Sparks when drill stops?
I just got a 15.6 V craftsman drill with a brake. When I release the
trigger, I am noticing sparks through the vents in the back. Is this normal?--thanks. |

read the instructions. my new ridgid 18v has a brake that engages when the
trigger is released. the book says that sparks are caused by the brake engageing. "Toller" wrote in message ... "TheKeith" wrote in message ... I just got a 15.6 V craftsman drill with a brake.

Perfectly normal. Most tools are designed so that the sparks cannot be seen
through the vents. But some aren't. "TheKeith" wrote in message ... I just got a 15.6 V craftsman drill with a brake. When I release the trigger, I am noticing sparks through the vents in the back. Is this normal?--thanks. |

Thanks everyone for your help. Since the drill is brand new, taking it apart
to check the condition of the brushes is out of the question, I'm afraid, but I'm sure after reading some of your replies, that what's happening is normal. Thanks again. |

That is perfectly normal if your drill has electric brake. -- © Jon Down ® http://www.stores.ebay.com/jdpowertoolcanada |

Normal. The "brakes" actually a set of contacts in the switch that short
circuit the motor, and this is why it sparks. It is an old "slot car racing technique". When you turn off the motor, it still spins for a while and becomes a generator. If you short circuit the motor when you turn the power off, it will lock the armature, therefore, brakes the motor. "TheKeith" wrote in message ... I just got a 15.6 V craftsman drill with a brake.
