Core Drill bits

[ambert]

Hi All,
I'm quite new to the trade, so I didn't have a lot to spend on tools. I bought some cheap core bits, but I find every time I use them it's a real pain to get them off the arbour. The drilling winds it on so tight I can't get it off on site, needs a vice and long steel bar to loosen it. Just wondering if there are any tricks to stop it tightening too much, or is it just my cheapo bits.

hi ambert try squirting a bit of WD40 or likewise on the screw shaft before assembly, i'm sure you will find them easier to dismantle afterwards.

copper grease or something? maby wd40 will dry up because of the heat?? use 2 open end spanners to open them and try to aling them so that the 2 are close together (hard to explain on this) but if you were looking from a side view, you dont want the 2 spanners like clock fingers at 12:30 ( hard to put tension on) you want them more like 12:05 , anybody understand me? and can explain this easier?? haha

In other words if it is possible to put 2 spanners on whilst it is flat on the floor and they are in a 10&2 position you can get your body weight behind it thing burpe position and your good

Sit the gun on the ground.
Get your 2 spanners on the core and arbor.
Lift both spanners (and the drill) off the ground about 4" and bang the core on the ground.
It will slacken in no more than 2 attempts.

Easier and quicker to do than type.
