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
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 !
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
A pillar drill is used for larger holes, more exact placing of holes, or drilling repeated holes with a jig to insure uniformity.
easiest way is to core drill and use pour stone to cement it.
You should use an impact driver instead of a drill when you need to drive long screws or bolts into tough materials like metal or hardwood, as the impact driver provides more torque and power for these tasks.
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.
shell type core can be used
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.
