The Allset prong, pavé and channel-cutting guides in this kit deliver precise,
repeatable accuracy and flexibility whenever they’re used. The result is higher
quality, defect-free stone settings done faster and easier than ever before!
Here’s what you’ll find with your Master Stone-Setting kit:
Non-Rotating Guide Assembly. This lightweight assembly is the heart of the Master kit. It attaches easily to a Foredom
H.30®handpiece and includes body, collar, shaft and L-bracket.
The Easy-Cut Prong Guide. Create level, uniform and precise cuts time after time with this remarkable prong-cutting aid.
Its unique design ensures a level and uniform-height cut on square, round or any other shape of prong. It also includes a new
stop guide that precisely controls the depth of each cut.
Channel-Setting Guides. Create perfectly contoured channel settings for round, square and baguette stones quickly and
easily with these precision guides. Kit includes three guides (small, large and knife-edge).
Prong Guides. Ensure the proper-depth cutting of prongs in single- or multiple-prong settings with these precise guides.
Includes 13 separate guides.
Pavé Guides. Let you create the cobblestone effect of pavé in half the time it would take by hand. Includes seven stainless
steel guides.
Allset Quality. Allset kits and components are made in the USA of highly durable materials and are versatile tools that stand
All of the cutting guides are made of the

Introduction
The patented AllSet®guide assembly is a lightweight attachment 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 handpiece 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.

Step 2:
Hook the front of the AllSet guide body over the front lip of the
handpiece housing, opposite the chuck key opening (Figure 2).
Lower the back of the AllSet body until it is flat against the
H.30®handpiece.
Please Note:
Be sure the front of the AllSet body is attached to
an unbent, undamaged section of the housing lip.
If the AllSet body does not lie flat on the handpiece,
it is not hook
ed properly over the housing lip.
Step 3:
Slip the collar over the back of the handpiece and AllSet body,
then push forw
ard against the handpiece housing (Figure 3).
Make sure the bevel on the inside edge of the collar is
facing forward.
Step 4:
Turn over the handpiece, body and collar assembly (Figure 4).
Screw in the shaft locking screw just enough to make sure it
is in the hole at the back of the body. Do not tighten it all the
way or the shaft will not slide completely into the body (see
Step 7). This screw is used to lock the shaft in position and does
not function to secure the collar on the body or handpiece.

Step 5:
While holding the body against the handpiece, push the front
of the body toward the collar to be sure it is still hooked over
the front lip of the handpiece housing. Evenly tighten the two
set-screws until the collar is centered from side to side on the
handpiece and the AllSet body is firmly against the handpiece
housing. Snug down the set-screws with the Allen Key included
in the kit. Do not over tighten.
Step 6:
Insert a 3/32″ (2.35mm) shank diameter bur in the handpiece
chuck (F
igure 5).
This bur will act as a reference for aligning the
AllSet guide. Since you will slip a guide over the bur, be sure
the bur head is smaller than the shank which is 2.35mm. A
2mm round bur is suggested.
Step 7:
Assemble the shaft adjusting nut and L-bracket as shown.
Insert the shaft (grooved end first) into the body of the
AllSet
(Figure 5). Loosen the shaft locking screw enough to allow the
shaft to slide past the locking screw. The bur should go through
the center of the hole in the L-bracket. Tighten the shaft
