NOTES: [1] ONLY Tungsten
Carbide may include this
specification. All other materials CANNOT
include this
specification. [2] Minimum
diameter for Beryllium Copper is
.020. Material has been spring-temper
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. 312-345 becomes
312-345-1).
