The likely answer is no.  All the dies we sell are quality checked and cut well.  There are few things to try that will help you get a clean cut.

1. The Die should have the cut side facing UPWARDS not down so the card is pressed down into the die not the other way around.
2. Rotate the die – sometimes dies cut better at an angle in your die cut machine – try turning it or moving it to a different place in your machine. If you always place your dies in the same area on your machine this can slacken it over time.
3. Change your cutting plates – if the plates are overly warped this can prevent a clean cut.
4. Use a precision platform or metal shim.   Very intricate dies can benefit from these extra tools to get a clean cut.   If the centre of a die is still not cutting, a little washi tape stuck under that area of the die can add more pressure where needed.
5. Adjust the card thickness, or if cutting fabric add thin card behind to help the die bite.
