Customer feedback describes good quality, value and functionality, with one customer reporting success boring through M3 screws. However, size accuracy is mixed and breakage is a recurring concern. For buyers working with 1.5 mm PCB or small-component holes, the reported functionality may be relevant, but fragile bits and inconsistent size experiences make careful handling and tolerance-sensitive work important considerations.
Positive themes
- Customers describe the bits as good quality and functional.
- Some customers report good value for money.
Negative themes
- Customer feedback reports that the bits can break easily.
Mixed feedback
- Customers differ on whether the bits match the stated size.
