Is there a drill bit made of the material of grinding wheel of orbital grinder, which breaks down slowly as it drills, or maybe it can be made of like diamond -studded metal file, so that the drill grinds as it drills, instead of cutting through the metal? Thank you for your interest.
The closest you can get to a general purpose drill bit is a basic twist drill made for metal. That works equally well on softer materials like wood and plastic. Other than that, no. You typically choose the bit based on what you’re drilling into. Also, not all twist drills are made equal. HSS-R (rolled) works for wood, plastic and soft metals like aluminium, copper or brass. HSS-G (ground) is the bit you probably should be using especially if you’re drilling into steel. Then there’s also HSS-Co or HSS-E (cobalt) which is for hard metals like stainless steel. Then there’s also carbide bits but those are for drill presses and such.
Diamond bits work the way you describe but they’re for ceramics and glass. If you try using one on wood or plastic it’ll just clog up immediately. There’s a reason twist drills look like that: they’re designed to lift the removed material from the hole so that the bit can drill. A bit similar to how an orbital sander works much better with a vacuum attached so the dust layer doesn’t sit between the sanding disc and the surface you’re sanding.
Then again, for concrete you not only need a masonry bit but ideally one with an SDS+ attachment for a dedicated hammer drill. You could technically use a diamond or non-hammer masonry bit as well but it would be extremely slow and you’d probably overheat the bit which affects the heat treatment of it which then causes it to get dull and quit drilling and just start heating up even more.
maybe the grinding drill bit can be shaped into a spiral, so that as it grinds, the left-behind material gets pushed out of the drill hole.
So you want a normal spiral drill. It does exactly that, it just cuts small flakes away as opposed to grinding them, but the difference is moot and the results the same.
think of the person you stole from, and ask for forgiveness in the mind, even if you stole something at nine years old. This will clear your head of running thoughts, clear your mind of mental fog, and help you sleep better at night, so you can make better decision, judgments, and life choices. Otherwise, you will just delete others and yourself using Alzheimer’s disease. Use “there is a right way to do anything”, to keep yourself in the clear-minded state. Do this, even if you stole something at nine years old, stole something one time, stolen a small piece of Lego toy, or stolen from a family member or relative (in which case, you might need to personally apologize to the relative).
Is that why you need to grind rather than cut? Not sure what this has to do with drills.
