I use the Lindsay Classic AirGraver, and swap out to the Badeco when
I need more horsepower. I also have a couple of GRS Gravermaxes with
the 901 handpiece and a Swiss hammer handpiece. In order of ability
to wallop metal, they go from the Badeco which can hit the hardest by
far, especially with a geared motor, to the Swiss, to the Lindsay
(with the optional tungsten piston) to the GRS, which is a little on
the wimpy side and isn’t up to hammering thick 18K white gold bezels.
The GRS 901 handpiece can be beefed up with the heavier spring which
makes it almost as powerful as the Lindsay and tungsten piston combo,
but still considerably less than either the Swiss or Badeco
handpieces. But it does so at a cost.
In the controllability and adjustability category, they go in order
from the best which is the Lindsay to the GRS to the Badeco then to
the Swiss. It is worth noting that a good solid-state pedal and a
gear reduced flexshaft like the old Foredom Series EE increase the
control, power and adjustability of the rotary hammers significantly.
In the affordability category, the least expensive is the Swiss
handpiece, followed by the Badeco, then a major jump to the GRS and
finally the Lindsay (with the GraverMach and Magnum handpiece combo
costing more than the Lindsay Classic). I would add that the quality
of the tools (and their lifespan) is mirrored in their prices as
You really can’t go wrong with any of these fine tools, but if
hammering metal is your only need, I would recommend staying with the
flexshaft powered hammers. The extra price for the tools and
compressor isn’t worth it for just a hammer handpiece. If your
compressor is still working Vince, an air powered handpiece remains a
good option, but either the GraverMach or Lindsay without a
compressor will set you back more than double what a new flexshaft,
pedal and handpiece combined costs. And neither one hits as hard.
The air powered handpieces are definitely more adjustable and
controllable, even if they are weaker in the hammering department.
But they have far more usefulness beyond just as a hammer, where the
flexshaft models really do only one thing. The standard mushroom
handle on the air powered handpieces also makes them quite a bit more
user friendly, the super light tube on the Lindsay makes it feel
almost like a plain push graver.
If hammering power is the most important factor, the rotary
handpieces win the contest hands down and the Badeco beats the bezels
out of all of them.
If you are near Durham NC, I’d be glad to let you try all of them
side by side and see if you agree with my assessment.
No affiliation with any of these companies. I just love tools and
banging on metal.
