In engineering you can use items around the workshop such as posters on info boards or their may already be drill and hole sizes for tap for example a 6.8mm drill bit for a M8 tap on a technical drawing or bend tolerences for the materials thickness.
Use a carbide bit in a drill. Then install plastic anchors where the screws go.
they use it to get the right size of fabric to use
Actually, any protractor you can find online is life size, but here's a website you can use. Check the link for a website you can use.
Use 7/64 as tap drill and 9/64 as clearance drill
Your meaning is not clear. - If you are going to tap the threads in, use a 7/32 drill bit. If you want a hole that this bolt will slip through, use a 9/32 drill bit.
drill off the head remove whatever it held down use vicegrips to remove the rest becarful not to drill to deep or brake the saft off or youll have to drill and tap out the hole for another size screw
I use a 3/8 bit for tapping fine thread, or a 11/32 for coarse threads.
4.3 is best or a 4.2 but use pleny of oil
You drill the bolt out that is snapped off in the engine,with drill bit made to drill through metal. Then use a thread maker,tap. Auto parts stores carry these. I no u can get at autozone. The tap makes new threads.
If no drill bit this size available, can use EDM service if metal is used
Not unless it was reasonably loose. Usually when faced with this, I drill into the bolt with a very hard drill bit a tiny bit thinner than the bolt - ie if it's a 3/8 bolt, I drill in first with a 1/8 drill to create a guide hole, then after with a 5/16 drill to cut right through, yet not harm the threads. You have to be very careful to stick to an exactly straight course. After the hole is cleared, I pull the threads left from the bolt out as far as I can, then use a 'clearance' tap of bolt size to re-tap the hole.

I use a 3/16 drill bit for that.
I would use a 5/8 drill bit which is almost exactly 16mm.
