Electroplate Bonded Diamond Core Drill Bits

DiamondSure brand Diamond Core Drill Bits, also know as Diamond Hole Saws, are used on glass, stained glass, ceramics, ceramic tile, porcelain, porcelain tile, slate, limestone, marble, granite, stone, and fiberglass.  All you need is water for lubrication.

Old fashioned Spear Point carbide bits no longer work
on the new type of super-hard floor, counter and wall tiles.

Diamond Drill Bits are the solution.

Core drill bits have a hollow center and cut a circle in the material to create a hole. This results in a hole the size of the drill and a smaller "plug" or "core" which comes from the center.  Diamond core drill bits are available in sizes from 5/64" to 5-1/2" (outside diameter).  The metric manufactured size of each bit is also shown below (mm), along with the exact inch measurement.

Diamond drill bits are easy to use, however, there are many techniques which are different from standard steel-bit drilling.  Be sure to review our detailed Drilling Tips & Techniques section. <Click Here>

(Not for use on Concrete or for depths beyond about 1/2")

IMPORTANT
Diamond drill bits require the use of proper lubrication, correct
drill speed and proper pressure.  Drilling methods and techniques
vary significantly depending upon the material being drilled.
Not for use on Concrete or with Hammer-Impact Drills
or for depths beyond about 1/2"

Please See: Drilling Tips & Techniques <Click Here>

* WARNING:  Drill press arms leverage hand pressure by a factor of about
6 to 8.  So 2 lbs. of hand pressure on the drill press arm will apply about 14 lbs of pressure to the drill head.

Glastar Diamond Drill Bit

Solid Tip Diamond Drill Bits
Electroplate Bonded Blunt Nose Diamond Drills
For glass, stained glass, china plates, & fiberglass!

Blunt Nose Diamond Drill Bits work with any drill - just add water for lubrication.  Glastar brand Diamond Drill Bits are much easier and safer to use than old-fashioned spear point steel drills and don't chip the work material.  Blunt Nose Diamond Drill Bits are used primarily on glass, stained glass, china plates or fiberglass.  Glastar Blunt Nose Drill Bits are designed to be used at high speeds up to 10,000 rpm.

Since Blunt Nose bits have a solid rounded tip, they are slightly easier to start when drilling on a curved surface, such as a bottle, when compared to using a Core drill bit, above.  However, since Blunt Nose bits drill out the complete hole, they also drill more slowly than the Core bits and they are generally not used on the super hard abrasive materials such as ceramic or porcelain tile, floor tile, limestone, slate, marble, granite or other stones.  Blunt nose bits are available in three sizes, 1/8", 1/4" and 3/8".  Core drill bits from 1/8" to 4" are also available - see section, above.  See also How to Use Diamond Drill Bits.
