NV drill with oil holes designed based on Nichia Alloy's unique cutting theory.
The "OS-NVD" is an NV drill with oil holes that features sharp cutting edges all the way to the center of the drill. By adopting a center-through design, it provides significant cooling effects during cutting, and the unique shape of our vanishing drill enhances hole accuracy and surface precision through self-guiding. Additionally, the guide pad shape that enhances the vanishing effect and the center-through structure that ensures sufficient oil volume result in a wider margin width on the guide pad side. 【Features】 ■ Excellent cutting performance at the drill chisel part ■ Stable hole diameter even during high-speed machining ■ Minimal adhesion to the cutting edges, resulting in superior lifespan ・Additional oil holes: Maintains machining accuracy → IT7 level for deep hole machining up to five times the drill outer diameter ■ The lip section is designed with a focus on strength ■ Improved centering due to special thinning ■ Available in diameters from Φ5 to Φ16 *For more details, please refer to the PDF document or feel free to contact us.
