Spotlights

[Jamiemfc]

Good evening

Looking for a few tips on the best way to open out cut outs for spotlights that are already there, got a job on tomorrow and the customers already bought the lights but the fittings theyve bought need a 10mm bigger cut out than the existing spot lights! Any tips greatly appreciated(im sure therell be little gadget out there someone knows of)and before anyone asks yes im a qualified spark just used to a more industrial setting(steelworks)!

Thanks

Jamie

i have used the holesaw on one side method about a dozen times usually to straighted up holes cut by blind men with blunt padsaw, however i am quite excited at the holesaw inside a holesaw idea a true example of the term engineer!

To use the two-holesaws method, you need one of these to replace the 'drill bit' arbor. Nice and neat, and works a treat. Loads neater than the padsaw method.

Starrett - A19 'Oops' Arbor - Saw Blades & Precision Tools

Awesome ! never knew this existed. I have tried this method before but with the inner cutter rattling around like billy-O.

Ah they are invaluable! They take small and large inside saws too. So simple, yet effective. Bit pricy at £13 but still worth it, IMO.

Denmans now do an attachment to add onto one of these. The attachment grips onto existing hole so cutter doesnt slip.
