Mandrels
A mandrel is a shank with a threaded or screw
head, which are required when you use
polishing accessories, 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 per-
manent 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. 3,2 mm
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
carving in wood or plastic, and for precision
cutting. Made of high quality steel. 3,2 mm shank.
Tungsten Carbide Cutters
These are tough, long-lived cutters for use on
hardened steel, fired ceramics and other very
hard materials. They can be used for
engraving on tools and garden equipment. 3,2
mm shanks.

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 aluminum 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. 3,2 mm shank.
