Metal parts fresh off the production line often have burrs, sharp edges, scales, rust or other defects that need to be removed before the part is ready for use. Deburring and finishing metal parts is an important manufacturing process that ensures quality end products with smooth, clean finishes. An innovative tool that makes deburring incredibly easy and efficient is Mr Deburr.




Deburring is the process of removing the excess material or defects left over from manufacturing processes like machining, stamping, or laser cutting. These burrs and sharp edges are undesirable for a few key reasons:


- They pose a safety hazard for workers handling the parts. Sharp burrs can cause cuts and injury.

- Burrs affect proper assembly and function. Smooth surfaces are required for mating and moving parts.

- They negatively impact appearance. Visible burrs make a part look unfinished.

- Burrs reduce fatigue strength. They act as stress concentrators and can lead to early failure.


Traditionally, deburring was an extremely labor intensive manual process done by hand with files or abrasives. It was time consuming, injury prone, and inconsistent in result. Mr. Deburr revolutionizes the deburring process by making it fast, easy, safe and consistent.


Mr. Deburr is a cylindrical deburring tool with a abrasive-coated flexible shaft. It attaches to any drill for high speed rotational deburring. The flexible shaft easily reaches into cavities and complex geometry. It conforms to surfaces and provides controlled, precision deburring action without damaging the part surface. Thousands of microscopic abrasive particles continuously fracture off during use, exposing fresh sharp grit to maintain optimal cutting ability.


Some key benefits of using Mr. Deburr:


Speed - Deburring time is decreased by 90% 

Simplicity - No training required, just attach to a drill and deburr

Safety - Reduces hand injuries from manual deburring

Consistency - Gives uniform results for every part 

Lower Cost - Reduces labor time and tooling costs

Multi-Purpose - Performs well on all metals - steel, aluminum, titanium, etc


Mr. Deburr saves manufacturers time and money while improving quality. It is effective on CNC machined parts, forged parts, castings, sheet metal parts, extruded parts, welded fabrications, and more.


Let's take a closer look at how this innovative deburring tool works and what makes it so useful for metalwork applications.


How Mr. Deburr Works 


Mr. Deburr consists of a flexible steel cable coated in microscopic abrasive particles. The shaft is encased in a plastic clamshell with a shank that fits into any standard drill chuck. As the shaft spins at high speeds, the grit particles fracture to expose fresh sharp edges that cut into the surface defects. The flexible cable easily accesses hard to reach areas and conforms to curved surfaces.


The shaft continuously releases spent abrasive to expose new cutting grit, so it maintains optimal deburring ability throughout its life. The grit size and shaft thickness can be selected based on the material being deburred. The one-piece construction ensures the grit stays evenly distributed along the entire length rather than collecting more heavily at one end.


Mr. Deburr is designed for wet deburring. Either water soluble oil or soapy water lubricant is required when using it. The lubricant flushes away the micro-particles eroded during deburring and keeps the shaft cool. The wet operation contains the metal particles and improves the surface finish.


The simple and intuitive design allows any worker to start deburring immediately with perfect results. There are no expensive power supplies or extensive training required. Just chuck it into a drill and begin lightly brushing the surface defects away.


Thousands of shops have adopted this innovative approach to deburring and finishing metals. The benefits are clearly realized in time savings, lower labor cost, and high quality finished parts.


Applications and Use Cases


Mr. Deburr excels at removing defects from all types of machined metal components across many industries including:


CNC Machined Parts


Computer numerical control (CNC) machining produces burrs and sharp edges along the machined features. Mr. Deburr can rapidly deburr the entire part after machining, regardless of complexity. For high production runs, it is easily automated in a robotic work cell.


Stamped/Punched Parts 


The shearing action of stamping and punching leaves significant burring and rollover along the edges. These must be cleared prior to plating or powder coating. Mr. Deburr makes quick work of removing the defects.




The rough surfaces and runner lines of castings are smoothed and finished with Mr. Deburr's flexible abrasive shaft. Grinding or filing by hand is eliminated.


Additive Manufactured Parts


AM processes like 3D printing leave behind a rough layered surface profile and loose metal particles. Mr. Deburr provides an efficient way to finish these complex geometries.


Welded Fabrications


Spatter, slag inclusions, and uneven weld toes are common defects when welding metal fabrications. Mr. Deburr is ideal for removing these weld imperfections.


Plastic Parts


The benefits of Mr. Deburr extend beyond metal finishing. It can also deburr and finish hard plastics like nylon, acrylic, polycarbonate, and fiber reinforced plastics.


And Many More...


In addition to the above examples, Mr. Deburr delivers superior deburring results on extruded profiles, molded parts, tubing, stamped contacts, turned parts, and any other manufactured metal components. It saves time and frustration versus manual methods.

2. Attach shaft to drill - Chuck the shaft end into any standard drill, variable speed preferred. Light tension only.


3. Wet the shaft tip - Dip in water soluble oil or soapy water. Re-wet frequently.


4. Deburr part features - Lightly brush the spinning shaft over the burrs and defects to remove.


5. Maintain steady axis angle - Work perpendicular to features for maximum cutting action.


6. Let the tool do the work - Use light pressure and high RPM for optimal results.


7. Refurbish shaft as needed - Grit will eventually wear down.


Following these basic guidelines, any shop can quickly master deburring with Mr. Deburr.
