20mm hole cutter for reactor lid
Hi All,
I thought I would save myself £28 on the upgraded Koralin Ca reactor lid that a certain well known Essex store sells.
The only difference between the standard and enhanced one is a cable gland is in placed additionally.
I've got the correct size gland for me PH probe (cost pence). All I need now is to drill a 20mm hole through the lid (which I think is made of some kind of nylon / plastic.
Anyone know who sells 20mm hole cutters cheap? I don't want to pay £15 for one. The actual cutters can be got for about £3, but then you need an Arbor (or whatever it is called) for it (£7 to £8) then add on postage and you are up in the £15 mark,
Love to hear if anyone knows anywhere around Sheffield that does em. I've searched online - (Screwfix etc) but its comming out around £15.
Am I being tight here??? :p Just figured if there is easy money to be saved, its worth it.
