Angle grinding the Litelok X3 and the Hiplok D1000

A few points about this video:

1. The angle grinder is a mains powered 720w Makita (GA5030R).

2. Despite trying to make this a laboratory style test, to determine which is the most angle grinder resistant, there are too many variables to make any definite conclusions: it was too close.

Another test may have different results. But both are extremely angle grinder resistant!
