HFD Drill Bits 2.0 mm O.D x 150 mm long.
Drill speed should be high . Only use short increments removing regularly to clean the flutes of the drill to prevent friction and heating of the drill bit which will cause the drill to become fluid and take the path of least resistance between fibres rather than through.
NOTE: If using a Dremel drill you will need to use the optional drill chuck accessory. This is necessary to accommodate the 1.9 and 2.0 mm drill bits which exceed the maximum collet size of the Dremel.
Use the guide rods provided in the installation kit, to check the alignment of the drilled holes before inserting sleeves. If the alignment is not parallel a new installation will be required.
