NOTES:
[1] ONLY Tungsten
Carbide may include a 5 degree tip angle.
All other materials CANNOT
include this
specification.
[2] Beryllium
Copper minimum diameter is .020. BeCu
material has been spring-temper hardened prior
to grinding.
[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)
