    i guess i'm not alone...over 90% do the same.

    i guess by concensus it's not very dangerous/risky behavior.

    If your only tool is a hammer, you tend to treat all problems as if they were nails.

      I unplug it when chucking something like a hole saw or fly-cutter just because they look scary and that makes me think to do it. Otherwise, no.

        Add me to the list of those who don't unplug when changing bits.

        I do unplug when changing belts. Saw a guy lose a finger between a belt and pulley once. Don't want to see it twice!

          I assume you didn't mean that the way it sounded

          I do know a guy who lost most of his hand in a drill press accident.

            Oh my. Just as I think it is safe to leave the press plugged in this bombshell appears. How did he lose his hand?

              Your hand is above the cutting surface normally, and below the switch. My father has a little (built in) benchtop, and due to its setup, the drillpress is on a switched outlet. Not physically unplugged but one would have to turn it and the outlet on.

              One could just as easily use a link belt and disconnect a link, as unplug it. Then turning it on, wouldn't matter.

                I saw a guy get his hand caught in a DP with a wood bit installed. It was a step bit for boring 1/2" holes and a screw pilot for plugs later.
                I had just warned him less than 30 minutes before to take off his gloves.
                It twisted his fingers backward around the bit and broke them in several places as well as cuts and wrist injuries.


                I don't unplug them though. I have my DP's set with the belt rather loose. If it hits any type of bind it will just slip on the pulley.

                This also help bits last longer as the bits are doing all the work and not being forced to cut by the motor.
                Nothing gets slung around on my presses. It may wear the belts a bit more, but I think its a good safe trade off.

                  Why unplug a drill press? The chuck key would only break 3 or 4 fingers.
                  My drill/mill has the same stupid switch as the bt3 and I would not trust it as far as it throws a piece of wood.

                    When I started to read this thread I thought I would keep my drill press plugged in when changing bits which I already was doing. Now I think I will unlpug it.

                      Most serious drill press accidents happen when drilling metal items.
                      When the bit starts to break through the backside it frequently grabs the piece as the fingers of what was the bottom of the hole grab the flutes in the bit.

                      If the piece is not well clamped to the table or long enough to be braced against the center column then the piece will swing around with 1/2 HP motor behind it. If it has sharp edges it will slice you to **** if you are holding on to the piece by hand and in its way.

                      Fortunately wood does not behave this way although it tends to make you lazy when drilling metal.

                      The other dangerous thing about DPs is getting your hand caught in the pulleys. That might cut a hand off.

                      So when drilling metal items, ALWAYS clamp it to the table and if long enough, brace the piece against the column so it won't spin when the bit breaks through. BE SAFE!

                        Yes, I always unplug it. I have forced myself into the habit of always unplugging everything when I change a bit, blade, etc.

                        Of course, I never leave anything plugged in, ever, when I am not physically at the machine and using it. Yes, I am a bit anal with it, but it's a good thing.

                        I have little kids, and I don't want any accidents. They are not the kind to mess with things that they know not to, but all it takes is once, and the neighbor kids are over a lot.

                          Like CWSmith I unplug to move the belts for speed changes, but not for bit changes. With both hands involved in the bit change, and the switch is so far from the chuck, it's never struck me as necessary.

                            He was using a large (1/2", IIRC) twist bit. The motor started unexpectedly, due to a fault in the switch, and the bit started to drill into his hand. The skin, tendons, etc. wrapped around the bit and it basically just unravelled the tissue in his hand, broke the bones etc. Took all of maybe 20 seconds - just long enough for us to hear the scream and hit the emergency stop.

                            The flesh was just shredded, not much the doctors could do to save it. He lost all four fingers and most of the thumb. He was left with a stubby thumb and about half of his palm.

                              No matter who says what, switches fail. I had a switch on my floor DP fail today, but in a good way. It fell down and turned off. The spring inside has apparently broken. Switches fail and to be safe, the best way to do things is to disconnect at the power source.
                              Though I don't do that now, I will be able to when my new shop is completed this fall with a little luck. I plan on having all receptacles at the 48" height above benches. Okay in an actual dedicated shop I think.

                                That sounds terrible. Just to much damage must have been a mess.
