Small Diameter Series (ø0.3 - ø0.55)
| Characteristic | Style | Size [mm] | |
| UC | UC is suitable for drilling small through-holes and mini-via holes for various purposes. It is also designed to improve the in-hole qualities (roughness, smear, etc.) while maintaining good hole registration accuracy. | Under cut type | ø0.3-ø0.55 |
| UV | UV was developed to satisfy the recent high demand for improve hole registration accuracy in small size hole drilling. It is especially suitable for high multi-layer and thin bases. | Under cut type | ø0.3-ø0.45 |
| NT | NT performs symmetric thinning with its two cutting edges at the tip, and due to this thinning, the thrust load is reduced considerably compared to conventional type. Consequently, the number of hits can be extended compared to conventional types. | Under cut type | ø0.3-ø0.55 |
