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.
