For promoting safety, the industrial brush distributors put every effort to inform their buyers of the potential hazards as well as their responsibilities for proper and safe operation of the power brushes. Failing to understand those safety requirements would mean severe injury.
So, here are some power brush safety tips from Hight Brush, an industrial brush distributor in Texas. Follow them:
Before you start using an industrial brush, inspect it for damage, rust, speed limit etc. If no-load speed marked on the tool is higher than the speed limit, don’t mount the power tool. Carefully inspect and jog the machines to assure the tool is mounted in a proper and secure way, that machine guards are in their place and that there isn’t any vibration etc. Run your machine at an operating speed for a minute before applying the work-don’t stand in-line or in front with the brush.
Wear full face shields over the safety goggles with the side shields. These should be worn by the operators and all others who are in the area of the power brush operations. Keep the machine guards in their respective places. Observe all the speed restrictions that are indicated on the labels, containers, brushes or printed in the pertinent literature. Make sure to comply with safety standards of the Industrial Division of the American Brush Manufacturers’ Association and ANSI. Wear appropriate equipments like protective clothing, a respirator, gloves, etc. before dealing with the power brushes. Injury can be prevented by using these protecting clothing and accessories.
Don’t use too much of pressure when using a power brush. Too much of pressure causes over-bending of filaments as well as heat build-up, resulting in rapid dulling, filament breakage and reduced brush life. Rather than using too much pressure on the brush, it’s suggested that you use a brush that has a more aggressive cutting action, the one which has a higher speed or a different brush variety. Make sure the max. operating speed marked on wire brush is as high as ‘no load’ speed that’s shown on the name plate of the brush.
Don’t allow unsafe conditions to prevail. Most of the time because of worn bearings, bent spindle, an operator abuse, an unusual application or an improper use, a brush can fail. Don’t use or continue using the failed brush or the one that’s functioning inappropriately because this increases the probability for more brush failure as well as the hazard of injury. Cause of failure, however must be assessed and corrected.
Store the power brushes in a dry, clean container. Don’t allow distortion of the brush components/filaments or the foreign matter to become lodged in the face of the brush.
Hight Brush is a reputed wire wheel brush supplier. So, we have made sure to mention one more safety tip that must be followed while using wire wheel brushes. The direction of rotation must be periodically reversed for taking advantage of the self-sharpening action, which will result. This can be done by removing the brush from spindle and turning it side-for-side and remounting in a secure way.
It is very important that you understand these safety requirements. If you fail to understand them, an injury may be the result. So, be very careful when using the industrial power brushes for your need.

Wire brushes are available in two varieties-crimped wire brushes where each stand wire has bends or crimps in it and the straight wire brushes where the wire is used as is. Two unique styles are involved here. The crimped ones are made in the solid wheel kinds, while the straight ones are in knots or twists. The reason for these differences is the manufacturing method. Both of the styles are wires bent like the hair pins. When wires in crimped brushes are doubled back, crimps interlock and are protected inside face plates. But straight wire brushes won’t interlock. So, to lock the wire in face plates, wires should be twisted as well as knotted in individual clumps.
Straight wire brushes are mostly used in gear deburring for its aggressive nature. The reason these brushes are more aggressive is that being straight all the wire points are on O.D. where they fit in. Crimped wire brushes, have areas around the periphery, which are dull because the bends of wire are uncovered. This cuts down significantly on amount of the work done. Hardness of wire approaches hardened tool steel so that most of the gear materials may be edge-broken or deburred with wire brushes. These brushes are basically used where finish isn’t critical, where time cycles should be short and where burrs are quite heavy.
The wire brushes generally work by lifting burrs and bending them back against parent metal of gear. They then attack burr at this point and wears them away. They should be aggressive on all the edges but must do very little work on solid areas of gear. This is the reason why brushes work well on the automated equipments like robots. The spur brushes are perfect candidates for the wire brush treatments because heavy burrs are quickly remove and edge break is produced around tooth profile. Brushing has minimized gear failures by ninety percent in a few heavy duty transmissions.
The helical gears pose a problem for the wire brushes if gears aren’t shaved. The brushes roll some parent gear material into tooth on acute side only. Obtuse side is not a problem. Thus all focus must be directed to acute side. If gears are hobbed first, then brushed to produce a huge break and then shaved for precision needed, rollover goes. Since there is a break already on edge, it would be burr-free when finished.
The wire brushes are even manufactured with stainless steel wire in both straight and crimped styles. The stainless wire tools must be used where contamination is the problem. A stainless wire isn’t as hard as carbon wire, thus it doesn’t cut even. Stainless wire work gets hard quickly thus it doesn’t have the life of the carbon wire. Since its initial cost is high and life is less, the stainless brushes must be used only when needed.
In this epoch of robots, high tech, machining cells, automatic machines etc. do you think there is a niche for the power brushes? Let Hightbrush answer this question. But before answering, we shall ask you a few more questions. Are you all ready to answer them? If yes, let’s start with it!
- What tool do you think the gear manufacturer has in his arsenal which allows him to deburr the hardened gears, green gears, ground gears, shaved gears and hobbed gears?
- What is the tool that allows the finishing of pump gear journal without changing size or concentricity?
- What is the most adaptable tool that can be used on bench motors, power tools, fully and semi automatic machines and robots?
The answer to all the above questions is power brush. However, this doesn’t mean that power brushes are an answer to every deburring or finishing problem. They are just a potential solution, which must be considered when these kinds of problems arise.
Power brushes shall fit in with most of the production and budget requirements. Mostly, cycles for gear deburring with power brushes are in fact measured in seconds. The costs of equipment begin under 1000 USD and systems may be upgraded as much as the budget allows. The tool is basically a throw-away product which means no reworking or regrinding. For most of the applications, even if there are angles, concave or convex forms, this brush will conform and wear into shape or form so that no pre-dressing is needed. A power brush also stress-relieves a gear because it can break and round all the sharp edges as well as fillets, thereby reducing the gear tooth breakage.
Power brushes sometimes are used for removing burrs and breaking edges but they are done only for the purpose of assembly. The brushing before assembly makes gears easier for handling and part by part is improved. It can help in solving different kinds of assembly problems.

Power brushes are used by industrial professionals for polishing, edge blending and removing contamination from the surfaces. They are available in various shapes, sizes and brush filament fabrications. Common types of power brushes include end, tube, cup and wheel configurations.
End brushes are perfect for industrial cleaning uses where space restriction is an issue. The wire end brushes are typically used for dies, polishing molds, cleaning castings, flash removal, brushing internal surfaces of the holes and preparing surfaces for welding purpose. They are available in knotted and crimped configurations.
Tube cleaning brushes are used mainly for deburring purpose and are characterized by spiral or twisted bristles. They are also popular as bottle or flue brushes. These brushes are generally suitable for cleaning boiler tubes, air conditioning condensers as well as the inside part of tubular holes and cylinders. These tools are usually available in a single-stem single spiral construction for manual use or in a double stem double spiral/single spiral for powered application. Single stem tube cleaning brushes come up with long wire handles and a loop at the end, whereas the double stem ones have a heavier construction with denser brush face for aggressive brushing. The materials, which are used for brush filaments include brass, steel and nylon.
These industrial tools are used in removing rust, paint and scale. They are also used for polishing and deburring purpose. Different fill materials and duty levels are available in cup brushes for suiting different kinds of tasks like surface preparation, finishing operation and removing burr.
Wheel brushes offer straight line brushing action for cleaning, polishing, deburring, weld blending, surface finishing, and removing rust, paint, scale and other kinds of contamination. They are suitable for applications with different kinds of bench grinders, hand-held grinders, robotic finishing tool or for mounting onto a driven arbor in the production method. Hight Brush, the industrial brush supplier, stocks a wide range of wheel brushes, which range from big wide face brushes to small diameter copper center wheel brushes. The different styles of these tools available are either filled with synthetic or natural fibers or with crimped wire. The twisted knot wheels, however, are filled up with straight wire, which are twisted to different specifications.
