Glass drill bits allow anyone to create perfect holes in glass, without cracking or shattering your workpiece. Here are our recommendations for the best ones.

We used the DeWalt bits to drill through travertine, slate, marble, ceramic, and glass tiles. The bits have carbide spiral tips, and we tested them with and without masking tape. The deep flutes ...

The Longyear Diamond Bit Color Series is an innovative and versatile new line of diamond coring bits. Utilizing patent-pending technology, these bits are engineered to drill faster, last longer ...

The more durable diamond bits don't have moving parts, but they can drill faster for longer in most shale rock. Now, smaller moving parts are being incorporated into the fixed bit.

Polycrystalline diamond drill bits open up options for geothermal energy Date: March 19, 2012 Source: DOE/Sandia National Laboratories Summary: Nearly two-thirds of the oil we use comes from wells ...

Nearly two-thirds of the oil we use comes from wells drilled using polycrystalline diamond compact (PDC) bits, originally developed nearly 30 years ago to lower the cost of geothermal drilling.

Drill bit manufacturers have substantially improved polycrystalline diamond (PCD) cutters and drag bit designs since their introduction in 1972.
