Features
100% Brand new and high quality.
Great for cleaning and general surface-finishing many items made from gold, bronze, copper or brass.
Brass brushes are non-sparking and softer than steel. They will not scratch soft metals like gold, copper, brass.
Use a brass brush to create a soft, satin or matte finish.
Very effective on flat surfaces and in hard-to-reach areas like slots (Brass wire is non-sparking and softer than steel)

User Tips
For best results, insert the accessory bit all the way into the tool and then back it out slightly before tightening down. This provides plenty of shank for the collet or chuck to hold onto the bit.
Keep a light touch, letting the tips of the brush do the work. Too much pressure can break the bristles.
Before using on a material, allow the tool with brush to run at operating speed for at least one minute to discharge any loose bristles. Make sure no one stands in front of or in line with the brush.
The bristle brush can be used with polishing compound.
Do not run in excess of 15,000 rpm. Therefore, do not use with a Single-Speed MultiPro Rotary Tool or a Heavy-Duty Flex-Shaft Tool unless you use a Speed Control.
Always read and follow all safety instructions of your rotary tool and always wear eye protection.
Great for contractors
