Aluminum Oxide Grinding Stones (orange/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, chis- els and other cutting tools. Use to remove flash from metal castings, deburring any metal after cutting, smoothing welded joints, grinding off rivets and remov- ing rust. In machine shops, high speed drills and cutters normally are ground with aluminum oxide wheels.

Silicon Carbide Grinding Stones (green/gray)

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.

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.

Polishing Accessories

These include an impregnated polishing point and an impregnated polishing wheel for bringing metal sur- faces to smooth finish; a felt polishing tip and felt polishing wheel, and cloth polishing wheel, all used for polishing plastics, metals, jewelry and small parts. Also included in this group is a polishing compound (No. 421) for use with the felt and cloth polishers.

Polishing points make a very smooth surface, but a high luster is obtained using felt or cloth wheels and polishing compound.

No polishing compound is needed when using the 425 Polishing Wheel or 427 Polishing point.

Aluminum Oxide Abrasive Wheels

Use to remove paint, deburr metal, polish stainless steel and other metals. Available in fine and medium grits.

Sanding Accessories

Sanding discs in fine, medium and coarse grades are made to fit mandrel No. 402. They can be used for nearly any small sanding job you might have, from model making to fine furniture finishing. In addition, there is the drum sander, a tiny drum which fits into the Rotary Tool and makes it possible to shape wood, smooth fiberglass, sand inside curves and other diffi- cult places, and other sanding jobs. You replace the sanding bands on the drum as they become worn and lose their grit. Bands come in fine and coarse grades.

Wire Brushes

Three different shapes of wire brushes are available.

For best results wire brushes should be used at speeds not greater than 15,000 RPM. The three shapes come in three different materials: stainless steel, brass and carbon wire. The stainless steel per- form well on pewter, aluminum, stainless steel, and other metals, without leaving "after-rust". Brass brush- es are non sparking, and softer than steel; making them good for use on soft metal like gold, cooper and brass. The carbon wire brushes are good for general purpose cleaning.
