"IN APPLICATIONS LIKE THIS
MODERN PRECISION INJECTION PLASTIC IS
REPLACING METAL THE SAME WAY
INTEGRATED CIRCUITS REPLACED TRANSISTORS"

All hand pieces on the market today with the exception of the Turbo Carver II, are made using 40 year old technology. Turbo Carver II uses cutting edge technology and is a radical innovation in Ultra High Speed hand piece design.

Our instrument weighs only 1/2 ounce. It can be used by people with arthritis and other joint maladies because there's no weight, vibration or torque transmitted to the handle. If you accidentally drop a metal hand piece, there is a good chance you will destroy the bearings or break the bur. Turbo Carver II is so light, it resists breakage if dropped on the floor.

Because Turbo Carver II is made from precision injection molded plastic it could be designed small and simple. It has been said and demonstrated that simplicity is elegance. The small, pen-like, size also increases your visibility and improves access in hard to reach areas

"IT IS THE ONLY INSTRUMENT
WITH A COMFORTABLE
TEXTURED RUBBER GRIP"

Plastics are not affected by moisture, which is a serious problem for metal instruments. Hand pieces with aluminum handles are very susceptible to oxidation from moisture coming through the air lines. Oxidation is what sand paper is made from and it will destroy the bearings if it forms within the hand piece. For this reason, metal hand pieces, require an expensive moisture trap installed in the air line. Unfortunately, the moisture trap will not prevent water vapor from getting into the hand piece while working with water as needed for hard materials.

Turbo Carver II uses a one piece, carbon composite turbine assembly. There is no costly chuck to wear out and no wrench is necessary. Since there are fewer parts concentricity is superior to its metal counterparts thus reducing vibration and noise. Concentricity of the new turbine is between 0 and .0002".

NOTE: Don't let its small size and low weight fool you, this instrument is as good or better in performance than the larger, heavier and much more expensive metal counterparts.

Dirty drive air is the cause of many bearing failures. Turbo Carver II comes with a 5 micron air filter, in-line with the foot control, which removes any oxides or minute particulates, that get through the main regulator water trap/filter.

Turbo Carver II incorporates a miniature in-line air pressure gauge. This gauge is used to determine with more accuracy, the optimum setting on your air compressor regulator. Too little pressure and you won't get good results, too much and you risk destroying the hand piece. You can not rely on the gauge on the compressor because vibration and age reduce their accuracy. Also, pressure is lost in the tubing that goes between the regulator and hand piece. As much as 1 PSI can be lost per linear foot of tubing.

All ultra high speed air-driven hand pieces have an inherent problem. They draw contamination into the front bearing whenever you operate the instrument. The effect is called Carman Street Vortex and is a leading cause for bearing failure. This means when the drive air to the turbine is shut off, it takes several seconds for the turbine to spin down. During this time the turbine becomes a vacuum pump and pulls airborne contamination into the bearings. Turbo Carver II has solved this problem with a patented pinched valve/air regulator mounted on the exhaust port. This regulator maintains positive pressure within the turbine housing during shut down, thus preventing a vacuum from forming. Once the hand piece is turned off and set down, the one-way valve closes shut thus preventing dirt from entering through the exhaust port.

The second cause for bearing failure is heat buildup in the rear bearing. During operation air passes through the front bearing because of the path available around the spindle. However, there is not enough pressure within the turbine housing to get a good air flow around the rear bearing. The pinched valve on Turbo Carver II increases the operational pressure within the turbine housing. This increased pressure makes it possible to create an air flow around the rear bearing.

The third reason for bearing failure is caused by the lubrication process. Manual and automatic lubrication is an imprecise procedure and too much oil is as bad as too little. Also, no matter how careful one is it is inevitable that dirt is going to be introduced during lubrication. Turbo Carver II uses the most advanced bearing technology available to eliminate the need for external lubrication. The bearings used in this instrument are Lubricated For Life and because of this the bearings will last much longer. We have recently increased the warranty on the bearings from 3 to 6 months and additional testing will probably increase the warranty to 1 year in the near future.

Turbo Carver II operates at 450,000 RPM making it the fastest in the world. The faster this type instrument turns, the better it works.

Our instrument is the only one that will operate on both compressed air or as an option, bottled CO2. CO2 has the advantage of being less expensive than an air compressor, weighs less and is therefore easier to haul around. CO2 does not require electricity and is totally quiet. This makes it easy to work in remote locations or places where power is not available; it's ideal for trade shows.
