SA-1 cylinder shape burrs are great for interior contour work and deburring. Due to the extreme hardness with this tungsten carbide, it can be used on a lot more demanding jobs than HSS (High-Speed Steel). These carbide burrs are made from tungsten carbide burr die grinder bits and definately will start to soften at higher temperatures, so carbide is usually a good choice for long-term performance.
Double cut or Cross cut carbide burrs tend to be applied to ferrous and non-ferrous metals, soft steel, and also for all non-metal materials for example stone, plastics, wood floor, and ceramic. Double cut burrs leaves a slightly smoother finish than single cut due to producing smaller chips as they cut away the fabric. Use for medium stock removal, deburring, finishing, and cleaning. A double-cut carbide burr is the most popular cut and definately will see you through most applications.
Cut – Double Cut
Max RPM – 70,000, yet it is uncommon to need greater than 35,000 RPM.
Machines Applied to:
Die Grinders and hand-held pneumatic grinders
Application:
Ferrous Materials – Surefire, Steel, Stainless, Steel, Titanium, Nickel, Wrought Iron
Non-Ferrous Materials – Copper
Many other materials – Fiberglass, Plastic, Hard Rubber, Wood, Stone
Cylinder Shape burrs are good for interior contour work like peripheral and face milling.
Safety Tips & Techniques:
Tool speed is determined by the material you’re using your burr on. If you might be experiencing chipping, you’re operating at too much of speed for your application. Start using a slower speed and increase on the way until you attain the the best results
Apply light pressure and allow tool perform work. Bearing documented on the tool will lead to reduced tool life plus a dull burr.
Always wear proper PPE to include (however, not limited to) safety glasses, hearing protection, respirator, and baseball gloves. Keep all guards available on your own machine.
Avoid experience electric power drills; the slower speeds may lead to chipping of the workpiece.
