SA-3 cylinder shape burrs are good for interior contour work and deburring. Because of the extreme hardness with this tungsten carbide, you can use it on a lot more demanding jobs than HSS (High-Speed Steel).

Double cut or Cross cut carbide burrs usually are applied to ferrous and non-ferrous metals, soft steel, as well as for all non-metal materials such as stone, plastics, wood floor, and ceramic. Double cut burrs leaves a slightly smoother finish than single cut on account of producing smaller chips since they cut away the pad. Use for medium stock removal, deburring, finishing, and cleaning. A double-cut carbide burr is easily the most popular cut and may look at you through most applications.

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
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 are using your burr on. If you are experiencing chipping, you are most probably operating at excessive of speed for your application. Start having a slower speed and increase in the process before you get the ideal results

Apply light pressure and let the tool perform the work. Bearing documented on the tool will result in reduced tool life as well as a dull burr.

Always wear proper PPE to feature (but not limited by) safety glasses, hearing protection, respirator, and hand protection. Keep all guards in place on the machine.

Avoid experience electrical energy drills; the slower speeds may result in chipping of the workpiece.
