Introduction
The patented AllSet ® guide assembly is a lightweight attach-
ment that becomes part of a standard flexible shaft handpiece.
When properly installed, you can leave the collar and body
attached to the handpiece while doing other work with your
flex shaft. You may even decide to dedicate an extra H.30
®
handpiece exclusively to the AllSet guide.
To use the AllSet guide, simply slide the shaft and L- bracket
assembly into the body following the assembly instructions on
pages 4 and 5. When the handpiece is needed for another
operation such as polishing, simply loosen the rear shaft
locking screw and slide the shaft out of the body.
Assembling Your AllSet ® Guide
The AllSet tool is carefully engineered to adjust for normal
manufacturing tolerance variations in the handpiece. Therefore,
you need to carefully tune the body of the AllSet to your hand-
piece by adjusting the collar set-screws, using the Allen Key
supplied with your AllSet Master Kit. These minor adjustments
in the collar set-screws will center the hole in the bracket in
front of the handpiece chuck. This procedure is explained in
Steps 6 and 7 of the assembly instructions on pages 4 and 5.
A Note About Burs
As a general rule, cutting seats for stones should be done with
low-speed burs. Vanadium steel burs are an excellent choice
because of their fine-vane design. This gives you greater control
while cutting the seat and helps eliminate the tendency of the
bur to grab and skip. As with most drilling operations, use a
low speed.
To achieve precise cuts during prong-setting, we recommend
using a flexible shaft machine with high torque at low speed
such as the Foredom
® Series L or TX machine with your AllSet ®
tool. For cleaner cuts during channel-setting applications, you
will want to use a smaller bur and run it at a higher speed.
For this, we recommend using the Foredom Series SR.
Before You Start
Detach the H.30 handpiece from the flex shaft. Follow Steps 1
through 7 (pages 4 and 5) to install the AllSet guide assembly
on your H.30 handpiece.

not allow as good a fit.) Flex shaft machines are available separately.
