What are End-Brushes & Their Types

End brushes are an excellent solution for industrial applications where power brush cannot be used due to space issues. End brushes are generally used with a high-speed hand-held tool for applications, including cleaning, polishing, deburring, and surface preparation.

What are End Brushes?

End Brushes are considered an appropriate choice for precision treatment and for areas that are difficult to access, as these tools run in small sizes. They're used for deburring materials and tools. Compatible materials include rubber and plastic variations. Aesthetically, the filaments are bundled into the cup, and therefore the filler generally spans outward to contact hard to succeed in areas when the corresponding machine is operational. End brushes are typically available in crimped and knotted configurations.

Difference Between Knotted & Crimped End Brushes

The two most used wire abrasive end brushes category for drills and dies grinders are crimped or knotted, respectively. Here is the comparison between both the categories:

Crimped End Brush

    Crimped end brushes hold a wavy or crimped metal construction that makes a firm yet flexible application. They will tackle most equivalent tasks as knot end brushes but are suitable as a less aggressive abrasive with more flexibility within the wires.

    Knotted End Brush

      A knotted end brush features a sturdier construction that permits for more aggressive action than crimped brushes. For making such types of brushes, groups of metal wire filaments are twisted together to make multiple cable twist knots. Knotted End Wire Brush creates a more rigid wire construction that extends the wires' lifetime and may be used for more heavy-duty abrasive applications with faster removal rates.

      Applications of End Brushes

      Following are the leading industrial uses of Twisted Wire End Brushes.

      • Cleaning of Carbon
      • I.D. pipe cleaning
      • Mold and die cleaning
      • Removing weld slag
      • Surface preparation for welding
      • Polishing tools
      • Rubber and plastic flash removal
      • Paint, rust, and corrosion removal
      • Smoothing rough edges
      • Deburring slots
      • Cleaning pipes and recessed areas
      • CNC equipment maintenance and cleaning

      Types of Metal End Brushes 

      End brushes are capable of performing on a spread of metal surfaces. We provide our Wire brushes in steel, chrome steel, and tempered steel.

      • Carbon steel may be a commonly used general-purpose brush made with the softest metals, which makes it more suitable for ferrous metals like iron, steel, and forged iron. 
      • Stainless steel brush can perform two jobs: cutting and polishing harder surfaces and non-ferrous metals like aluminum, copper, and brass.
      • Tempered steel is the toughest of the end brushes and is supposed for more aggressive cleaning and cutting.
      • Solid fill end brushes are available in crimped steel, chrome steel, brass, or bronze wire. Synthetic and natural fiber Options include: Abrasive Nylon, Nylon 6-6, Tampico, Polyester, Polypropylene, and Horsehair.
      • Knot Style End brushes are suitable for severe cleaning applications like removing heavy scale, corrosion, weld spatter, and rust. Available in .014″ and .020″ steel and chrome steel in ¾" and one 1/8″ cups, and with optional bridles to regulate brush face.
      • Flared Wire End brush provides side cleaning action and can not score blind hole bottoms. Flared end brushes are available during a sort of diameters measured across the extended brush part: 1″, 1 ¼", 1 ½", 2″, 2 ¾", 3″, and 4″. Flared End brushes are often crammed with steel wire, chrome steel wire, or brass wire.
      • Hollow Center End brushes are designed to wash around protruding objects. The opening within the center also prevents balling from the wires within the center of the comb.
      • Pilot Bonding Brushes are specially designed to wash around rivet or bolt holes. Brush diameter is ½"; Trim length is 3/8″; Brush is crammed with .004″ chrome steel wire. Only the pilot size varies, from 3/32″ up to ¼".
      • Spot Facer Drill brushes provide two functions at an equivalent time: cleaning the world around a bolt hole and drilling or reaming the opening itself and turning the drill around to use the definite 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 suit a spread of drill or tap sizes (drill or tap not included). The set screw secures drill or tap in situ. Wire fill material options include steel or chrome steel in diameters from 0.004″ to 0.020″. Other wire sizes and bigger format brushes are available as special order items.
      • Encapsulated End brushes offer greater control over the comb wires and increase the comb's sufficient stiffness by shortening the free wire. Wires are encapsulated during a synthetic elastomer in either standard or hard durometers.
