One of the key functions of 13mm keyed check percussion drills is that they all feature a keyed chuck system, which means a chuck key is required to change drill bits.
Percussion drills are all mains powered and feature a hammer action which enables drilling into hard materials such as brick and concrete. Other materials such as wood, metal and plastic can also be drilled using percussion drills.
The maximum drill bit size that these drills can accommodate is 13mm, which makes them suitable for larger jobs. It should be noted that these drills do not support SDS tools.
- The key consideration when choosing a percussion drill is the maximum drilling diameter required. 13mm refers to maximum drilling diameter in concrete & brick. You can use a larger drill bit for metal, plastic & wood (& some machines allow this in concrete & brick too) providing it has a 13mm or smaller diameter shank to fit the chuck. The drill bit is tightened into the chuck using a key supplied.
- There is often a choice between single or 2 speed gears. Most percussion drills have a variable speed function.
