What size drill bit do I Need?
When you are drilling into softwoods, always choose a bit 1/64-inch smaller than the target hole size. However, when you are drilling into other materials, choose a bit that is exactly the same size as the hole. In case you are not sure which one to choose, use a drill bit that is 1/64-inch larger than the hole you want to drill.

What does 2.5 mm cable mean?
2.5mm cable means a cross sectional area of 2.5mm of the live or neutral wire. This cross sectional area. or in more simple terms the area of the exposed face of the wire, does not include the insulation around it. It is purely the area of the copper wire.
What is 2.5 mm cable?
2.5mm Twin and Earth is commonly used as indoor domestic cable. The most common use for this type of cable is for circuits that provide power to sockets. It is made up of two cores and an earth core which must be covered with the identifying green and yellow sleeve when installed.
What will 2.5 mm cable take?
how many watts can a 2.5 mm cable take? 2.5 square BV wire, overhead wiring at 20 degrees, 220 volt power supply can be up to 4.4KW. Therefore, a 2.5 square BV wire can be used with a maximum of 4.4 KW.
What is 2.5 mm electrical cable used for?
2.5mm is commonly used for behind sockets, while 1-1.5mm is most often used for lights (depending on how many lights you have in a circuit).
What is the measurement of drill bits?
Drill bits are available in different materials, lengths, and diameters. Most are measured by the metric units and in the USA it’s imperial units. Drill bit diameter is the most important factor in the drilling process and it should know precisely as much as possible to sharpen or tolerate the diameter.
How many mm is 1 inch?

How many inserts are needed for a drill bit?
Each drill bit requires two inserts— one on the inner cutting edge and one on the outer cutting edge. Bits can be used in CNC machines with coolant-through technology; holes in the bit allow coolant to be channeled through the tool for more efficient chip evacuation.
What is a tooth bore bit?
Multiple outlining teeth bore clean, flat-bottom holes without chipping or splintering your surface — even when cutting across the grain. These bits are excellent for boring straight holes, overlapping holes, and holes on close centers in soft wood, veneer, and laminates. The center guide point prevents the bit from wandering. Also known as multispur bits or Forstner bits.
How many splines are in a masonry shank?
They are hollow and cut with their outside edge for drilling large holes. The shank has 12 splines for use with a spline-drive rotary hammer. Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules. This type of bit drills faster and penetrates material with less pressure than rotary-only bits. Also called percussion or impact bits.
What are hollow bits?
These hollow bits cut with their outside edge for drilling large holes. Instead of using a hammering action to break up masonry material, these bits drill with rotary action only, requiring more pressure to grind up material. Use with handheld power drills, drill presses, and in hammer drills set to rotary-only mode. Do not use in hammering applications. To achieve maximum drilling depth, break up and remove the core every 4” before drilling deeper.
How to drill a hole in masonry?
Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules. This type of bit drills faster and penetrates material with less pressure than rotary-only bits. Also known as percussion or impact bits. To achieve maximum drilling depth, break up and remove the core every 4” before drilling deeper.
