CSJ Crown Drill Bit,10D Drill Diameter Range 36.00-36.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

1. Short Description

The CSJ 10D Crown Drill Bit (Ø36.00–36.99mm) is a high-performance indexable drilling tool engineered for heavy-duty, deep-hole drilling up to 10 times the hole diameter. Featuring a rigid front-locking body, internal through-coolant channels, and quick-change side-locking replaceable tips, it delivers superior hole accuracy, extended tool life, and minimum machine downtime.

2. Product Overview

The CSJ 10D Series Crown Drill Bit provides an efficient, cost-effective alternative to solid carbide or traditional U-drills for large-diameter deep-hole machining.

Designed for standard CNC milling centers, lathes, and boring machinery, this tool incorporates an internal coolant system that delivers high-pressure coolant directly to the cutting zone, ensuring fast chip evacuation and low thermal wear. Its quick-change crown tip system allows operators to index or swap drill inserts directly on the spindle without disturbing the tool shank setup, dramatically boosting throughput in high-volume production environments.

4. Key Functions & Features

• 10D High-Speed Deep-Hole Drilling: Effortlessly drills continuous deep holes up to 10× diameter while maintaining precise straightness and tight tolerances.

• Front-Locking Body Stability: High-rigidity steel alloy body absorbs cutting vibrations under high feed rates to ensure excellent hole surface finish and low runout.

• Through-Tool Internal Cooling: Channels high-pressure coolant directly to the cutting edges to instantly clear chips and prevent heat build-up.

• Fast Side-Locking Tip Indexing: Replaceable crown head locks tightly from the side, enabling quick tip changes without unmounting the holder from the machine spindle.

• Lower Operating Costs: Interchangeable crown inserts reduce overall tool inventory expenses compared to solid carbide drill replacements.

5. Applications & Use Cases

• Automotive & Heavy Machinery: Drilling engine cylinder blocks, transmission shafts, and hydraulic valve manifolds.

• Energy & Petrochemical: Deep-hole hole processing for oilfield valve blocks, pressure vessels, and thick structural steel flanges.

• Mold & Die Manufacturing: Deep cooling-channel drilling in large plastic injection molds and stamping dies.

• Compatible Equipment: Optimized for CNC machining centers, horizontal boring mills, CNC lathes, and specialized deep-hole drilling equipment.
