A burr is found on the entrance and exit of a drilled hole and the degree and size of the burr is dependent on the material and sharpness of the drill. Deburring holes is usually a costly and time-consuming operation, with the back sides of holes being particularly difficult as they are frequently inaccessible with conventional 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.
Types of Deburring Tools
There are various factors to consider when choosing what deburring method meets your requirements:
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.
An angle grinder, also known as a side grinder or disc grinder, is a handheld power tool used for grinding (abrasive cutting) and polishing. Although developed originally as tools for rigid abrasive discs, the availability of an interchangeable power source has encouraged their use with a wide variety of cutters and attachments.
Angle grinders can be powered by an electric motor or compressed air. The motor drives a geared head at a right-angle on which is mounted an abrasive disc or a thinner cut-off disc, either of which can be replaced when worn. Angle grinders typically have an adjustable guard and a side-handle for two-handed operation. Certain angle grinders, depending on their speed range, can be used as sanders, employing a sanding disc with a backing pad or disc. The backing system is typically made of hard plastic, phenolic resin, or medium-hard rubber depending on the amount of flexibility desired.
Angle grinders are standard equipment in metal fabrication shops and on construction sites. They are also common in machine shops, along with die grinders and bench grinders.
Carbide Rotary Burrs, often referred to as rotary files or die grinder bits are used for cutting, shaping, and grinding, and for the removal of sharp edges, burrs and excess material (deburring).
For drilling holes in hard metals you would need to use carbide micro drills or carbide straight shank drills. For cutting slots, routing, profiling, contouring, counter-boring, and reaming you would use a a carbide end mill, carbide slot drill or a carbide router. For cutting and shaping stone or glass you would use a Diamond Burr.
Hand deburring tools
If there’s a tool that is never left out of any machinist’s toolbox, it’s a hand deburring tool, also referred to as a burr whip. The blades of the tool come in different sizes, materials, and shapes. They also work well on flat surfaces and internal curves but are not optimal for external round surfaces.

How is deburring done?
Deburring is a secondary operation of a machining process that enhances the final quality of the product by removing raised edges and unwanted pieces of material, known as burrs, left by the initial machining processes. Burrs are created from shearing, bending, cutting, piercing, and compressing materials.
Why is deburring necessary?
When being cut, metals leave very sharp, rigid edges. Deburring eliminates ease sharp edges so that the worker can handle it without the possibility of getting cut or injured because of it. Additionally, a deburring machine also helps to maintain the safety of other important machines.
What are deburring blades used for?
Deburring tools are used to remove excess material from the edges or surface of a raw, unfinished product and are relatively straightforward to use. Simply slide the blade at an angle along the edge to create friction and scrape away the burrs, leaving a smooth and even finish.
