CSJ Crown Drill Bit,10D Drill Diameter Range 21.00-21.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Product Overview

The CSJ Crown Drill Bit is a high-speed, high-efficiency deep-hole drilling tool designed for heavy-duty industrial machining. Featuring a 10D drilling depth capacity and a front-locking body with internal cooling channels, this indexable insert drill delivers exceptional rigidity, chip evacuation, and thermal control. Its precision side-locking drill tip system ensures rapid insert changes, reduced downtime, and maximum stability during high-speed operation.

Product Features

• 10D Deep-Hole Capability: Engineered specifically for stable, high-aspect-ratio hole making without sacrificing accuracy or hole quality.

• Front-Locking & Side-Locking Tip Design: Ensures quick, rigid, and reliable insert clamping, minimizing runout and allowing fast on-machine tip replacements.

• Internal Coolant Channels: Directs high-pressure coolant straight to the cutting edge, effectively cooling the insert and flushing out chips in deep applications.

• High-Speed Indexable System: Uses replaceable crown/drill tips to lower overall tooling costs while maintaining production efficiency.

Product Specifications

Product Functions

• Deep Hole Drilling: Executes stable 10D hole creation in a single pass without pecking cycles.

• Thermal & Chip Management: Delivers coolant directly to the cutting zone to prevent heat buildup and prevent chip clogging in deep cavities.

• Rigid Tool Support: Absorbs heavy cutting forces during high-speed operations to ensure long tool life and strict dimensional tolerances.

• Tool Cost Reduction: Allows replacement of only the worn cutting tip/insert instead of replacing the entire body.

Applications

• Machining Operations: High-speed deep-hole drilling, core drilling, and through-hole machining on CNC lathes, milling machines, and machining centers.

• Target Industries: Heavy machinery, automotive manufacturing, aerospace components, mold and die fabrication, energy, and oil/gas tooling.

• Compatible Materials: Suitable for processing carbon steels, alloy steels, stainless steels, cast iron, and high-temperature alloys.
