About Finishing

No-Mess Polishing Bobs for
Aluminum, Soft Metals, and Nonmetals

The silicon carbide abrasive cuts quickly with light pressure.

Buffing and Polishing Compounds

Apply a layer of compound by holding one of these bars against a revolving buffing wheel.

Aggressive Buffing and Polishing Compounds

Remove more material than traditional buffing compounds. These consist of abrasive grains embedded in glue to adhere to your buffing wheel. They leave a dull satin finish. Also known as greaseless compounds.

Smoothing and Polishing Stones
for Aluminum and Soft Metals

The abrasive is specially treated for use on aluminum, brass, bronze, and other soft metal molds and dies.

Diamond Lapping Paste

Diamond cuts more quickly, lasts longer, and leaves a finer finish than other lapping compounds.

Diamond Lapping Paste Assortments

Choose between a set of six water-soluble pastes or a set of six oil-soluble pastes.

Diamond Lapping Slurries

Thinner than paste for easier, even spreading over flat surfaces.

Lapping Paste for Aluminum and Soft Metals

The abrasive won’t embed in soft metals, preventing scratches and material buildup on your work surface.

Lapping Film for Aluminum and Soft Metals

This film abrades quickly and prevents material buildup.

Diamond Lapping Film

Diamond cuts more quickly, lasts longer, and leaves a finer finish than other lapping grains.

Timesaving Lapping Grains
for Aluminum and Soft Metals

The grains break down during use so they function first as an abrasive and then as a polish.

Diamond Lapping Grains

Diamond cuts more quickly, lasts longer, and leaves a finer finish than other lapping grains.

Fine-Polishing Media for
Aluminum, Brass, and Soft Metals

Often used as the final step after other media to create an extremely shiny finish.

Light-Cleaning-and-Polishing Media
for Aluminum, Brass, and Soft Metals

Remove tarnish, oxidation, and light scratches from parts with fine detail or engraving.

Deburring and Edge-Rounding Media
for Aluminum, Brass, and Soft Metals

Good for light material removal.

Flexible Cylinder Hones for Aluminum and Soft Metals

The aluminum oxide abrasive, which has blunt edges, won't clog the hone, especially when used with honing oil.

Flexible Precision-Finish Cylinder Hones

The flexible shank on these hones gives you access to hard-to-reach spots. A knurled adjustment knob lets you adjust the pressure applied to the side of the cylinder to achieve your desired finish.

Precision-Finish Cylinder Hones

Precisely size the hone to your cylinder in micrometer increments.

Sanding Sticks for Aluminum,
Soft Metals, and Nonmetals

The rubber backing cushions the abrasive to prevent gouging your aluminum, soft metal, and nonmetal work surfaces.

Scale Removers for Chillers and Boilers

Remove scale from water-cooled condensers, chillers, and non-potable water boilers.

Boiler Cleaner/Conditioners

In addition to cleaning steam and hot water boilers, these conditioners control foam and pH levels to improve boiler efficiency and reduce energy costs.

Scale Removers for Drinking Water Chillers and Boilers

Dissolve scale and mineral buildup in drinking water systems with these scale removers. They meet NSF/ANSI Standard 60 for use with components that come into contact with drinking water.
