Impact & Rotary - All In One ArtGraver™
Lindsay Engraving System
The BenchJewel Rotary handpiece is slightly larger in diameter in order to
accommodate the larger turbine, that provides more torque/power.
Size comparison is pictured below.

This disc pedal and rotary handpiece can be attached to the auxiliary
port of the AirGraver regulator.

in the same step with the rotary.
The BenchJewel Rotary holds the dental sized friction grip burs. The
turbine in the handpiece is larger diameter than most dental type rotary
tools such as NSK. Since the turbine is larger it has more leverage and
provides greater torque/power.

Warning - always use the BenchJewel Rotary handpiece with a variable
control pedal. Never operate a precision rotary tool attached to direct
air pressure, or with a pedal that is only an on/off switch, and that is

Referring to the green arrows. Remove the plug screw from the auxiliary
port and insert the hose barb in its place.
2: Push one end of the BenchJewel Rotary tubing to the black plastic hose
barb on the Disc Pedal grey line. The other grey line of the
Disc Pedal you push on to the metal hose barb of the auxiliary port that
you installed in step 1.
If you have an older dual
regulator setup here are the directions for attaching the BenchJewel
Rotary to it.
1: For this setup you will need the two items that the green arrows are
pointing to in the photo to the left. They are: Splitter
$16.00 1/8" Hose barb
2: On the right port of the regulator on the right unscrew the hose barb
along with the line that is attached to it. Screw in the
splitter. Now screw in both the new hose barb from step 1 into one
port of the splitter and screw the hose barb with the line into the other
port of the splitter.

The turbine bearings in the
BenchJewel Rotary are traditional bearings that are more durable than oil
less type bearings. Traditional bearings require oil. If
you are working on a project and are working it hard it is recommended to
give the bearings a drop or two of oil every few hours.
Use the supplied oiler to deliver a
drop or two of oil. To do this:
1:Turn the ring to match the red dot on the body with the lubrication
2: Place a drop of oil by inserting the oil dispenser to the lubrication
3: Next rotate the ring to un-match the red dot on the body with the lubrication
hole, and the tool is ready to go back to work.
Oil does come with the handpiece,
however if you run low more can be purchased. Use the this to
refill the oil dispenser that came with hour handpiece. Rotary Oil, 1oz
To insert a bur. Insert the
shank of the bur in the nose hole. Place supplied insert tool over
the bur. Use it to push the bur the rest of the way in.
To removed a bur use the push plunger on
the end of the handpiece to push the bur out.
Be sure the shank of the
bur is clean and rust free. If there is corrosion or damage to
the shank of the bur do not insert it as it could damage griper in the
Be aware that continuous hard side
pressure on a bur without oiling every few hours will shorten the life of
the turbine bearings. Generally cutting background out as
shown in the video above on this page by Steve Lindsay is considered
fairly gentle use. Be careful not to drop the handpiece. If it
were to land on the nose it could damage the \ bearings or collet nose,
requiring the handpiece to be returned for repairs.
