DIFFERENCES
|
(with
the bits for hand drill) The conical threaded point of the F.E.D. bit is has a narrower pass and removes less shavings allowing a faster spinning and a better adjustment to the speed of the drill. It also enables the removal of the bit before finishing the hole. |
|
|
|
|
RECOMMENDATIONS
|
||
 |
Use drills with reverse operation (the major bit heating occurs when it is removed in the same direction of advance). | |
|
|
Use the drill at an 90º angle. | |
|
|
Softly push the drill (it is enough for the tool to advance). | |
|
|
When working with hard woods (especially Hitin) it is advisable to remove the bit from the drill every 4-5 cm of perforation and submerge it in water mixed with oil (the water cools and the oil lubricates), then go on and repeat the same steps. | |
|
|
In order to maintain the polish, after each spell of work, clean the bit out of any remain of wood and lubricate it. | |
|
If the instructions are followed, we guarantee
excellent results
