Boring head assembly
The boring head assembly
mounts to a 4" or 5" tool
carrier. Set desired boring
diameter range using the
spacers provided. Includes
two styles of carbide tool
holders for versatility.
Leading and trailing tool
holders permit heavy boring.
Assembly requires either the
4" or 5" tool carrier (P/N
15567 or 16822).

Facing head assembly
Mounts onto either the 4" or
5" tool carrier assembly. On
the 4" tool carrier, the facing
head will face diameters from
9.5" to 35" (241.3 to 889.0
mm). On the 5" tool carrier,
the facing head will face 10.5"
to 36" (266.7 to 914.4 mm)
diameters. Set the facing
range using the spacers
provided. The facing head
features mechanical radial
feed with a 4" (101.6 mm)
stroke. Adjustable feed rate
up to .010" (.254 mm) per
revolution. Assembly requires
either a 4" or 5" tool carrier
(P/N 16822 or 15567) and
1/2" square tool bits.
