Highest Quality Chips
The helical knives of the USNR Norman Chipper slice uniform chips instead of scraping them from the stock, eliminating sawdust, slivers, and oversize split ends. The Norman design, termed the greatest development in chippers since their origin, has multiple helically ground faces which give a continuous cutting action similar to the advance of a propeller in water: chips are cut to uniform length along the whole length of the knife.
Fastest Feed Rates
In addition to high chip quality, this chipper design has an output capacity exceeding all others on the market. USNR Norman chippers have produced up to 125 units per hour with wood stock traveling through the dick at rates up to 800 lineal feet per minute.
