How to Get the Most Out of Deburring Tools

Deburring is an essential part of the metal and steel fabrication process. You need the correct tools to smooth out any rough edges or ridges produced during the manufacturing process in metal fabrication to ensure the part is properly prepped to improve its functionality and that it is safe to handle.

As well as deburring, edge breaking and chamfering also form part of the process for finishing machined parts. Edge breaking removes sharp edges and corners to make the component tactile and safe to use. If the component will be painted, it helps the paint stick to the area and have a more consistent paint thickness. Whereas chamfering involves removing the sharp corner to a required angle and this is normally specified within engineering drawings.

DeburringTypes of Burrs

There are various factors to consider when choosing what deburring method meets your requirements:

  • Work material
  • How tall and thick the burr is
  • The edge radius
  • Stock loss and surface finish
  • Required finish

You’re likely to get light burrs from using a cutting disc on thinner steel, whereas medium burrs will likely occur from using a laser or guillotine on the component where you’ll get a slight curve on the edge. If you use a grinding disc or a more aggressive method, such as plasma cutting, you’ll find heavy burrs left on the component.

A good deburring tool is essential to any workman’s toolbox and will save you time and money in the long run. Deburring tools can be used on plastic, nylon, copper, wood, mild steel, mild cast iron and aluminium. 

A traditional deburring tool is good for small areas with light burrs on softer materials, however, if you’re working on a larger scale with heavy burrs and harder materials then our Norton tools used with a right angle grinder, or other power tools, will be more efficient and quicker.

The Norton range for deburring will quickly and easily achieve radius bevelling on metal projects and will also remove surface defects whilst resisting clogging on soft materials. You can choose from a range of grades to cater for lighter to heavier deburring.


Using a Right Angle Grinder (RAG)

The RAG is the most versatile machine and a staple of any workshop. It is a key tool for the deburring process. It can replace numerous tools and make the most tedious, labour intensive jobs quicker and easier.

It’s important to choose the correct disc to use with your RAG when deburring different materials.


Stainless Steel

The thicker the sheet of stainless steel, the larger the burr as the process of cutting this will be more aggressive. To remove heavy burrs on stainless steel, we would recommend the Quantum3 Inox grinding disc. The self-sharpening ceramic grain technology is ideal for high material removal in less time. The longer wheel life means less downtime and waste, so fewer wheels are needed. As an added bonus, it’s also more comfortable to use and reduces hand fatigue. ORDER NOW

For medium burrs, we would recommend the Vortex Rapid Blend non-woven disc with a tight, unitised construction which resists loading when deburring. ORDER NOW

For light burrs, use NEX-2SF discs slowly across the workpiece using just the weight of the angle grinder for pressure. ORDER NOW


Carbon Steel

DeburringFor heavy burrs on thicker carbon steel, grinding wheels, such as Omega, is ideal for heavy industrial use on most hard steel types and alloys. ORDER NOW

For medium burrs on carbon steel, use medium grade flap disc, such as Norton Quantum R996 in 60 grit. Flap discs cut faster and provide a better finish than fibre discs with the added benefit of longer life thanks to the flap construction. ORDER NOW

When deburring light burrs on carbon steel, try Vortex Rapid Prep flap discs which is ideal for difficult corners and edges. ORDER NOW


Aluminium and Non-ferrous Materials

For heavy burrs on aluminium and non-ferrous materials, F100 fibre discs are ideal for a coarse surface finish and low stock removal. ORDER NOW

When deburring medium burrs on aluminium and non-ferrous metals, the Blaze Rapid Strip non-woven discs leave a thoroughly cleaned surface that ensures excellent adhesion for subsequent processes, such as coating. ORDER NOW

For light deburring on aluminium, Beartex High Strength discs are ideal for following contours and awkward profiles easily due to the high strength nylon. Its open structure prevents loading when deburring and is tough enough to resist tearing on burrs and sharp edges. ORDER NOW

Alternatively, wire brushes are suitable on flat areas on soft materials as they do not load – ORDER NOW


Using Die-Grinders

Instead of using a RAG, a handheld Die Grinder is an alternative tool which can be used with flap wheels and carbide burrs for deburring in hard to reach areas or smaller components which the RAG is either too powerful or too large to access. Their versatility makes them ideal for all types of fabricators, from welders to sheet metal workers, especially when precision is needed. 


Stainless Steel and Carbon Steel

Spindle mounted flap wheels, such as Norton Quantum, are ideal when used with a die grinder for deburring on stainless steel and carbon steel. They can conform to intricate shapes and contours and are easy to operate as they do not require adjustments, dressing or preparation before or during the operation. Norton flap wheels are more forgiving than other abrasives, reducing the risk of flattening, gouging or surface deformation, meaning fewer rejected parts and better long term productivity.  ORDER NOW

For heavy burrs on stainless steel and carbon steel, use mounted points or carbide burrs, such as Inox cut style, on a die-grinder. ORDER NOW

Start the burr off slow with only a little pressure and increase the pressure as you go, as the speed will differ depending on the pressure you apply.


Aluminium and Non-Ferrous Materials

X-Treme S R427 spindle mounted flap wheel uses hard silicon carbide grain and is ideal for weld removal on copper, titanium, bronze, brass, non-ferrous materials, stone, glass and plastic. ORDER NOW

The aluminium special style carbide burr is suitable for deburring of aluminium alloys and plastic wide tooth formation. ORDER NOW
