Dremel Accessories
The number and variety of accessories for the Rotary
Tool are almost limitless. There is a category suited to
almost any job you might have to do — and a variety
of sizes and shapes within each category which en-
ables you to get the perfect accessory for every need.
Refer to the DREMEL ACCESSORY ORDER FORM for
illustrations of the accessories available. These
accessories may be found at your local hardware,
hobby or home center dealers.
Collets
If you expect to use a variety of accessories, we recom-
mend that in the beginning you purchase a complete set
of four collets. Store these so that you will have the
proper size of collet for any accessory or drill bit you
want to use. Currently, the 1/8", 3/32",1/32" and 1/16"
collets accommodate all of the available Dremel
accessories. 1/8" collets are included in most rotary
tool kits.
Mandrels
A mandrel is a shank with a threaded or screw head,
which are required when you use polishing acces-
sories, cutting wheels, sanding discs, and polishing
points. The reason mandrels are used is that sanding
discs, cutting wheels and similar accessories must be
replaced frequently. The mandrel is a permanent
shank, allowing you to replace only the worn head
when necessary, thus saving the expense of replacing
the shaft each time.
Screw Mandrel No. 401
This is a screw mandrel used with the felt polishing tip
and felt polishing wheels. 1/8" shank.
Small Screw Mandrel No. 402
This is a mandrel with a small screw at its tip, and is
used with emery and fiberglass cutting wheels, sand-
ing discs and polishing wheels. 1/8" shank.
Threaded Tip Mandrel No. 424
This is a mandrel with a threaded tip which threads into
the polishing point accessory No. 427. 1/8" shank.
High Speed Cutters
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 carv-
ing in wood or plastic, and for precision cutting. Made
of high quality steel. 1/8" shank.
Tungsten Carbide Cutters
These are tough, long-lived cutters for use on hard-
ened steel, fired ceramics and other very hard ma-
terials. They can be used for engraving on tools and
garden equipment. 1/8" shanks.
Engraving Cutters
This group has a wide variety of sizes and shapes, and
are made for intricate work on ceramics (greenware),
wood carvings, jewelry and scrimshaw. They often are
used in making complicated printed circuit boards.
They should not be used on steel and other very hard
materials but are excellent on wood, plastic and soft
metals. 3/32" shank.
Structured Tooth Tungsten Carbide Cutters
Fast cutting, needle-sharp teeth for greater material
removal with minimum loading. Use on fiberglass,
wood, plastic, epoxy and rubber. 1/8" and 1/4" shank.
Aluminum Oxide Grinding Stones (red/brown)
Round, pointed, flat — you name the shape and there is
one available in this category. These are made of alu-
minum oxide and cover virtually every possible kind of
grinding application. Use them for sharpening lawn
mower blades, screwdriver tips, knives, scissors, chisels
and other cutting tools. Use to remove flash from metal
castings, deburring any metal after cutting, smoothing
welded joints, grinding off rivets and removing rust.
These grinding stones can be resharped with a dressing
stone. In machine shops, high speed drills and cutters
normally are ground with aluminum oxide wheels. 1/8"
shank.
Silicon Carbide Grinding Stones (blue/green)
Tougher than aluminum oxide points, these are made
especially for use on hard materials such as glass and
ceramics. Typical uses might be the removal of stilt
marks and excess glaze on ceramics and engraving on
glass. 1/8" shank.
Diamond Wheel Points
Excellent for fine detail work on wood, jade, ceramic,
glass and other hard material. Bits are covered with
diamond particles. 3/32" shanks.
Use only Dremel Tested, High Performance Accessories. Other accessories are not
designed for this tool and may lead to personal injury or property damage.
