Product Parameters

Product Features & Benefits

• High-Speed Deep-Hole Drilling: Optimized for 5D depth-to-diameter ratios, delivering stable and rapid penetration without compromising hole accuracy.

• Front-Locking & Side-Locking Design: The secure front-locking mechanism combined with a side-locking drill tip guarantees exceptional clamping force, reducing vibration and ensuring high repeatability.

• Advanced Internal Cooling: Dual internal coolant holes deliver high-pressure fluid directly to the cutting edge, drastically reducing heat buildup and flushing chips out smoothly.

• Cost-Effective Indexable Design: No need to regrind the entire tool; simply replace or index the crown drill tip to minimize downtime and reduce tooling costs.
