Stone
Sculpture Power Tool Options
Electric Tools
1). Electric Drill - buy cheapest, faster RPM possible because you will
burn it out.
It can be used :
To drill holes
with masonry drill bits
With carbide and diamond
burrs for slow removal of stone if you
don't have a die grinder
To sand with "stick
and sand" padded sanding disc pad
(use additional rubber cement to glue disc to pad) (local hardware
store) good for sanding large areas. Use 4"or 4 1/2"pad.
2). Electric Die Grinder (Harbor Freight.com , Toolbarn.com) can be used:
Used
to remove stone in areas where breakage is a problem and to carve the form.
1/4" shank size ....for most work
Used with accessories: Carbide Burrs
and Diamond Burrs good for carving - coarser
grit the better- AND rotary chisel to remove large amounts of
stone .

3). Angle Grinder can be used:

*
To remove large amounts
of stone by cutting slices into the stone
with grinding wheels or diamond blades and using a hand held mallet
and chisel to knock the pieces loose. Diamond blades (Braxton
Bragg, Knoxville)
* To carve and shape the sculpture
(especially soft stones)using the masonry discs available at local
hardware stores
4). Foredom
Flexible Shaft Tool
Great for detail carving - I use the S series motor and #25 handpiece
but they may have a more powerful one now - Accessories include
steel, carbide and diamond burrs. Will take 1/4" and 1/8"
shanks. I tend to use only the smaller burrs for detail work.

Pneumatic
Tools
1).Handpiece or Hammer
1/2" to 3/4"shank - needs at least a 2HP
compressor to use.
3 1/2 HP better. There are three brands most used. Italian (Cuturi)
(Milani) and American.(Trow and Holden). The Italian is smoother
and less heavy. with less vibration. but many like the power of
the American. It uses PSI from 20 to 100 (costs about $300)
2). Pneumatic
Chisels
Tooth chisels are especially good
for shaping alabaster and limestone. Points, flat chisels and
tooth bullnose available. Bush chisel great for texturing marble
as well as stone removal.. Carbide tipped last longer and are
more expensive. They are a must for marble.
3). Air

doesn't get hot. Needs 90 PSI. on compressor to use. Uses all
accessories of electric die grinder. (Home Depot has a cheap one,
