That would depend on what you were drilling and what the project is.
It is a normal, straight drill bit, as opposed to the type with a tapered shank for use in industrial drill presses.
It depends on the material and the tool you use in drilling. If you use a bench drill to drill using diamond core bit, you must have a protected gears in machining and then stand straight beside the drilling machine. Use clamp to stable the material in the bench. If you use a hand drill, you must firmly hold and push the hand drill in toward the material downward. some of the tools of diamond core bit: http://www.gilatools.com/diamond-core-bits.html
Usually you use a core drill and remove a sample to whatever depth you require.r
typically referred to as a core-drill, it anchors to a surface and drills out large diameter holes......... actual drill bits for small holes (the type you'd use in your 3/8 drill or cordless) are carbide bits, and can also drill throgh ceramic tiles
You could buy a normal drill stand but i feel you will overload the drill and burn out the drill;these use a lever harder to judge the pressure your putting on the drill better with corded drill.ANS 2 -There is absolutely no point in doing this as nowadays small bench top drill presses are cheaper than good cordless drills !
easiest way is to core drill and use pour stone to cement it.
A pillar drill is used for larger holes, more exact placing of holes, or drilling repeated holes with a jig to insure uniformity.
shell type core can be used
Yes, you can drill polypropylene. Use a regular drill bit and keep speed about mid range. Too fast melts it instead of drilling and too slow may catch the edges of the bit.
Very slowly with a Carbide drill bit or Diamond core bit, both will work, but the diamond core bit works much better, make sure the bit has a constant flow of coolant or be submerged in the coolant. (go very slowly, do not apply much pressure, let the bit do the cutting) The best way is to use a drill press but a hand drill will work.
No
A 40mm masonite drill bit could work using the right drill. But consider using a coring machine instead because its concrete.
