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

Please Note:
Test for centering by sliding one of the prong stop
guides over the bur and into the hole in the L-bracket.
f the guide slides easily through the hole in the
I
L-bracket, the alignment is correct. The bur does not
need to be perfectly centered, but it should not rub on
the guide. The hole in the L-bracket is slightly larger
than the threaded portion of the guide to adjust for
minor variations in centering.
Installing Accessory Guides
Step 1:
Loosen the shaft locking screw and slide the shaft and
L-bracket assembly out from the bur. Slip the rear guide lock
nut over the bur (Figure 6). Slide the shaft and L-bracket back
into the body and tighten the shaft locking screw. It’s important
to tighten the shaft locking screw before aligning the guide
since the shaft will lift slightly when the screw is tightened.
Step 2:
To install a channel-setting guide or other accessory, slip the
guide over the end of the bur and into the hole in the L-bracket.
Tighten the rear guide lock nut to secure the guide, making sure
the guide is centered around the bur.
Step 3:
Loosen the shaft locking screw which allows the shaft to
slide freely. Adjust the guide using the shaft adjusting nut so
the bur protrudes from the guide (Figure 7). To change the
distance between the guide and the cutting edge of the bur,
adjust the guide using the shaft adjusting nut. Tighten
the shaft locking screw.
Please Note:
The smaller of the two basic channel-setting guides (see
page 12) is designed for use with small burs that have
tapered shafts below the bur head. Because the tip area
of the small channel guide is less than the 3/32
bur shank,
the guide will not allow burs to slip or go deeper

The Easy-Cut Prong Guide
The AllSet®Easy-Cut Prong Guide helps ensure straight, uniform cuts on
each prong—every time! It’s completely adjustable and it positions the
setting precisely so the bur won’t grab or roll itself around the prongs,
ausing scratches. It adjusts to any stone shape and size. Perfect for 45°,
c
70° and 90° cuts, it allows you to cut perfect seats in the prongs of large
pendants, basket settings, solitaire mountings and much more.An
adjustable guide in back controls the depth of cut as well.
Use the Easy-Cut Prong Guide to:
• cut perfectly level stone seats regardless of the setting shape.
• gain precise, accurate control over the depth of cut so that finished
prongs are stronger.
• reduce stone breakage because you don’t have to force prongs
while setting.

As the bur rotates, it creates a counterclockwise force on the prong. The prong
guide allows movement only along the
guide’s edge.

prongs so they are the same height and level with one another.
2. Choose a low-speed bur that will make a cut appropriate for the
stone (usually a 90° hart bur). Fine-cut, low-speed burs will work
the best without chatter and skip.
3. Make the cuts by moving the prongs across the bur, perpendicular
to the inward direction of the cut. Cut about a third of the way
into the prong, depending on how thick the prongs are.
Many large colored stones have extra-thick girdles or some other irregularity. You will have to judge if cuts need to be wider or at different levels. Be
sure to mark the stone and the setting for position as you try the fit and
make adjustments. Well-cut stones benefit from settings made with AllSet
guides because there is little or no unusual torque or pressure from
uneven cuts.

Pavé Guide Set
The AllSet®Pavé guides make it quick and easy to create the field-of-
tones effect of pavé.
s
• Includes seven pavé guides, 2–5mm, in 0.5mm increments.
• Solid, non-rotating guides let you complete rows of settings in a
very short time and at the perfect depth for the material.
• Guides accept all 3/32″ (2.35mm) shank burs such as ball burs,
setting burs and hart burs.
Pavé Setting
Step 1:
Determine the diameter of the stones you will be using, making sure all
stones are the same size. Scribe the material with a crosshatch of lines
that are only slightly further apart than the diameter of the stones. This
pattern is usually a 60° offset design (Figure 9) but can be a square pattern. In any case, each line intersection must be slightly more than the
diameter of the stone from the closest adjacent intersection.
Figure 9
Figure 10
Step 2:
At each line intersection, drill through the material with a small drill
(smaller than the stone). This hole will provide a guide for the bur you use
to make the seat.
Step 3:
The AllSet pavé guide will provide a stop for the bur, making all the seats
exactly the same depth. Select a bur (usually a setting bur) the same size
as the stone. Choose one of the pavé guides that is a little larger than the
bur head.

with greater accuracy. Each prong is cut to precisely the same depth so the

• 13 adjustable depth prong-setting guides allow you to use bur

Prong Setting
Step 1:

same. The distance between opposing prongs should be adjusted to
slightly less than the diameter of the stone at the height on the prongs

3
/32″ (2.35mm) shank burs.
Figure 11
Step 2:
Choose a setting bur that is just slightly smaller than the stone’s
diameter (too small a bur increases the chance that the bur will grab
and skip). The best burs are non-aggressive, fine cut burs. Select the prong
guide closest to the bur size that allows the head of the bur to fit down
inside the guide.
Step 3:
Mount the prong guide in the AllSet L-bracket (Figure 11). Insert the bur
through the guide and into the handpiece chuck. Tighten the chuck to
secure the bur.
Step 4:
Loosen the shaft locking screw and adjust the shaft with the shaft
adjusting nut so the shoulder of the bur is at the desired cut-depth below
the guide (Figure 12). You can always cut deeper, so set the depth less
rather than more for the first cut. The depth of the cut should end up
being a little deeper if the stone has a thick girdle.
Step 5:
Hold the setting securely and make sure you approach the prongs as
straight in as possible. Holding the setting with your fingers allows the
setting to move and align itself as the prongs come in contact
with the guide.

Channel-Setting Guides
Figure 13
Cut continuous channels on
straight or contoured pieces.
The AllSet®channel-setting guides allow you to cut perfect channels with
precisely the same depth on each side of the channel for level stone
setting. The set includes three adjustable depth channel-setting guides
for all channel-setting applications.
• The rounded tips of the two basic guides (small and large) make it
easy to cut continuous channels on straight or contoured pieces
(Figure 13).
• The new double knife-edge guide ensures perfect spacing of
separated stones.
Please Note: The smaller of the two basic channel setting guides
is designed for use with small burs that have tapered shafts below
the bur head. Because the tip area of the small channel guide is less
than the 3/32
″ (2.35mm) bur shank, the guide will not allow burs to
slip or go deeper into the channel. Burs cannot be removed or inserted
from the front of the small guide.

Channel-Setting Tips:
Square Stones
For setting stones that will touch, you can cut a continuous channel
(Figure 13):
Step 1: Choose a hart bur with a diameter that will cut a channel to the
proper depth in the material for the diameter of the stones you are using.
Step 2: Select one of the two basic channel guides (small and large ) for
the size bur you are using (see note above).
Step 3: Adjust the distance between the guide tip and cutting edge of
the bur to the desired position of the channel.
Step 4: Cut each channel, making sure to keep the handpiece
perpendicular to the material.
Round Stones (using the knife guide)
