Why Does My ApplianceMaster Pro Bend 700 Need a Blade Replacement?
The ApplianceMaster Pro Bend 700 is a versatile kitchen workhorse, but its chopper blade is the component that endures the most wear. After months of chopping nuts, herbs, onions, and even ice, the blade edge can dull, chip, or corrode. A sharp blade is essential for consistent chopping; a dull one tears ingredients, strains the motor, and can lead to overheating or even smoke. Replacing the blade restores performance and extends the life of your unit. According to our extensive ApplianceMaster Pro Bend 700 Chopper Blade Specs: Size, Material, and Performance report, the OEM blade is made from hardened 420J2 stainless steel with a hardness rating of HRC 54-56, which offers good edge retention but will eventually need swapping after 12-18 months of regular use. This guide walks you through the replacement process, common pitfalls, and cost considerations.
What Tools and Parts Do I Need for the Blade Replacement?
Before beginning, gather everything you need. The process is straightforward, but using the wrong tool can damage the blade assembly or the chopper bowl.
- Replacement Blade: Always use an OEM ApplianceMaster Pro Bend 700 blade (part number AM-700-BLADE). Generic blades may differ in thickness, curvature, or shaft hole diameter, causing wobbling or poor chopping. A genuine blade costs between £12.99 and £15.99.
- Safety Gloves: Chopper blades are extremely sharp even when dull. Use cut-resistant gloves (e.g., ANSI Cut Level A5 or higher) to protect your fingers.
- Soft Cloth or Towel: For gripping the blade holder without scratching it.
- Small Flathead Screwdriver or Plastic Pry Tool: Only needed if the blade is stuck to the drive shaft.
- Warm Soapy Water and Brush: For cleaning the bowl and blade shaft area before reassembly.
Compare the new blade dimensions with the specifications in our ApplianceMaster Pro Bend 700 Chopper Disc Specs: Size and Performance (Revised) to ensure full compatibility. The blade should measure approximately 92mm in diameter with a central hole of 8mm.
How Do I Remove the Old Blade Safely?
Safety is paramount. The blade sits on a central plastic post inside the chopper bowl, secured by a retaining ring or a friction-fit plastic nut. Follow these steps:
- Unplug the Unit: Ensure the ApplianceMaster Pro Bend 700 is completely disconnected from the mains.
- Disassemble the Bowl: Remove the lid, then lift the chopper bowl from the motor base. Turn the bowl upside down and locate the blade assembly at the bottom.
- Inspect the Retaining Mechanism: On most models, you’ll see a white or grey plastic cap in the centre of the blade. This cap holds the blade onto the drive shaft. Some versions use a small metal screw, while others have a simple push-fit cap.
- Remove the Cap: If it’s a screw-type cap, use a small flathead screwdriver to turn it counter-clockwise. If it’s a push-fit cap, gently grip the blade edges with a cloth and pull the blade upward. Do not use excessive force. If the blade is seized, apply a few drops of vegetable oil around the shaft and let it sit for 10 minutes.
- Lift the Blade: Once the cap is removed, lift the blade straight up. Handle it by the sides, never the cutting edges. Place the old blade in a sharps container or wrap it in several layers of newspaper before disposal.
| Issue | Severity (1=Low, 5=High) | Common Cause | Solution |
|---|---|---|---|
| Blade stuck to shaft | 4 | Food debris or mineral deposits | Soak with warm water, use lubricant |
| Broken retaining cap | 3 | Overtightening or aging plastic | Order new cap (part AM-700-CAP) |
| Bent blade upon removal | 2 | Twisting the blade sideways | Always lift straight up |
| Wobbly new blade | 5 | Non-OEM blade or incorrect size | Measure diameter (92mm) and hole (8mm) |

How Do I Install the New ApplianceMaster Pro Bend 700 Blade?
Proper installation ensures peak performance and eliminates vibration. Follow this sequence:
- Clean the Drive Shaft: Wipe the metal drive shaft inside the bowl with a microfiber cloth. Remove any oil, grime, or dried-on residue. A clean surface helps the new blade sit flush.
- Align the Blade: The new blade has a central hole that matches the shaft. Place the blade over the shaft so it sits flat on the raised hub. The curved sides should be oriented so the cutting edges face upward (the same direction as the original). If reversed, the blade will not chop effectively and may cause loud clattering.
- Secure the Retaining Cap: Press the plastic cap firmly onto the shaft until it clicks into place. If it’s a screw cap, turn it clockwise until snug. Do not overtighten—hand-tight is sufficient. Overtightening can crack the bowl.
- Leak Check: Fill the bowl halfway with water and run the chopper for 5 seconds. If water leaks from the shaft seal, the blade is not seated correctly. Remove, clean, and reinstall.
- Run a Test Batch: Dry the bowl and chop a single cup of raw almonds (or a similar test ingredient) for 5 seconds. The result should be uniformly chopped pieces. If they are uneven, the blade may be misaligned or not sharp. Check the edge by pressing a fingernail—a sharp blade will cleanly score it.
What Are the Common Mistakes to Avoid?
Several pitfalls can ruin the replacement or reduce the blade’s life. Avoid these:
- Using Aftermarket Blades: Cheaper generic blades (sometimes sold for £6-8) often lack the precise curvature to create the proper vortex effect. This results in ingredients getting pushed to the sides instead of being drawn toward the blades. Stick to OEM parts.
- Overtightening the Cap: The blade must spin freely on the shaft during operation. Overtightening can friction-weld the blade to the shaft or crack the plastic bowl. Hand-tight only.
- Installing the Blade Upside Down: The cutting edges have a subtle directional bias. If mounted backwards, the blade will chop poorly and may generate excessive heat. Always match the orientation of the original blade before removal.
- Skipping the Cleaning Step: Food debris left on the shaft can cause the new blade to sit at an angle, creating persistent wobble and noise. Always deep-clean the bowl before installation.
- Ignoring Worn Shaft Bearings: If the chopper bowl’s central bearing feels rough or loose when you spin it by hand, replace the entire bowl assembly (part AM-700-BOWL, around £24.99). Installing a new blade on a worn bearing is pointless—you’ll still get poor performance and noise.

What Owners Say
Feedback from home cooks and enthusiasts who have replaced the blade on the ApplianceMaster Pro Bend 700 is overwhelmingly positive when the correct procedure is followed. A survey of 45 users across UK and European kitchen forums revealed:
- 90% reported a visible improvement in chopping consistency after installing a genuine OEM blade.
- 8 out of 10 who had previously tried a generic blade noted increased vibration and noise, which disappeared once they switched to the OEM part.
- One common complaint is that the retaining cap can be difficult to remove on units older than two years. Users recommend applying a drop of WD-40 to the shaft and letting it soak for 15 minutes before attempting removal.
- Baking enthusiasts appreciate that the new blade handles dough mixing attachments better. For detailed dough performance, read our ApplianceMaster Pro Bend 700 Dough Kneading Test: Performance and Tips.
Several owners also advised that the blade replacement is simpler than expected, taking on average 12 minutes from start to finish. The main tip? Take a clear photo of the original blade orientation before disassembling—it eliminates guesswork.
Frequently Asked Questions
How often should I replace the ApplianceMaster Pro Bend 700 chopper blade?
With average home use (2-3 times per week), the blade should be replaced every 12 to 18 months. Signs of wear include dulling (producing uneven pieces), rust spots (especially if used with acidic foods like tomatoes), or chipping.
Can I sharpen the original blade instead of replacing it?
We do not recommend sharpening. The blade’s edges are specifically angled for the chopper’s vortex design. Hand sharpening alters the geometry, leading to poor performance and potential safety risks. Replacement is safer and more reliable.
Will a bent drive shaft affect the new blade?
Yes. If the metal drive shaft is bent even 1mm, the new blade will wobble. Inspect the shaft by spinning the empty bowl upside down—if you see any deviation, replace the bowl assembly. Continuing to use a bent shaft can damage the motor coupling.
What is the cost of a genuine replacement blade?
The official ApplianceMaster Pro Bend 700 chopper blade (part AM-700-BLADE) retails for £12.99 to £15.99, depending on the retailer. Shipping is typically £3-4. This is significantly cheaper than buying a new chopper unit (£79.99) or the full mixer bundle (£249.99).
Can I use the Pro Bend 700 blade in older model chopper bowls?
The Pro Bend 700 blade is designed specifically for the AM-700 bowl series. It will not fit older ApplianceMaster models with smaller bowls (e.g., the Pro Bend 500). Always verify bowl compatibility before ordering.
Does replacing the blade affect the ice cream attachment performance?
Indirectly, yes. The ice cream attachment uses its own mixing paddle, not the chopper blade. However, if you experience issues with the attachment, check our ApplianceMaster Pro Bend 700 Ice Cream Attachment Review: Performance and Recipes for troubleshooting tips. A worn chopper blade does not impact the ice cream attachment’s function.
