End Brushes

End brushes are suitable for industrial cleaning applications where restricted space is an issue. Typical wire end brush applications include: polishing molds or dies, cleaning castings, brushing the internal surfaces of holes, flash removal, spot facing, and surface preparation for welding. Typical use involves a hand-held high speed air tool, electric drill, drill press, or robotic finishing equipment.

End brushes are available in the following sizes and formats:

Solid Fill Wire End Brushes

Solid Fill Wire End Brushes are available in crimped carbon steel, stainless steel, brass, or bronze wire . Synthetic and Natural Fiber Options include: Abrasive Nylon, Nylon 6-6, Tampico, Polyester, Polypropylene and Horsehair. Wire size ranges from .003" to .020". Abrasive Nylon ranges from 500 Grit (fine) to 46 Grit (coarse). Other synthetic materials are generally available in .005" through .020" for end brush applications. End brush diameters include 3/8", ½". ¾", and 1" brush part. Standard shank dimensions are ¼" wide by 7/8" long. Standard trim length for Solid Fill End brushes is 1". Adding bridles to an end-brush reduces the tendency to flare-out during operation and concentrates the wire points on the work surface directly in front of the brush. Bridles may be removed as the brush wears. The end brush cup may also be coated with a plastic material to reduce damage from contact with the work piece.

Knot Style End brushes

Knot Style End brushes are suitable for severe cleaning applications such as removal of heavy scale, corrosion, weld spatter, and rust. Available in .014" and .020" carbon steel and stainless steel in ¾" and 1 1/8" cups, and with optional bridles to control brush face. Standard shank dimensions are ¼" wide by 7/8" long. Standard trim length for Knot Style End brushes is 7/8" to 1-1/8".

Flared Wire End brush

Flared Wire End brush provides side cleaning action, and will not score blind hole bottoms. Flared end brushes are available in a variety of diameters measured across the flared brush part: 1", 1 ¼", 1 ½", 2", 2 ¾", 3", and 4". Flared End brushes can be filled with steel wire, stainless steel wire, or brass wire in sizes from 0.005" to 0.020". Standard shank dimensions are ¼" wide by 7/8" long.

Hollow Center End brushes

Hollow Center End brushes are designed to clean around protruding objects. The hole in the center also prevents balling up of the wires in the center of the brush. Hollow center end brushes are available in ¾" and 1" diameter, and can be filled with steel, stainless steel, and brass wires in a range from 0.006" through 0.020". Standard shank dimensions are ¼" wide by 7/8" long. Standard trim length for Hollow Center End brushes is 1".

Pilot Bonding Brushes

Pilot Bonding Brushes are specially designed to clean around rivet or bolt holes. Brush diameter is ½"; Trim length is 3/8"; Brush is filled with .004" Stainless Steel wire. Only the pilot size varies, from 3/32" up to ¼".

Spot Facer Drill brushes:

Spot Facer Drill brushes provide two functions at the same time: cleaning the area around a bolt hole, and drilling or reaming the hole itself. Or, turn the drill around and use the solid end as a pilot to guide the cleaning around a hole for a bolt, screw or rivet. Brush sizes include ½", ¾" and 1 1/8" diameter to fit a variety of drill or tap sizes (drill or tap not included). Set screw secures drill or tap in place. Wire fill material options include steel or stainless steel in diameters from 0.004" to 0.020". Other wire sizes and larger format brushes are available as special order items.

Encapsulated End brushes

Encapsulated End brushes offer greater control over the brush wires and increase effective stiffness of the brush by shortening the free wire. Wires are encapsulated in a synthetic elastomer in either normal or hard durometers. Three Solid Fill diameters are available: ½", ¾" and 1" brush part. Carbon steel and stainless steel wire fill materials from 0.006" to 0.020" are available.

Side Bottom

Side Bottom brushes the side and the bottom in one operation. The brush has right angle junctures. The brush shank is ¼" diameter. Overall length varies from 3 ¼" to 4 7/8" with the diameter of the square brush part from 1" to 3". Wire diameters of .006" and .010" are standard in Steel, Stainless Steel and Brass. Special round and square sizes are available in most wire and filament sizes.
