hole saws/cutter which type??

[timtheenchanter]

just getting round to buying a replacement to my diy set of hole saws, and wondered which to get as a sparky?

hole saw kits are widely used, but make a hell of a mess and ket carp in your eyes/hair if using them overhead.
ie this type

wondered if the hole cutters were any good, or a bit of a gimmick?

the one in the link is for boards and wood

do you need it for sheet metal or masonery???

 

[timtheenchanter]

its probably going to be for boards/wood (dare i say it, for down lights etc...)

not going to be boring holes through bricks just jet (not that size anyway)

The hole cuttery thing in your link is rubbish. If you'd have asked about five years ago you could have had mine before it went in the bin.

Buy some proper holesaws and they'll last you for ages.

The ones in your picture are rubbish as well.

I've found starrett, CK and bahco holesaws to be good brands.

Always drill on a low speed, especially on down lights. If you can get it so the drill is barely turning and you could probably turn the holesaw quicker by hand then you're about right.

This stops all the dust being flung everywhere and a well positioned box on top of your steps shold catch most of the just while you remain almost dust free.

Also use a low speed for cutting metal as it stops the saw getting too hot. I've had my 20mm holesaw for 3 or 4 years now and it gets used on steel most days.

i once used a cutter like the one in the link .set it to somthing like 70mm the problem is you cant really see the blade when cutting because of the guard. the upshot was the blade slipped and when id finished i could get my head through the hole .first and last time i used it .
