There are a staggering number of different types and sizes of drill bits available.... 3 to 10mm bits are ideal for everyday drilling through wood, metal and plastics.
4, 5, 6, and 8mm are ideal for masonry and concrete... you can buy other sizes as and when the need arises.
Few safety tips: (assuming you are handling the machine for first time)
* Drill pilot hole...
* Select the correct drill bit for your work...
* Control the drill speed to suit the task at hand...
* Apply Proper Pressure to the Drill...
* Do not force a jammed bit through... If the drill bit gets stuck in the material, you are using a wrong bit... don't try to force it out by running the drill. Unplug the drill, separate the bit from the chuck, and remove the bit using manual tools...
* Unplug the machine while changing bits...
* Do not under estimate the reverse torque the machine can create.
Happy drilling.
