With a screen name like yours unlikely in your case at least. Probably more Amul Butter like.😀lovejeetactually a girl's heart is the hardest thing known on the earth.........😛

For the obvious reason that diamond is harder than glass. So it scratches it. Actually diamond tipped tools are available to drill holes in glass. I have a much simpler method. You can easily drill glass (and concrete and ceramics) with just a hollow copper tool. File the tip into a rough saw tooth shape, make a paste of emery powder in water with some detergent and drill with the copper bit using this paste at the bit. The emery powder gets embedded in the soft copper. Being harder than glass, the powder bites into the glass. I have used it many times. Even now I use it to drill drain holes in ceramic pots for bonsai use.rkvasan68And for what reason they have been used for cutting of glasses.
any know the reason..?

Mohs Scale is the commonly used measure of mineral Hardness. This lists 10 common minerals based on which scratches what. Modern usage has added other common items to the list to get intermediate hardness values. Most drill bits fall below glass. Traditionally, diamond impregnated bits are used to drill glass and other ceramics.silverscorpion^^ Maybe a little off topic.. But, what do you mean when you say diamond is "harder" than glass?
Why can't we use normal metal bits to drill or cut glass? Because glass is brittle? Then how does diamond solve it?

The same thought crossed my mind SS, my guess is that the diamond tip wont get dullsilverscorpion^^ Maybe a little off topic.. But, what do you mean when you say diamond is "harder" than glass?

Yes you are right CE Designer, Diamond tips are harder and the tip can't get blunt easily so,CE DesignerThe same thought crossed my mind SS, my guess is that the diamond tip wont get dull

SiC is softer than diamond. Please see the Mohs Scale at the link in post 10 above.saptmsilicon carbide is the most hardest metal.Infact it is harder then diamond.
@saptm-HQ4553 • Feb 27, 2012
You r right sir, diamond has 10 mohs no , SiC has 9.5 mohs no. but there is more than one crystal form for SiC; cubic, hexagonal, etc. Some forms of SiC might be slightly harder than diamond.bioramaniSiC is softer than diamond. Please see the Mohs Scale at the link in post 10 above.

As far as I know diamond is harder than all forms of SiC. That there are materials harder than diamond is not questioned.saptmInfact wurtzite boron nitride is equally harder than that of diamond.

Diamond wheels are actually used to cut granite.zaveriwhen i was in school, i heard that the hardest mineral is granite.
@hagomuk-kEKijA • Mar 17, 2013
Well now there are two materials exist which are harder than diamondCE DesignerI know diamond is the hardest MINERAL known to man but is there any other material that is harder?
