Notes
- We’ve produced drill bits and chisels for 22+ years. Only original YG8C carbide is used (never recycled).
- 40Cr is tougher than common 45# steel; for example, a 6 × 160 mm bit can drill 150+ holes (results vary by tool and substrate).
- Colors may appear different depending on your monitor.
