The Faces of Perma-Grit
Great Tools for Great
The perfect straight edge! Placed on its side, this
block's sanding face is 0.5 mm above the table, allowing it to be used for
squaring off materials, or producing the perfect dihedral angle. They can be
used to block sand large areas, profile leading edges and feather trailing
edge. Coarse and fine grits are permanently bonded to a custom made aluminum
extrusion. Light and easy to grip they will never warp. The unique safe edge
will protect the sanding face against damage. WB-140, SB-280 (11"
length), SB-560 (22" length)
Spar Slotters -
Perma-Grit has re-introduced these very useful spar slotting tools
in 3 convenient sizes.
6" long steel bars have the Tungsten Carbide course grit bonded to one side
allowing neat, true slots to be cut into plywood, balsa or composite formers
and ribs. Two sizes available, SP9C has been discontinued.
3mm or 1/8" #3c
6mm or 1/4"
No need to glue sandpaper to
dowels anymore! The handle is a smaller radius than the cutting face, making
these tools perfect for wing fillets, tail fillets and all concave curves. Use
them for openings on both plastics and fiberglass cowlings, etc. Perma-Grit
will not cause paint to chip or flake off when modifying a finished item.
Remember, Perma-Grit cuts foam, wood and glue joints all with ease. R-200,
R-202, R-203, R-204
Used for shaping and finishing corners. Either a 1/8
radius or sharp corner can be produced simply by rotating the tool. The width
is less than a standard servo, making it ideal for fabricating servo trays. It
is also useful for making internal corners of formers, doors, hatches, etc.
One-half of the tool is coarse grit, the other fine.
Turned down from steel and coated in tungsten carbide
grit, these rotary files are well balanced. The drum can be used for making
wheel wells and servo cut outs, etc. because it cuts on the end face as well as
the sides. All rotaries are ideal for routing, shaping and removing materials
without tearing or clogging. These tools are available in a coarse and fine
grit (RF-7 and RF-8 available in coarse
only).RF-1 to RF-10
Made from tungsten carbide
brazed to a mild steel base, these files are virtually unbreakable. Unlike
conventional needle files, these will cut plastics, softwoods, hardwoods,
fiberglass, ceramics, etc. The unique abrasive coating means they cut in any
direction. Five shapes are available complete with a Swiss file handle for
additional grip. NF-1, NFH-1
Unbreakable tungsten carbide
discs are available in 2 sizes. They are tough enough to cut piano wire as well
as fiberglass, plastics, all woods and ceramics. The discs are available in
3/4" and 1-1/4" diameters complete with 1/8" stainless steel arbor and fit
Minicraft, Dremel, etc. Remember: Always wear safety goggles when using rotary
tools! RD-1, RD-2, RD-3
Much thinner than the other Perma-Grit hand tools, these
are thin enough to be bent to any shape, internal or external. They can be
mounted to a solid base using epoxy or super glues allowing complex curves to
be easily fabricated. FXT 103 (fine), FXT 104
Thin flat files can be used
to clean up slots, cut outs in formers and general sanding where the blocks are
too large. The 6 mm square (S-204) Perma-Grits can be used for making spar
slots, mini/micro servo trays and internal corners too small to be made with
the R-201. Use concave tools to form leading edges, etc. on wings, tail planes
and to radius any sharp corners. They are available in coarse or fine grit.
F-101, F-102, R-200C, R-201C, R-202C, R-203C, R-204C, R-204F, S-204C,
S-204F (C = coarse grit, F = fine grit)
We recommend using a DIY
paint stripper because it is a much stronger solvent than paint thinners.
Simply apply paint stripper to the surface of the tool, leave for five minutes,
then clean by brushing under running warm water with a brass brush. This
process will remove all paints, resins, epoxy glues, wood sap, etc. but has a
limited effect on super glues. These can be dissolved using a standard
NOTE: All hand tools are uniformly
sprayed with a thin coat of paint. This will be removed either by using the
tool or cleaning with solvents, leaving the copper or nickel braze color on the
surface. The tungsten grit will not be affected.
