Cutter Cartridge Advantage

How They're Different

How They're Different

One-piece monolithic elements replace thin individual cutter and spacer disks resulting in a drastic increase in cutter strength. Each cutter cross-section increases from approx. 5/16" to over 3.75", all but eliminating cracking and misalignment. The precision of these cutters is unequalled. In fact, unlike typical grinders, an entire 60" tall grinder stack can be assembled without misalignment, adjustment or shimming.

With Cutter Cartridge Technology, there's no Stack Re-tightening Required!

Made from One Solid Block of Alloy Steel

Made from One Solid Block of Alloy Steel

Six cutters and spacers are formed from one solid block of alloy steel. The result is far higher strength than individual cutter disks and no gaps between cutters to get contaminated and loosen.

1/12th the Cutter Parts

1/12th the Cutter Parts

With Cutter Cartridge Technology there are far less parts so unit reliability is greatly enhanced. With 1/12 the parts unit strength is more than doubled. With only a few cutters taking the place of banks of individual cutter and spacer disks, maintenance is made fast and easy.

Power to the Cutters

Power to the Cutters

Instead of having to assemble or disassemble multitudes of cutter and spacer disks, there is the advantage of the one-piece cutter cartridge. Each cutter bore has a broad surface engaging the shaft for solid transmission of power.

No Shaft Scoring

No Shaft Scoring

Because there's no thin cutters and spacers, shaft scoring is eliminated. This makes disassembly far easier and eliminates a major cause of grinder failures.
