Carbide Burrs (often known as Rotary Burrs) can be used cutting, shaping, grinding but for the elimination of sharp edges, burrs and excess material (deburring).
1. What material can Carbide Burrs be used on?
Carbide burrs may be used on many materials. Metals including steel, aluminum and iron, all sorts of wood, acrylics, fibreglass and plastics. When suited for soft metals including gold, platinum and silver, carbide burrs are excellent as they can last a long time with no chipping or breaking.
Steel, Carbon Steel & Stainless
Iron
Aluminium
Titanium
Cobalt
Nickel
Gold, Platinum & Silver
Ceramics
Fibreglass
Plastic, Carbon Fiber Reinforced Plastic (CRP), Glass Fibre Reinforced Plastic (GRP)
Brass, Copper & Bronze
Zinc
Wood
Different cuts of carbide burrs will be ideal to specific materials, understand the next point below to discover more on the several cuts.
What can You have Carbide Burrs In?
Ideally carbide burrs are used in Air Tools i.e Die Grinders, Pneumatic rotary tools and speed engravers. Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools say for example a Dremel.
Use a handpiece that runs true i.e without any wobble.
Who Uses Carbide Burrs?
Carbide burrs are trusted for metalwork, tool making, engineering, model engineering, wood carving, jewellery making, welding, chamferring, casting, deburring, grinding, cylinder head porting and sculpting. And so are found in the aerospace, automotive, dental, metal sculpting, and metal smith industries to name just a few.
2. Carbide Burrs Commonly Come in Two Cuts; Single Cut and Double Cut (Diamond Cut)
Single cut (one flute) carbide burrs have a very right handed (Up cut) spiral flute. These usually are in combination with metal, hardened steel, copper, surefire, and ferrous metals and may remove material quickly using a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.
Heavy elimination of material
Milling
Deburring
Cleaning
Creates long chips
Double cut carbide burrs usually are suited for ferrous and non ferrous metals, aluminium, soft steel and for all non-metal materials like plastics and wood. They’ve got more cutting edges and may remove material faster. Double cut are often referrred to as Diamond Cut or Cross Cut (2 flutes cut across each other) leaves a smoother finish than single cut on account of producing smaller chips as they cut away the information. Use for medium-light stock removal, deburring, finishing and cleaning. A dual cut carbide burr is the most popular cut and definately will help you through most applications.
Medium- light removal of material
Deburring
Fine finishing
Cleaning
Smooth finish
Creates small chips
3. What Speed or RPM the use of your Carbide Burrs?
The speed from which you employ your carbide bur with your rotary tool will depend on the pad you use it on and also the contour being produced however it is safe to say you do not need to exceed speeds of 35,000 RPM.
4. Do Not Apply Excessive Pressure
As with most drill bits and burrs, allow burr perform work and apply just a little pressure otherwise the cutting edges of the flutes will chip away or become smooth too rapidly, lowering the life span of your burr.
5. Carbide Burrs are Harder Than HSS Burrs
Our Carbide Burrs are machine ground from the specially chosen grade of carbide. Due to the extreme hardness from the Tungsten Carbide they are often utilized on much more demanding jobs than HSS (High Speed Steel).
Carbide Burrs also perform better at higher temperatures than HSS so you can run them hotter, as well as longer.
HSS burrs will begin to soften at higher temperatures so carbide is usually a better option for very long term performance.
What Are The Attributes of Tungsten Carbide Burrs?
Long life
Use for long production runs
High stock removal
Ideal for using on many hard and tough materials
Ideal for Deburring, finishing, carving, shaping and smoothing welds, moulds, dies and forgings
6. Maintain the Carbide Burr On the road
When working with your carbide burr don’t ensure that it stays still for days because this prevents the burr from digging and jabbing in your material causing unsightly marks and roughness.
End with an ‘up’ stroke to get a smoother finish to your work.
Stay Safe:
Always make sure your burr shank is well inserted to your collet and clamped down tightly
Keep pressure light whilst the bur moving, concentrating on the highest material first
Ensure your jobs are secured tightly to your workbench
Don’t snag or jam your burr in your work
Wear eye protection at least, but on top of that utilize a full shield on your face
