TESTIMONIAL

We are currently running 1 -Big E-Z and 3- One Block systems, with the second Big E-Z on order. From day one, on both systems we were impressed with its smooth and vibration free cutting. After visiting The Keystone Facility, I knew why. The Drums are truly balanced and engineered from start to finish. We put over 2,000 hours on our Big E-Z before changing the inserts, and we are anticipating the same performance from our One Block Systems. (Our first One Block System is not to far from the 2,000 hour mark now). The level of customer service, quality and performance of their products will keep us buying Keystone's Drums. Proudly, made in the USA... it doesn't get any better than that!

Double R Squared

Double R Squared is a lacing pattern that has a repeating tooth at 180 degrees on the drum.
This allows you to almost double your forward speed and still maintains an excellent cutting pattern on the road surface.
Forward speeds of 160 feet per minute without V-ing out have been achieved.
Cutting with a broken or worn tooth can leave a bad pattern and cause damage to the bit holder, but with the Double R Squared the repeating tooth at 180 degrees cuts enough clearance to protect the bit holder of the broken or worn tooth.
