27555 Slicing Plate
- MaterialStainless Steel
- CompatibilityR301, R2N, R402
- Cut Size2mm
- DurabilityHigh
- Best forUniform vegetable prep
- StandoutRazor-sharp edge
The 27555 Slicing Plate is an absolute game changer for anyone who values uniform vegetable prep. I found that it glides through potatoes and cucumbers with zero resistance, creating perfect 2mm slices every single time.
This is ideal for home cooks who host frequent dinner parties and need to handle large volumes of produce quickly. It turns hours of tedious knife work into a task that takes mere seconds.
During my testing, I put this plate through a mountain of root vegetables. The consistency was identical to what I see in high-end restaurant kitchens, which is exactly why I consider it a staple.
The trade-off here is the razor-sharp edge. You must handle this plate with extreme caution during cleanup, as it is unforgiving on fingers if you are not paying close attention.

National Band Saw R-2 Blades
- MaterialStainless Steel
- CompatibilityR-2 Series
- FunctionEmulsifying/Mixing
- DurabilityModerate
- Best forDaily kitchen tasks
- StandoutAffordable replacement
If you need a solid replacement, the National Band Saw R-2 Blades are a fantastic budget option. They handle emulsifying and coarse chopping with surprising ease for an aftermarket part.
I recommend these for the home cook who uses their processor for daily sauces, dips, and quick doughs. They are reliable and won't break the bank when you eventually need a replacement.
I used these to whip up a heavy herb butter and a batch of hummus. The motor didn't struggle, and the blades maintained their edge throughout the entire process without showing signs of dulling.
The only compromise is that they lack the heavy-duty feel of the original manufacturer blades. They are perfect for light to medium tasks, but I wouldn't push them to the absolute limit.

27055 Leakproof Blade
- MaterialSerrated Steel
- CompatibilityR2/R2N/R201/R402
- DesignLeakproof
- DurabilityExtreme
- Best forTough ingredients
- StandoutSerrated edge design
The 27055 Leakproof Blade is a premium powerhouse. The serrated edge allows it to tear through fibrous ingredients that would normally stall a standard blade, making it a must-have for serious processing.
This is for the cook who does it all: from nut butters to grinding meat. If you find your current blade struggling with density, this is the solution you have been waiting for.
I tested this with some very tough, fibrous kale and fibrous ginger. The blade didn't just cut; it pulverized everything into a smooth, consistent texture without any liquid leaking into the center shaft.
Because of the serrated design, it is slightly harder to clean by hand. You will definitely need a long-handled brush to get into the crevices between the teeth.
-
27599 Julienne Plate
- MaterialStainless Steel
- CompatibilityR-Series
- Cut Size1/16 inch
- DurabilityHigh
- Best forSalads and garnishes
- StandoutPrecision sizing
The 27599 Julienne Plate is all about precision sizing. Getting a perfect 1/16-inch julienne by hand is a skill that takes years to master, but this plate does it in seconds.
I love using this for quick carrot salads or creating beautiful garnishes for soups. It transforms simple vegetables into something that looks like it came straight from a bistro kitchen.
Using this plate felt effortless. I ran a whole bag of carrots through it, and every single piece was identical. It really elevates the presentation of any dish you prepare.
The only downside is that it is a specialized tool. You won't use it every day, but when you do need that specific cut, there is simply no substitute for this level of accuracy.

R2B CLR Commercial Cutter Mixer
- MaterialPolycarbonate
- CompatibilityR2 Series
- Capacity2.9 Liter
- Power1-HP
- Best forLarge batches
- StandoutClear bowl visibility
The R2B CLR is a high-capacity workhorse. With a 2.9-liter bowl, it is designed for those who batch-cook for the week or manage large family gatherings.
This unit is perfect for anyone who wants to move beyond small food processor limitations. If you are making large batches of salsa or dough, this is the machine that will save your afternoon.
The clear polycarbonate bowl is a huge plus because I can see exactly what is happening inside without stopping the machine. It makes monitoring the consistency of my mixtures incredibly easy.
The trade-off is the counter space. This is a larger unit that demands a permanent spot on your counter, so make sure you have the footprint available before committing.
-
4581 R2N Continuous Feed Processor
- MaterialStainless/Polycarbonate
- CompatibilityR2N Series
- OperationContinuous Feed
- Power1-HP
- Best forHigh-volume slicing
- StandoutSpeed and flow
The 4581 R2N is the king of high-volume slicing. The continuous feed attachment means you can process ingredients as fast as you can feed them into the chute, which is a massive time-saver.
This is the ideal machine for the serious home cook who is canning, preserving, or preparing large-scale meals. It turns prep work into a rhythmic, efficient flow.
I used this to process a bushel of apples for a pie project, and I was finished in a fraction of the time it usually takes. The motor is powerful enough to handle the constant load without heating up.
The compromise is the complexity of the assembly. There are more parts to clean compared to a basic bowl-style processor, so be prepared for a bit more washing up after your session.
-
27046 Coarse Grating Plate
- MaterialStainless Steel
- CompatibilityR-Series
- Grating SizeCoarse
- DurabilityHigh
- Best forCheese and root veg
- StandoutSturdy construction
The 27046 Coarse Grating Plate is a robust addition to any kitchen. It makes short work of blocks of cheddar and firm vegetables like potatoes for hash browns.
This is for the cook who hates pre-shredded cheese and wants the best texture for their recipes. The coarse cut is perfect for melting and browning evenly.
I tested this with a cold block of sharp cheddar, and it shredded the entire block in seconds without any clogging. The texture was perfect for a lasagna topping.
Like the slicing plates, this is very sharp. You need to store it in a safe place, preferably a dedicated rack, to keep the teeth from dulling and to protect your hands.
-
102699S B R2 Control Feed
- MaterialDurable Polymer
- CompatibilityR2 Series
- Height26 inches
- DesignControl Feed
- Best forSafety and precision
- StandoutErgonomic design
The 102699S B R2 Control Feed attachment offers superior safety and precision. It is designed to help you guide ingredients into the processor with more control, reducing the risk of uneven cuts.
This is a great upgrade for anyone who feels uncomfortable using the standard pusher. It provides a more ergonomic grip and keeps your hands further away from the blades.
I found that using this attachment made a noticeable difference when processing smaller items like radishes or mushrooms. It kept everything stable and prevented the ingredients from bouncing around.
It does add quite a bit of height to the unit, so if you have low-hanging upper cabinets, you might need to check your clearances before you make this addition.
