CSJ Crown Drill Bit, 6D Drill Diameter Range 15.00-15.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Product Overview

Short Description

The CSJ Crown Drill Bit (6D) is a premium high-speed indexable insert drill designed for high-efficiency, deep-hole drilling. Featuring a versatile Ø15.00mm–15.99mm diameter range, a secure front-locking body, and an advanced internal cooling system, this tool delivers maximum stability, superior chip evacuation, and exceptional precision in demanding industrial applications.

Product Features & Introduction

Engineered for ultimate performance, the CSJ Crown Drill Bit series redefines deep-hole drilling efficiency. By combining a rigid side-locking drill tip with an innovative front-locking body mechanism, this indexable tool ensures zero-slip operation and rapid insert replacement directly on the machine—minimizing downtime.

Its optimized 6D flute length is crafted to handle deep bores effortlessly, while the integrated thru-coolant channels deliver coolant straight to the cutting edge. This drastically reduces thermal stress, extends tool life, and ensures flawless chip evacuation even in sticky or high-strength materials.

Key Functions & Benefits

• High-Speed Deep Drilling: The rigid 6D body design allows for high-feed, deep-hole drilling without compromising structural integrity or hole straightness.

• Efficient Internal Cooling: Dual internal coolant holes flush out chips instantly from the bottom of the hole, preventing chip recutting and localized overheating.

• Rapid Tool Changes: The front-locking system allows operators to change the crown drill tip quickly without removing the entire drill body from the holder.

• Cost-Effective Indexable Design: No need to regrind. Simply replace the worn crown tip to restore 100% cutting efficiency, drastically reducing per-hole tooling costs.
