Diamond Drill Bits for Glass, Tile and Stone Electroplate Bonded Diamond Core Drills

DiamoneSure brand Diamond Core Drill Bits, also know as Diamond Hole Saws, are used on all types of glass, ceramics, ceramic tile, porcelain, porcelain tile, limestone, slate, marble, granite, stone, and fiberglass. Just use proper speed, low pressure and add 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 4" (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. Please review our detailed Drilling Tips & Techniques section. <Click Here>

SPEED KILLS: Reduced drill speeds, low drill pressure and increased use of water lubrication will extend drill bit life considerably.

Recommended Drill Head Pressure

DiamondSure Diamond Drill Bits

Recommended Drill

Material
Head Pressure (lbs.) *

Fiberglass
5 to 8 lbs.

Limestone & Marble Stone
10 to 12 lbs.

Glass, Ceramic & Porcelain China
5 to 10 lbs.

Ceramic/Porcelain Wall Tile
10 to 20 lbs.

Stone Style Porcelain Floor Tile
18 to 30 lbs.

Granite Stone
18 to 30 lbs.

* 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.

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"
