Gunther TBH Pro 3 Diamond Drill Press For Stone - Glass - Ceramic
Introducing the New TBH Pro 3 Diamond Drill Press from Gunther Diamond Tools - The world's best water-cooled small-diameter diamond core drilling system for lapidary, gemstone, and precision industrial drilling.
It's the ultimate gemstone and lapidary drill press and a better alternative to ultrasonic drilling for most situations. It's professional-grade yet easy enough for DIY projects like drilling holes in glass, porcelain, and ceramic.
Drilling with water is the safest and most effective way for consistent results every time. The water feed runs through the center of the core drill bit, so you are continuously ejecting the cut material and drilling a clean surface.
As the newest advancement in the TBH Pro lineup, this system builds upon our successful TBH Pro 2 system with three new features.
Water Guard Sensor
The water guard sensor indicates that your machine is experiencing a leak, with an internal sensor that triggers a signal light and an audible alarm. With this safety measure, you can react immediately and protect the machine from damage by shutting it off and drying it out.
In the previous design, a water feed pipe is held in place with a nut and collet system. If the nut holding the water pipe in position is loosely tightened or not tightened at all, it can lead to "flooding" of your machine when you turn on the water supply.
The TBH Pro 3 Drill Press now has the Flooding Stop bracket that secures the water pipe into position, regardless of whether the nut and collet are tightened, to prevent flooding.
Stainless Steel Precision Shaft
The brass center shaft has been replaced with a precision shaft made of stainless steel. This upgrade provides higher stability, durability, and longevity.
Key product details at a glance
With the TBH Pro 3 Bench Top Drill Press, you can precisely drill various materials such as quartz, glass, ceramics, or solid carbide with diamond core drills and a water feed system that flows through the center of the drill bit.
The TBH Pro 3 wet drill press retains all the successful features of the TBH Pro 2 wet drilling machine, like the Gunther Water Feed System, Gunther Alignment System, and our proprietary Sintered Diamond Core Drill Bits.
It is still built on the Proxxon drill press platform with the mechanics of the Gunther components modifying the Proxxon drilling unit. This modification results in a short distance between the chuck and the end of the drill bit, which increases drill bit stability and results in less runout and better precision.
The compounding effect of these Gunther Features creates a unique wet drilling system that delivers precision consistently. The powerful TBH Pro 3 Diamond Drill Press is the first choice for successfully performing demanding drillings on sensitive materials!
The drill has a powerful 220 - 240 V-permanent-magnet motor and a spindle drive via a 3-time band pulley with poly-V-bands. This setup gives the advantage of almost 6-time torque in the lower speed range (for large drilling diameters).
It also incorporates a spindle sleeve feed for delicate work, a practical drill depth display with an adjustable end stop, and a precisely located drill spindle.

- **Krieger 350-Watt Transformer - This professional-grade voltage transformer can be used in 110-volt- and 220-volt countries. It will convert from 220-240 volts to 110-120 volts AND from 110-120 volts to 220-240 volts.
**Please note this unit is manufactured in Germany for the European 220v grid and comes with a European plug. To operate this system in the USA, you must use a transformer to convert the USA 110v system to the European 220v system. We have included a Krieger 350-Watt Transformer to make this conversion.
