[Source] hollow-core diamond drill bits

Jewelry Discussion
1

Can anyone recommend a source for purchasing hollow-core diamond
drill bits with shafts that will fit the flex-shaft. At a good
price…

I’ve bought them through Rio for outrageous cost; have pursued
advertisements by other suppliers, only to find their prics are
good, but the shafts too large.

will appreciate any suggestions. Tracy Munn munnt@bc.edu

Try Kirk Brock of Rock Solid Jade.
PO Box 10286
Albuquerque, NM 87184
505-890-1587

Kirk has been overseas and I’m not sure if he’s back yet. He’ll
also be in Tucson at the 4 Points Hotel, if you make it to the
show.

Tracey, The stained glass industry has several different types
and sizes. One of the main manufactures is MIKA International.
Their phone #1-800-526-2030. I don’t know if they have a web
site. But a search of stained glass sites asking for diamond
bits should get you several hits. My wholesale glass, etc.
source is Sunshine Glassworks, Buffalo, NY 1-800-828-7159, they
can help you too. Happy Grinding, Leslie

You can try a dental supply house. There were some techniques
used in dentistry which included hollow core or trephining burs
and they are undoubtedly still around. JZ Dule
