Countersink Drill Bits

If you are looking for a truly professional finish to your woodwork or metalwork, then the use of a countersink drill bit is a must.

Countersink drill bits create a recess in which the screw or bolt can sit, so that it is flush with, or even below, the surface level. These recesses can then be capped or filled to create a smooth and seamless surface finish.

Types of countersink drill bits

When it comes to drilling wood, these drill bits come in two main styles. Firstly there is the straightforward countersink drill bit for wood, which is used after the main pilot hole drill bit, in order to create the countersink.

Alternatively, you can accomplish both tasks at once by using a combined pilot hole and countersink drill bit. This will both drill the pilot hole and finish it off at the same time and ensures that the countersink is perfectly centred on the pilot hole.

Choosing your countersink drill bits

The most important factor in choosing countersink drill bits is the material you intend to drill. Wood drill bits are very different to metal ones and you must choose the correct type of bit for the job. As a rule, you will get what you pay for, and investing a little extra will usually mean your drill bits will last longer and perform better.

You also need to decide what size of countersink you are aiming for, which you can find by measuring the head of the screws or bolts you intend to use. Countersink drill bits come in a range of sizes, but if you do a lot of wood or metal work, it may be better value to buy a set of varying sizes.

Other uses of countersink drill bits

As well as creating countersink holes, these drill bits can also be used to finish off the edges of a drilled hole. This involves removing any rough edges or surplus material from the hole in order to make the finish smoother and safer.
