Two sets of tool heads are available:
• One set of five tool heads bore 4.5–12"
(114–305 mm) diameter.
• The optional large boring head features a
split-body mounting hub and two sets of tool
arms that bore 12–24" (305–610 mm) diam-
eter.
Tool bits are 1/2" (12 mm) square. Other tool head
options are discussed in Section 3.3.2 on page 35.
2.3.6 BB4500 boring bar
Standard BB4500 bars are 1.75" (44 mm) in diameter and are available in lengths
from 4–12 ft (1.2–3.66 m) in 24" (610 mm) increments. Contact CLIMAX for bars
of other lengths and diameters.
All bars have 0.5" (12 mm) square tool bit mounting holes spaced at 10" or 6" (254
or 152 mm) intervals. Contact CLIMAX for custom hole spacing patterns.
Do the following to determine the bar length required (see Figure 2-14 on page
26):
1. Determine the workpiece overall dimension + stroke + 27" (686 mm).
2. Round up to the next 24" (610 mm) increment.
2.3.7 BB5000 boring bar
Standard BB5000 bars are 2.25" (57 mm) in diameter and are available in lengths
from 4–12 ft (1.2–3.66 m) in 24" (610 mm) increments. Contact CLIMAX for bars
of other lengths and diameters.
All bars have 0.5" (12 mm) square tool bit mounting holes spaced at 10" or 6" (254
or 152 mm) intervals. CLIMAX offers a drill jig with a tool sleeve kit for cutting
intermediate tool bit holes for special applications. Contact CLIMAX for custom
hole spacing patterns.
Do the following to determine the bar length required (see Figure 2-14 on page
26):
1. Determine the workpiece overall dimension + stroke + 27" (686 mm).
2. Round up to the next 24" (610 mm) increment.
