• Speed may be adjusted to suit site conditions.<br />
• For very abrasive materials an increase<br />
28mm<br />
in drill speed (rpm) will prolong life.<br />
32mm<br />
• For harder materials, decrease the<br />
38mm<br />
drill speed to prevent overheating.<br />
42mm<br />
• Machine and material are the controlling<br />
48mm<br />
factors to the life and speed of the core.<br />
