Gday everyone for a little while now I've been cabbing some local material both at home and in the gem club I have to say it's been a great experience so far I've learnt alot already and I'm keen to learn more after receiving some chain's and bails and diamond tip drill bits from a relative I decided to make a couple first is petrified wood and second is rhyolite
Diamond tip spade bits for drilling glass and tiles is what i would recommend they look like a mini spear . I used to drill glass bottles back in the day and i once drilled basalt rock so they would eat through those softer stones like butter :Y:
Like these but make sure their a good brand like Irwin or similar, dummings warehouse has them or magicfart.
