Details
Excellent quality metric twist drills from Germany. Made of high speed steel with shank size same as drill. Bright finish, with exactly the proper cutting angle at the tip. Flutes are sharp with the proper spiral and finished outer edges.
Available in 12 sizes from 0.50 to 1.60mm diameter. Each size sold in packages of 10.
(Also sold in a comprehensive Set of 120, see "Related Products" below.)
Tech Tips
It happens to everyone, a drill bit breaks and the business end is stuck inside the hole in your precious metal jewelry. If you can't reach it, how will you get it out? Place the ring into common Pickling Solution. The drill bit will dissolve in about 15 minutes.
(Caution: do not put stones into Pickling Solution.)
