User Tips * Maintain constant drilling angle to avoid tooth damage. 

* Avoid restarting the same hole cut with pressure on the drill bit particularly if the drilling angle has changed – this can damage the teeth. 

* Use a drilling lubricant particularly when drilling thicker metals. 

* Use ‘slower’ speeds and maintain a constant drill pressure – this will enable maximum drilling performance and increase the drill bit life span.
