Diamond glass core drill bits


Size: L75*3-150


Material: high quality metal bond, imported diamond sand                                                                             




Plastic tank                                       

Glass deep processing


Anhua Glass Drill bits have a certain-balanced relative-softer matrix (diamond and metal bond). During drilling in high rotation speed, the bit gets too hot, and then the metal bond can release the diamonds that it wears away and exposes the diamonds. The diamonds are the main cutting agents.


It the metal bond is too hard, the diamonds get plucked out and the matrix becomes a shiny metal surface, of cause, it doesn't cut anything.

But if it's too soft, the bit wears too fast----it sounds awesome costly process on your time and money.


With quality material and Italian Technic, Anhua metal bond is relative softer and in certain balance condition. It wears away to an extent to expose the cutting edges of the diamond.

Adopted Italian diamond-fill-in skill, the matrix is from level to level and tier upon tier. As you cut, the bit is worn back into new cutting layer surface.

Therefore, you can very efficiently consume the full diamond edge of Anhua Drill Bits.

New technic make drilling fantastic without chipping in quick penetration. Long lifetime is assured.

Thought it is really cool that every embedded diamond has its tail and uniformly distributed over the whole surface, like meteors shot across the sky.⇓ ⇓ ⇓ ⇓ ⇓ ⇓
