If you are looking for an Oregon 511A or other similar grinder, look no further – there is a new grinder in town and it blows away the Oregon grinders. Here is why:
As many of you know, UL (Underwriters Laboratories) have forced all chain grinder manufacturers to eliminate bi-directional grinding due to the fact that the sparks produced when grinding left hand cutters fly directly in your face.
Many tourists still want the ability to grind the cutters (both left and right) into the cutter without a burr out at the cutting surface area.
This is now impossible to do with the newer Oregon 511A grinders. To solve this problem, AMA has just come out with the Italian-made MAXX Professional Grinder Model 750, now available in the US.
The head on these grinders tilts both left and right and the table is fully symmetrical, allowing you to get the same results on both left and right hand cutters.
