No. I found them at their manufacturers, called
DrillMatic Drill shaft and countersink, apparently
made out of carbide. Have a price request in at
the company. Got these with about 350 specialty drills,
all kinds of weird ones, super long ones, Forstners, just
lots and lots and lots of drills from tiny to huge.
Had to pay a lot .......... $10, tho, so they must be good
quality.
