 |
A pin chuck is used to hold drill bits that are too small for a regular drill chuck to hold. | |||
 |
Regular drill chucks usually hold bits between 10 and 13mm (0.39 – 0.5 inches), whereas pin chucks hold bits between 0 – 2.5mm (0 – 0.09 inches). | |||
|
As well as drilling very small holes, small drill bits are often used for applications such as watch repairs and jewellery work. | |||
