Carbide Burrs (also called Rotary Burrs) bring cutting, shaping, grinding and for the removal of sharp edges, burrs and excess material (deburring).
1. What material can Carbide Burrs be used on?
Carbide burrs can be used on many materials. Metals including steel, aluminum and iron, all types of wood, acrylics, fibreglass and plastics. When utilized on soft metals like gold, platinum and silver, carbide burrs are ideal because they will last quite a long time without any chipping or breaking.
Steel, Carbon Steel & Stainless-steel
Cast Iron
Aluminium
Titanium
Cobalt
Nickel
Gold, Platinum & Silver
Ceramics
Fibreglass
Plastic, Graphite Reinforced Plastic (CRP), Glass Fibre Reinforced Plastic (GRP)
Brass, Copper & Bronze
Zinc
Wood
Different cuts of carbide burrs will be ideal to certain materials, understand the next point below to discover more regarding the different cuts.
Exactly what do You Use Carbide Burrs In?
Ideally carbide burrs are employed in Air Tools i.e Die Grinders, Pneumatic rotary tools as well as speed engravers. Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools for instance a Dremel.
Only use a handpiece that runs true i.e without having wobble.
Who Uses Carbide Burrs?
Carbide burrs are traditionally used for metalwork, tool making, engineering, model engineering, wood carving, jewellery making, welding, chamferring, casting, deburring, grinding, cylinder head porting and sculpting. And so are utilized in the aerospace, automotive, dental, metal sculpting, and metal smith industries to mention just a few.
2. Carbide Burrs Commonly Come in Two Cuts; Single Cut and Double Cut (Diamond Cut)
Single cut (one flute) carbide burrs use a right handed (Up cut) spiral flute. These usually are used in combination with stainless, hardened steel, copper, certain, and ferrous metals and definately will remove material quickly using a smooth finish. Use for heavy stock removal, milling, deburring and cleaning.
Heavy removal of material
Milling
Deburring
Cleaning
Creates long chips
Double cut carbide burrs are generally applied to ferrous and non ferrous metals, aluminium, soft steel as well as for all non-metal materials such as plastics and wood. They’ve got more cutting edges and may remove material faster. Double cut are now and again referrred to as Diamond Cut or Cross Cut (2 flutes cut across the other person) will leave a smoother finish than single cut because of producing smaller chips since they cut away the pad. Use for medium-light stock removal, deburring, finishing and cleaning. A double cut carbide burr is regarded as the popular cut and may view you through most applications.
Medium- light elimination of material
Deburring
Fine finishing
Cleaning
Smooth finish
Creates small chips
3. What Speed or RPM the use of your Carbide Burrs?
The velocity at which you employ your carbide bur with your rotary tool will depend on the information you have it on and also the contour being produced but it’s safe to say you no longer need to exceed speeds of 35,000 RPM.
4. Usually do not Apply Excessive Pressure
As with all drill bits and burrs, permit the burr carry out the work and apply just a little pressure otherwise the cutting edges in the flutes will chip away or become smooth too rapidly, lowering the use of your burr.
5. Carbide Burrs are Harder Than HSS Burrs
Our Carbide Burrs are machine ground coming from a specially chosen grade of carbide. Due to extreme hardness with the Tungsten Carbide they could be utilized on considerably more demanding jobs than HSS (Very fast Steel).
Carbide Burrs also perform better at higher temperatures than HSS in order to run them hotter, as well as longer.
HSS burrs will start to soften at higher temperatures so carbide is definitely a better option for very long term performance.
Which are the Attributes of Tungsten Carbide Burrs?
Durability
Use for too long production runs
High stock removal
Ideal for using on many hard and tough materials
Well suited for Deburring, finishing, carving, shaping and smoothing welds, moulds, dies and forgings
6. Keep The Carbide Burr On The Move
When using your carbide burr never ensure that it stays still for too long as this minimizes the burr from digging and jabbing into your material causing unsightly marks and roughness.
End on an ‘up’ stroke to get a smoother finish to your work.
Stay Safe:
Always keep your burr shank is well inserted to your collet and clamped down tightly
Keep pressure light and make the bur moving, centering on the greatest material first
Keep your work is secured tightly on your work bench
Don’t snag or jam your burr into the work
Wear eye protection as a minimum, but better still make use of a full shield to your face
