SA-1 cylinder shape burrs are good 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 of tungsten carbide burr die grinder bits and definately will will soften at higher temperatures, so carbide is always the best choice for long-term performance.
Double cut or Cross cut carbide burrs usually are used on ferrous and non-ferrous metals, soft steel, and for all non-metal materials like stone, plastics, wood, and ceramic. Double cut burrs leaves a slightly smoother finish than single cut as a result of producing smaller chips since 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 may look at you through most applications.
Cut – Double Cut
Max RPM – 70,000, yet it’s uncommon to wish over 35,000 RPM.
Machines Used On:
Die Grinders and hand-held pneumatic grinders
Application:
Ferrous Materials – Cast Iron, Steel, Stainless, Steel, Titanium, Nickel, Wrought Iron
Non-Ferrous Materials – Copper
Other Materials – Fiberglass, Plastic, Hard Rubber, Wood, Stone
Cylinder Shape burrs are great for interior contour work like peripheral and face milling.
Safety Tips & Techniques:
Tool speed is determined with the material you use your burr on. If you’re experiencing chipping, you are most likely operating at way too high of speed for your application. Start using a slower speed while increasing as you go along and soon you achieve the ideal results
Apply light pressure and allow the tool perform the work. Bearing documented on the tool will lead to reduced tool life as well as a dull burr.
Always wear proper PPE to include (but not limited to) safety glasses, hearing protection, respirator, and hand protection. Keep all guards in position in your machine.
Avoid use on electric power drills; the slower speeds can lead to chipping of one’s workpiece.
