Some Pointers and Tips on Drilling: USE A SHARP DRILL BIT AT ALL TIMES. Generally, a Drill Bit can be used for approximately four (4) hours of use before it needs to be sharpened. Apply light pressure when sharpening. Too much pressure may cause flaring of the tip which renders the Bit unusable. Drill Sharpeners are available and are recommended with purchase along with an extra drill bit. Sharpening stones are also recommended to debur the outside cutting edge of the drill bits for better performance. Use of Drill-Ease or Spin-Eze lubricant is required. Finally, purchase drill blocks to stop the drill bit after it penetrates the drilled material. |
