Hence you should know both thicknesses in order to determine the hole diameter. Normally, wires have conductive cable and insulation thickness. Always drilled holes should be equal to or larger than the wire size. When you drill for screws, this guide will help you to find the drill bit sizes for screws.ĭrill bit size is very important for wirings. You can use below drill bits when you drill a hole for 3 conductor wires. 3 conductor wires have different size gauges. Wire Gaugeĭrill bit sizes for 2 conductor wires Drill Bit Size for 3 Conductor Wiresģ conductor wires and 3 core cables are the same in name and have 3 conductive cables inside the single wire. It helps to find any drill bit related to the mm or inches easily. To avoid break-outs and chipping, you can stick to bigger round-shank types. If you need drill bit sizes that are larger than 1, you can often use a spade bit for wood and other soft materials. I have prepared a guide to find drill bit sizes in inches and mm. And sizes for step drill bits: Range from 1/8 to 1-3/8. When you drill a hole for 2 conductor wires you can select drill bit sizes from below table. Drill Size (mm) Closest American Drill Drill Size (mm) Closest American Drill. Wire gaugeĭrill Bit Sizes for Single Wires Drill Bit Size for 2 Conductor WiresĢ conductor wires, double wires, and 2 core cable wires are the same wires that have 2 wires in a single cable.īoth cables are coated with electrical insulations. Diameter 75 Thread for Aluminum, Brass & Plastics: 50 Thread for Steel, Stainless. So let’s see what are the suitable drill bit sizes for each wire size. When you choose a drill bit for a wire, it should be more or equal to the diameter of the wire (including insulation and conductor). Standard wire sizes and insulation thickness for Poly(Vinyl Chloride) Insulations Drill Bit Sizes For Single Conductor Wires As a result of this, the wire diameter will be increased due to this layer. Subtract the result from the thread diameter (4.0 mm) The result is 4.0 mm - 0.8444 mm 3.1666 mm, which is the necessary diameter for the drilled hole. Match this row to the 65 thread percentage column. According to the voltage and current, the layer’s thickness varies. Look for the 1.00 mm pitch in the charts first column. These standard wires are insulated with Poly (Vinyl Chloride) in order to prevent the current leaking. The drill bit size should be equal or more than the wire size
