Helpful information - tips and recommendations

Directions for stone & ceramic tile drilling
  1. Drill must be kept cool at all times with a water swivel. Failure to keep drill cool will result in loss of diamond tip. No warranty claims will be accepted if drill is not used with a water swivel.
  2. These drills perform to their optimum when used in a drill press. If work is to be carried freehand it is essential that the drill is kept straight to avoid tip breaking from the shaft. No warranty claims will be accepted when drills are used free hand.
  3. To start drill it is best to use a plywood or similar template to prevent the drill from moving across the smooth surface.
  4. Cuttings must be constantly cleared to avoid jamming the core inside the drill bit which will result in loss of diamond tip.
  5. Refer to table below for operating speeds:

Segment loss > back to selection
  usually caused by blade twisting or jamming in cut, overheating (coolant requirement 10-50 lt./min depending on machine and blade size), out of round blade, incorrect blade tension, blade too hard for material being cut, incorrect rpm, defective flanges, excessive cutting speed. Undercutting of steel centre also results in segment loss and is usually caused by inadequate quantity or direction of water supply, cutting too deep (road base or bedding sand) or blade shaft and machine axle not parallel.
Uneven segment wear > back to selection
  Check bearings and spindle for wear, machine alignment and equal water supply to both sides of blade.
Blade worn out of round > back to selection
  usually caused by incorrect mounting of blade, worn spindle, bearings or blade arbour. Can also result from blade being too hard for material ban cut.
Abnormal wear > back to selection
  usually caused by dirty water, insufficient water supply to blade, low powered drive motor, worn bearings or shaft, incorrect blade for material being cut.
Warped blades > back to selection
  Usually caused by overheating, incorrect mounting, unequal flange pressure, excessive cutting pressure, full depth cutting, high feed rate.
Steel centre cracks > back to selection
  Usually caused by excessive cutting pressures, incorrect blade tension, jamming or twisting in cut, overheating, blade too hard for material being cut.
Blade wobbles > back to selection
  usually caused by incorrect mounting of blade, worn bearings or bent shaft, blade rpm too high or incorrect tension.
Blade arbour out of round > back to selection
  usually caused by blade incorrectly seated, worn flanges, flanges not properly tightened or blade shaft worn.
Cut deviation > back to selection
  Usually Caused by cutting with blade of incorrect tension, excessive feed rate, worn bearings.
Slow cutting > back to selection
  Usually caused by blade becoming glazed due to use on material too hard for bond, excessive cutting pressure, high shaft rpm, slow full depth cutting, low machine HP, drive belts loose. To sharpen blade, make fast (3-4m/min) shallow (3-10mm deep) passed in the material being cut, or in sandstone or asphalt for quicker results.
