Improved roundness, improved hole position accuracy, and improved straightness without being affected by casting holes!
The "IS-NVD" is an NV drill designed for machining core holes in a single pass. Thanks to its unique rough cutting edge wedge action, it suppresses behavior caused by misalignment of the core hole, allowing the finishing edge to achieve high precision in the inner diameter. Additionally, it is less affected by core misalignment, and by having four rough cutting edges, it reduces the load per edge. 【Features】 ■ The engagement angle is made concave to suppress contact during approach. ■ Improved roundness, hole position accuracy, and straightness. ■ Less affected by core misalignment. ■ Four rough cutting edges reduce the load per edge. ■ Suitable for machining hole requirement accuracy IT grade 7. ■ Available in diameters from Φ6 to Φ16. *For more details, please refer to the PDF document or feel free to contact us.
