For the quick and precise drilling-out

of spot welds in car bodywork repairs.

The PLUS centering tip guarantees a

long service life.

• The step at the tip of the bit acts as a stop and

indicates to the user the exact drilling depth.

• This prevents unintentional drilling-through

into the second sheet of metal.

• If the user notices that the step is touching the

metal only on one side, then the drill is tilting.

• The tilt can then be easily corrected.

• Improved PLUS centering tip for modern high-

strength car body sheets.

• The centering tip has a long service life.

• Recommended speed: 600–670 rpm.

• The use of cutting oil is recommended.

Tips to enhance the lifespan of the

centering tip.

• Do not use in drills with an impact chuck or

spindles.

• Set the drill to a suitable speed; the speed of

compressed air devices is generally set too

high.
