<p><b>Useful Information</b></p>
<p>Set to rotary mode only, never apply using the impact mode, as using impact mode will damage the drill bit and the tile. Use gear setting 1 with a cordless machine prevents the drill bit from overheating, if using a corded tool, in addition to setting it to gear 1, control the speed by pushing the trigger halfway only in order not to go over 500rpm. If you're using a cordless tool, you don't need to control the speed through the trigger once the tool is set to gear 1, due to cordless tools' lower rpm limit.</p>
<p>A scraping or screeching noise when the drill bit starts removing the material confirms the right amount of pressure is being applied, the drill bit is working correctly, please note cooling is not required. Adding a little bit of 'wobbling' motion when drilling through slightly harder tiles can help gain speed and extend the working life of the drill bit. Once a hole has been drilled through the tile, switch to a concrete drill bit to tackle the material under the tile (concrete or brick) making sure the power tool settings is reset to impact mode and gear 2 before starting to drill with a concrete drill bit.</p>
