Description

Our Standard Abrasives™ MD Mini-Brush features medium density (MD) Buff and Blend material for efficient restoration of original, high-quality finishes on fabricated steel parts. While welds or other imperfections might detract from a fine finish, the original luster can still be salvaged – even revitalized and renewed – with the help of this abrasive brush.

Restoring Original Finishes
Conventional methods for blending weld traces and other imperfections can be time consuming and unpredictable. The Standard Abrasives™ MD Mini Brush restores the original appearance of metal parts quickly and easily. Users begin by welding and setting the grain as normal. Then, the Standard Abrasives™ MD Mini Brush follows to deliver stainless finishes.

The brush is constructed by attaching thin flaps of abrasive material mounted to a fiberglass core. Its design utilizes the ˝face˝ of the material rather than the ˝edge.˝ resulting in fine finishes without leaving the traces of lines associated with ganged arbor hole discs. The flaps are buoyant and responsive, so, rotating on the workpiece they splay out subtly and cover more surface area to eliminate gaps. The brush easily attaches to a die grinder or rotary tool and can be brought to the workpiece if necessary.

Medium Density Material Produces Fine Finishes
Our MD Mini Brush utilizes our Standard Abrasives™ Buff and Blend medium density non woven material. Among Buff and Blend products, the Mini Brush is the least aggressive, making it ideal for producing fine finishes on irregular shaped parts.

Benefits of Open Web Abrasives
The Standard Abrasives™ MD Mini Brush is constructed with aluminum oxide mineral and nonwoven nylon fibers bonded with resin, resulting in a dense open web. Resin bonds tolerate heat and help enhance overall durability of the abrasive. Aluminum oxide mineral cuts sharp and is friable, fragmenting under heat and pressure to reveal sharp cutting edges, offering a consistent cut throughout the life of the abrasive.

Gaps between the nonwoven nylon fibers allow swarf and debris to escape, so the abrasive does not get clogged with buildup and keeps cutting sharper for longer. Moreover, the nylon fibers are buoyant and responsive, so you get a consistent cut without gouging or marring the workpiece. Given that maintaining part geometry – especially on fabricated steel parts – is often a top concern, the mini brush’s ability to conform to the substrate without compromising part geometry is one of its key benefits. It helps reduce the likelihood of having to discard scrap parts due to incorrect tolerances, as well as minimizes the need for rework.

Broad Range of Grades
The Mini Brush is color coded by grade to help users quickly identify the right grade for their application. Available grades range from very fine to extra coarse to meet the needs of many different surfaces. Medium and fine grades will cut less aggressively but leave a finer scratch pattern, whereas coarse grades will cut more aggressively and leave a rougher scratch pattern.

Altogether, the Mini Brushes provide a quality, fast and easy solution for restoring original steel finishes.

The product I ordered was back ordered. Gustavo Martinez contacted me personally to help me get what I needed. He called multiple suppliers to see if he could get the product in pieces instead. In the end her helped me figure out that I didnt even order the correct product for my application and got the correct one ordered for me. By far the best customer service I have ever had from an online order!

We were able to find what we needed at a reasonable price. Checkout was relatively easy as well. After ordering, we got a notification that the items we ordered were on backorder. It would've been nice to have that inventory be accurate on the website before placing the order, but I understand things happen. We were given the option to cancel, but since we needed those particular items in no huge rush, decided to keep it in place. We received one shipment of the ear protection, but I believe the remaining maintenance kits are still on backorder. I hope we receive them soon. Other than the discrepancy in inventory and the wait for the two shipments, things went well. When we need more PPE, we'll likely shop with them again.

Reply from www.envirosafetyproducts.com

Thank you for your feedback. We’re sorry for the frustration this caused. We want to clarify that your order was for one child-size cervical collar, which is what was shipped. The product photo shows both the adult and child models so customers can see the size differences, but each is sold separately.

Our team reached out by phone and email to explain this and offer you the adult size free of charge, but we regret that it left you feeling dissatisfied. If you’d like to discuss further, our management team would be happy to assist. Please contact us at: (800) 637-6606

The website said 1 day when ordering, the reason we purchased from you. It's been 14 days and we still don't have it. The other issue is you were not the lowest priced. I called customer service and they answered my questions but did not seem concerned at all. Actually I remember hearing a snicker or light laugh.
