diameter specifications of drill bits.

  1. There are many specifications for drill bits. For example, the drill holes through which some water pipes pass are relatively larger, while the drill holes required for wires are much smaller, so the diameter of the drill bits is also different.

  2. The diameter specifications of the drill bits are roughly 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 9.8mm, etc., each 1mm apart, there is an accumulation of 0.1mm, such as drills with diameters from 1mm to 2mm The specifications are rounded by 0.1mm, and there are larger ones, which are generally not used for oil drilling. Except for oil exploration.
