Full 3/8" (9.5 mm) of Diamond Cutting Surface

CRL PDT Series Metal Bond Diamond Drills use a special diamond and brass bond
for maximum performance in glass. Metal bond drills offer the greatest life,
1000 to 2000 holes in 1/4 inch (6.4 millimeter) glass with proper maintenance
and the use of a wet
Sharpening Stone to expose fresh diamonds, of any type of
diamond drill. PDT Series Diamond Drills use a special diamond and brass bond
for maximum performance in glass drilling. These Italian made multi-layer drills
cut faster and run cooler than any other drill on the market. They have a full
3/8 inch (9.5 millimeter) deep cutting surface filled with diamonds and bronze
bond, which allows for long drill life, but also makes this style drill more
fragile. They should always be used in true running machines on flat glass
surfaces.
These diamond drills feature Belgian style mounting threads (also
known as 1/2 inch (12.7 millimeter) gas thread), which is popular among all U.S.
and European glass drilling machines.
