The Various Shapes of Carbide Burrs and How To Use Themĭeciding on what shape to use will depend on the profile or cut you are looking to achieve. Typically carbide cutters come in standard diameter head sizes such as these:ģ. Long shank carbide burrs can also be found, and these are great for detailed carving in hard-to-reach areas of your work. a 1/4 inch shank (") or a 6 millimetre shank (mm) These are usually found in the following shank sizes: These will be labelled in inches or millimetres, i.e. The shank is the mount or spindle of your burr that fits into your rotary tool, die grinder, CNC machines, micro motor etc so to make it clear, it is the opposite end to the working part of the tool. Shank diameter sizes of your carbide burrs: There is also a cutter known as a left-hand cut carbide burr which you would use if you needed to reverse the rotation of the burr due to a double angle for instance. The below image indicates the double cut, single cut and again, the double cut or diamond cut. Similar to double cut are Diamond Cut carbide burrs which have multiple cutting faces, often found on router end mills. These are the most popular cut and will see you through most applications.ĭouble-cut burrs for use on non-ferrous materials and plastics tend to have wide chip space and are often referred to as Aluminum cut. So this will give you a medium-light stock removal. They have more cutting edges and will remove material faster, leaving a smoother finish than a single cut due to producing smaller chips as they cut away the material. Use for heavy stock removal, milling, deburring and cleaning.ĭouble cut (2 flutes cut across each other) carbide burrs tend to be used on ferrous and non-ferrous metals, aluminium, soft steel and also for all non-metal materials such as plastics and hard wood. These tend to be used with stainless steel, hardened steel, copper, cast iron, and ferrous metals and will remove material quickly. Single cut(one flute) carbide burrs have a right-handed (Up cut) spiral flute.
Carbide Burrs Commonly Come in Two Cuts Single Cut and Double Cut See Our Complete Carbide Rotary Burrs RangeĢ. They are used in the aerospace, automotive, dental, metal sculpting, and metal smith industries to name but a few. Helpful note: Always use a handpiece that runs true (with no wobble) Who Uses Carbide Burrs?Ĭarbide burrs are widely used for metalwork, tool making, engineering, model engineering, wood carving, jewellery making, welding, chamfering, casting, deburring, grinding, cylinder head porting and sculpting. Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools such as a Dremel. Die Grinders, Pneumatic rotary tools and high speed engravers.
