Spot/center drill follow-up
Several posters in the recent spot/center drill thread indicated
an interest in using spotting drills to both spot and
countersink/chamfer the drilled hole.
I just received the September Enco "hot deals" flyer, and they
have several types of spotting drills on sale made from M2 or M42
with different angles/sized including 82, 90, 118 and 120 degrees
on page 20. [60 degree also available but not on sale, as are
carbide -- see main catalog]
For our RCM readers Edward's books on manual engine lathe and
turret mill operation are also on sale on page 66. These are
very good introductory level books, with several useful projects.
