• When used with the DTASCGW, the drill bit will be kept centred and a strait stream of water provided.
• If a guide is not available, start the drill bit on a 45 degree angle and once a shallow hole has been created, move the bit to 90 degree to drill as normal.
• Recommended use is 1000-1500RPM.
• Pushing too hard when drilling may damage the bit. After every cut, use a thin piece of metal to remove ant material that may have been caught in the bit.
• It may become difficult to effectively drill if the bit is not cleaned.
