| Diamond drill bits are easy to use, however, there are many special techniques that are different from standard steel-bit drilling. Diamond drill bit usage can also vary depending upon the type and the specific manufacturer. |
Recommended Drill Speeds | DiamondSure – Bonded Bits | Recommended Drill Speed (rpm) | | Material Bit Size –> | 1/2″ | 1″ | 2″ | 3″ | 4″ | | Fiberglass | 1200 | 700 | 350 | 250 | 175 | | Glass, Ceramic & China | 800 | 500 | 250 | 160 | 125 | | Limestone & Marble Stone | 600 | 450 | 225 | 130 | 100 | | Ceramic Wall Tile | 600 | 450 | 225 | 130 | 100 | | Porcelain Wall Tile | 500 | 375 | 180 | 125 | 90 | | Porcelain Floor Tile | 500 | 375 | 180 | 125 | 90 | | Granite Stone | 400 | 300 | 150 | 100 | 75 | (Not for use on Concrete or for depths beyond about 1/2″) | SPEED KILLS: | Reduced drill speeds, low drill pressure, and increased use of water lubrication will extend drill bit life considerably. | |
| Because diamond drill bits are used to drill in extremely hard materials, it is very important to use proper drill pressure to keep from overheating the bit. Excessive pressure is merely converted to heat energy and can burn up a bit very quickly |
Recommended Drill Head Pressure | Material | Drill Head Pressure * | | Fiberglass | 10 to 15 lbs. | | Limestone & Marble Stone | 12 to 18 lbs. | | Glass, Ceramic & Porcelain China | 12 to 18 lbs. | | Ceramic/Porcelain Wall Tile | 15 to 20 lbs. | | Porcelain Floor Tile | 18 to 30 lbs. | | Granite Stone | 18 to 30 lbs. | |
WARNING: Drill press arm leverages 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
