Boring Bar Sets
Borite brand boring bar set (USA) that uses
TPMM22_ carbide inserts. 1/2"
ground shanks.
Carbide boring tool bit sets with
precision ground 1/2", 3/4" &
3/8" shanks.
QCTP Boring Bar Holder
This quick change tool bit holder also has a
V-notch to hold a round (3/8") boring bar shank.
The set screws mar the shank making it difficult
to insert into precision holders
e.g., a boring head.
This AXA quick change boring
bar holder holds a 3/4" shank tool.
Sleeve Adapters
This 3/8" round to 1/2" square, slit, steel
adapter eliminates
set screw marring on
the shaft. The hole was reamed for a
close precision fit to a ground shank.
This supplied sleeve accessory adapts 3/4" to 5/8"
shanks for the quick change
tool post boring bar holder.
A 3" long, steel, 3/4" to 1/2" adapter.
The hole
was precision reamed & the single
slit is 1/8" wide.
The left bolt clamps the adapter body while the right
bolt clamps both the
adapter & the boring bar shank.
Rigid holder & excellent boring bar performance.
A 1/2" to 3/8" boring bar adapter
can be added for even smaller shanks.
Boring
Head in Tailstock
A 2" diameter
boring head with an MT2 (screw-on)
arbor can be used
in the 9x12 lathe's tailstock.
A taper cut is setup with the material held by two
dead centers & driven by a
faceplate
with a dog.
Boring a Plastic Part
Made a
Delrin spacer for a Blizzard rifle
scope
lens hood.
I cut the outside
dimension then quickly removed a lot of
ID material using a large
1-1/2"
drill bit.
Bored the inside dimension. Delrin cuts
smoothly & precisely
with no wear to tooling.
Cutting-off the part.
The cover is installed on the
scope with the spacer inside.
Boring Bars
Boring bar set: 3/8", (2) 1/2" , 5/8", 3/4" & 1"
diameters.
3/8" holds 3/16" round tool bits; others hold various sized
square bits.
Each bar holds bits either perpendicular or at
a 45 deg angle.
Good for inside boring & inside threading.
