hi all
drilling tapholes in an acrylic bath
i was thinking of using a diamond - tipped holesaw-the type used for porcelain tiles- for drilling my new acrylic bath (mere with carronite reinforcing). is this ok?
i am buying some of these cheap from a chinese site for the porcelin tiles going in too (the circular type without the pilot bit) will use a guide too, an adjustable plate and sucker job with 4 bearings to hold the bit steady. so i figured it would b handy if i could use them on the bath as i dont have a decent holesaw with auger, and they are expensive from what i have seen.
i read somewhare a carbide steel bit is best with the teeth ground down to a shallower angle, so u are effectively grinding the acrylic, fine if you are doing this all the time.
if its ok to use should i drill fast or slow, and use some water for cooling, lubrication?
any pointers greatly accepted
