Bosch Power Tools 400 Series XPR High Speed Cutters, Structured Tooth Tungsten Carbide Cutters

ACCESSORIES (continued)

High Speed Cutters

High speed cutters are 1/8" shank used in carving, cutting

and slotting wood, plastics

and soft metals (such as aluminum, copper and brass). Made of high quality steel.

Structured Tooth Tungsten Carbide Cutters

1/8" shank

These cutters feature fast cutting needle- sharp teeth for greater material removal with minimum loading. Use on fiberglass, wood, plastic, epoxy and rubber.

			speeds		greater than
15,000 rpm. Refer to Speed Settings
(pages 10-12) for proper tool and setting.
Three		different	shapes
of	wire brushes			are
available in three differ-
ent materials: stainless					1/8" shank
steel, brass and carbon
wire.		Stainless		steel
brushes perform well on pewter, aluminum,
stainless steel and other metals, without
leaving rust. Brass brushes are non-sparking
and softer than steel, making them good for
use on soft metals like gold, copper and
brass. Carbon wire brushes are good for
general purpose cleaning.
Bristle Brushes				are	1/8" shank
Bristle		brushes
used for cleaning tools on

silverware, jewelry and antiques. The three shapes make it possible to get into tight cor- ners and other difficult spaces. They can be used with polishing compound for faster cleaning or polishing.

Engraving Cutters
Engraving cutters come in a	3/32" shank
wide variety of sizes and

shapes and are used for intricate work on ceramics (greenware), wood carvings, jewel- ry and scrimshaw. They are often used in making complicated printed circuit boards. They should not be used on steel and very hard materials, but are good for use on wood, plastic and soft metals.

Tungsten Carbide Cutters

Tungsten carbide cutters 1/8" shank are long-lived cutters for

use on hardened steel, fired

ceramics and other very hard materials. They can be used for engraving on tools and gar- den equipment.

Brushing Pressure

•. The tips of a wire brush do the work. Operate the brush with the lightest pres- sure so only the tips of the wires come in contact with the work surface.

•. If heavier pressure is used, the wires will become overstressed, resulting in a wip- ing action. If this continues, the life of the brush will be shortened by fatigue.

•. Apply the brush to the work surface so the majority of the brush face makes full contact. Applying the edge or side of the brush to the work surface will result in wire breakage and shortened brush life.
