Magnicon Bond Diamond Core Drills
(Metal Bond Diamond Core Drills for Glass, Ceramics, and Other Hard Non-Metallic Materials)


Starlite metal bond diamond core drills are the finest core drills manufactured in the world. Diamonds held in a metal matrix bond for core drilling glass, alumina quartz, ruby yag, silicon and other hard abrasive non-metallic ceramics. Starting speed and feed recommendations for glass are shown below:

Feed 20 to 35 P.S.I.

3/32" to 1/2" 2,400 - 1,800 RPM
9/16" to 1 1/2" 1,800 - 1,250 RPM
1 9/16" to 2 1/2" 1,250 -  850 RPM
2 3/4" to 3" 850 - 650 RPM
3 1/4" to 5" 650 - 200 RPM
A unique cutting tool, Starlite metal bond core drills have the highest concentration 150 with 108 cts. of diamond per cubic inch of drill. Starlite's metal bond diamond core drills are engineered and designed to have a uniform mixture of diamond in a metal bond matrix. This high concentration of diamond means both long-lasting drill and a very fast drill through the workpiece. Starlite's core drills require minimum pressure to achieve very fast cycle times through the workpiece. Starlite's unique thin wall design means less pressure on the workpiece, thus chipping and breakout are reduced. Average air pressure 20 to 35 P.S.I., less pressure for hydraulic.

Higher speeds may show increased performance.

For information on dressing core drills, ask for "Starlite Metal Bond Diamond Core Drill, Drilling and Dressing Procedures."
