Wood Drill Bits Explained
What drill bits are best for wood?
Selecting the best drill bits for wood will depend on the diameter of the hole you need to drill and how thick the material you are drilling is.

- Spade Wood Bits are great for most hole diameters up to 32mm
- Holesaws are great for larger diameters from 32mm up to over 100mm
How can you tell if a drill bit is for wood?
A standard wood drill bit will typically have sharper edges on the flute and always feature a sharp brand point at the end of the bit. This is to allow you to start the drill bit in the exact position you want to drill the hole without the risk of the drill bit skidding off. These drill bits are usually made from carbon steel, which is ideal for wood drilling, but not for drilling other materials.
How to tell if a drill bit is for metal or wood?
Typically, the product packaging will explain which materials can be drilled with the particular bit. If you no longer have the packaging, then a wood bit usually has a sharp point on the drilling end which helps the bit bite into the wood and not stray away from the drilling area. These bits are designed specifically for drilling wood so are not suited for drilling other materials.
Metal drill bits can either be black, silver, or brass/bronze, with a different point geometry on the end. They can still be used to drill wood but are best suited to drilling metal materials.

These bits are typically High Speed Steel (HSS) which is ideal for drilling metal but can also drill wood and plastic well. This type of drill bit isn't very common so can usually be purchased from specialist tool/hardware retailers.
