hardened. [3] Customer
Supplied material must be hard enough to allow
grinding. Material must be supplied
with correct diameter specifications.
Extra material will be required to
accomodate failure
rate. [4] Standard
tips are spherical. For FLAT TIP, specify
"-1" at end of part number (e.g. 31-2345 becomes
31-2345-1).
