Diamond encrusted burrs: Available in many shapes, high
speed cutters are used in carving, cutting and slotting in
wood, plastics and soft metals such as aluminum, copper
and brass.
These are the accessories to use for freehand routing or
carving in wood or plastic, and for precision cutting. Made
of high quality steel. 1/8" shank.
Grinding stones: Use for surface treatment of metal parts,
cast-metal parts, welding seams and for the removal of rust.
Different shapes are available.
Cutting-off wheels: Use to cut work-pieces made of
metal, plastic, wood or stone. Use one of the provided
mandrels to assemble. The cutting-off wheel only cuts with
the outer edge.
Dressing Stone: Use for cleaning and whetting grinding
stones, if their surface has become irregular or dirty.
Drum Sander: Use to grind or smooth workpieces made of
wood or glass fiber material. Use with the provided grinding
drum.
POWER TOOL OPERATION
Mandrels: Shafts with screw or threaded head, which are
designed for retaining grinding and polishing wheels. Drill
bits: Use for drilling holes in work-pieces made of plastic,
wood or metal.
OPERATING SPEEDS
To select the right speed for each job, use a
practice piece of material.
NOTE: Speed is affected by voltage changes. A
reduced incoming voltage will slow the RPM of
the tool.
Your tool is equipped with a variable speed dial. The speed
may be adjusted during operation by presetting the dial on
or between any one of the settings.
Certain materials, however, (some plastics and precious
metals, for example) require a relatively slow speed because
at high speed the friction of the accessory generates heat
and may cause damage to the material.
Slow speeds (15,000 RPM or less) usually are best for
polishing operations employing the felt polishing accessories.
They may also be best for working on delicate wood carving
and fragile model parts. (All brushing applications require
lower speeds to avoid wire discharge from the holder.)
Higher speeds are better for carving, cutting, routing,
shaping, cutting dadoes or rabbets in wood.
Hardwoods, metals, and glass require high speed operation,
and drilling should also be done at high speeds.
