Sore wrist

[Phil]

I was coring a 127mm hole in damp stone today and the bit jammed but did not engage the clutch and ripped the drill out of my hand, like an idiot I put it down to a one off and went again but the same thing happened. Its never jammed before in 4 years.

I'd drilled the 117mm inside and the clutch was kicking in all over the place but when I went outside to the stone I put in the bigger 127mm core and it didn't engage the clutch when it jammed in the damp stone dust.

I rarely use the bigger bit, I think maybe my drill isn't powerful enough?

I used to use a cheap Titan drill for core cutting till it through me round the room when it jammed.

they all jam thats why core machines have the clutch which drill was it

Same here. I was up a double ladder at the time, coring from outside on a 1st floor installation. I still to this day do not know how I managed to stay on the ladder but I ordered a Marcrist the same evening. Gave the Titan to the trainee...

think I mentioned using sds and cores in an earlier post.............. 🙂 presume it was sds as it jammed so well 🙂

Lol you're a bad man Mas

 

[Phil]

No...This was a proper core drill that jammed.

 

[lame plumber]

if a marcrist jams at 3500 you'd wizz round with it 🙂 Dont worry Phil, your sex life will return once the wrist improves 🙂

My last core drill started jamming after loads of abuse, everything has a finite life 🙁

Just fabricate a 24 inch side handle lol

its happened a couple of times to me, once coring a flue stood on the second top rung of steps, that hurt, another time i was putting a 25mm bit through a wall by the side of a toilet pan for the overflow, drill jammed, spun out of my hands and smashed the back of the pan, water everywhere and a new pan at my expense.

It was .....er....the...erm....Sparky one. ...(cough).. :disappointed:

If it jams again on Sunday when I drill a dryer vent and the clutch doesn't engage then Its on mixing drill duties and I'll have to get a ddm1 or Makita or maybe the Metabo one.

So I drilled this hole this afternoon and when it jammed the clutch kind of engaged but restored drive half way through and ripped itself out of my hand again, I was holding the side handle really hard. also the hexagon shaft keeps coming out of the chuck no matter how hard I tighten it and the motor has started smoking when pushed and big sparks can been seen in the motor housing when used.

I think its too dangerous to use now.

small sparky lasts me about a year, the sparky ddm2 model is similar to the marchrist one no longer made, lovely beast, shame I cant hold it now
