Is your hair starting to pull and not cut smoothly? This is the first sign that it's time to replace the cutting blade. Before ordering – click the 'Check Model Compatibility' button at the top of the page and within seconds you will receive confirmation that the part is suitable for your machine.
Why does the cutting blade start pulling hair instead of cutting?
As the teeth wear down, they stop gripping the hair as sharply, creating a pulling sensation rather than a cutting sensation. Additionally, hair and moisture buildup between the teeth accelerates wear and tear and impairs efficiency. Replacing the blade restores the smooth cut, so it is the first action recommended when the haircut begins to feel uncomfortable.
A genuine part is important here because the teeth are manufactured with a precision finish that exactly matches the body of the machine and the accompanying comb. An unapproved replacement does not always maintain the exact spacing between the teeth, and therefore may catch hair or cause skin irritation.
The SKU is printed on the body of the machine or on the original product packaging, so you can verify compatibility before purchasing.

🔧 How do you replace the blade on the hair clipper?
Replacing it is a simple operation that takes about 1 minute, without screwdrivers and without any disassembly. Here's how to do it:
- Turn off the machine before replacing.
- If there is a release button on the machine body, press it to release the old knife.
- If there is no button, insert a finger under the teeth of the knife and gently pull it up.
- Remove the old knife and set it aside.
- Straighten the new original knife and insert the lower part into the machine body.
- Gently push the knife forward until you hear a click.
Risk reduction: Replacement requires no unscrewing or soldering – just a simple clip attachment. No need to disconnect any electrical connections, just turn off the machine.
💡 Tip from the experts
In Daniel’s experience, most customers replace the blade too late – only after it starts pulling hair rather than just cutting it. A tip that prevents premature wear: Apply a drop of special hairdressing blade oil to the teeth every few weeks. One minute of maintenance prevents rapid wear and extends the life of the blade.
❓ Frequently Asked Questions
How do you change a blade on a Philips hair clipper without tools?
Remove the old blade by pressing and pulling gently upwards, and attach the new blade until you hear a click. The operation takes about one minute and does not require a screwdriver or additional tool.
What is the difference between a covered knife and an unapproved substitute?
An original blade maintains precise spacing between the teeth and a perfect fit to the body of the machine and the comb. An unapproved replacement may catch hair, wear out faster, and cause skin irritation.
When should you replace the cutting blade?
When the machine starts to pull hair instead of cutting it smoothly, or when the haircut looks uneven. These are the most common signs that the teeth are worn and need to be replaced.
