SA-1 cylinder shape burrs are perfect for interior contour work and deburring. Due to the extreme hardness on this tungsten carbide, quite a few on much more demanding jobs than HSS (High-Speed Steel). These carbide burrs are constructed of tungsten carbide burr die grinder bits and can learn to soften at higher temperatures, so carbide is obviously the best option for long-term performance.
Double cut or Cross cut carbide burrs usually are applied to ferrous and non-ferrous metals, soft steel, and for all non-metal materials including stone, plastics, real wood, and ceramic. Double cut burrs leaves a rather smoother finish than single cut due to producing smaller chips because 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 will see you through most applications.
Cut – Double Cut
Max RPM – 70,000, however it’s uncommon to need more than 35,000 RPM.
Machines Applied to:
Die Grinders and hand-held pneumatic grinders
Application:
Ferrous Materials – Cast Iron, Steel, Stainless, Steel, Titanium, Nickel, Wrought Iron
Non-Ferrous Materials – Copper
Many other materials – Fiberglass, Plastic, Hard Rubber, Wood, Stone
Cylinder Shape burrs are ideal 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 are experiencing chipping, you are most likely operating at too much of speed to the application. Start with a slower speed and increase in the process and soon you get the the best results
Apply light pressure and allow the tool carry out the work. Bearing upon the tool can lead to reduced tool life as well as a dull burr.
Always wear proper PPE to include (and not limited to) safety glasses, hearing protection, respirator, and baseball gloves. Keep all guards in place on the machine.
Avoid use on electrical energy drills; the slower speeds can lead to chipping of your workpiece.
