Drill bits are made from different grades of raw steel which are delivered to manufacturing plants. The steel goes through a process of cutting and heat treatment at extremely high temperatures, to harden the steel. The bits are then cleaned, tempered, grounded, fluted and pointed. Specialist drill bits go through additional processes such as split pointing.

Both cobalt and titanium drill bits are used to make holes in hard, tough materials like metal. Cobalt drill bits are the toughest you can get, and have no coating, unlike titanium drill bits.

It is important to make sure that you use the correct type of drill bit to match the material you are drilling into. When choosing which drill bit to buy or use, consider its material, its strength and cutting power.
Drill bits are very good value for money. General purpose drill bits are the lowest price. For example, a pack of 10 HSS Roll Forged Drill Bits starts from £1.16 (inc VAT). Specialist drill bits such as multi-cut stepped bits can be more expensive. Generally, the longer and wider the drill bit, the more expensive it will be.
We sell a wide variety of drill bits, including individual and drill bit sets for wood, metal and plastic, masonry, HSS, cone/multi-step and more. Take a look at our extensive range.

These drill bits are not as robust as cobalt drill bits and you cannot sharpen them without the risk of removing some of the coating.
American Steven A. Morse, from Massachusetts, invented the twist drill bit in 1861. Before his invention, drilling was a slow and laborious process because drill bits were made from a pointed, sharp, flat piece of metal which overheated too quickly. He wanted to develop a more effective way to drill a hole and gained a US patent for a twist drill in 1863.
In terms of length, use a drill bit which is as long as the screw or object to be inserted. For example, a 40mm screw would need a drill bit that has a flute length of at least 40mm.
