CSJ Crown Drill Bit,10D Drill Diameter Range 39.00-39.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Short Description

The CSJ 10D Crown Drill Bit (39.00 mm to 39.99 mm) is a high-performance indexable insert drill engineered for precision deep-hole machining. Featuring a dual front-locking and side-locking mechanism paired with an internal through-coolant system, it delivers superior chip evacuation, heat reduction, and exceptional tool stability during high-speed continuous drilling up to 10X diameter depth.

Product Introduction

The CSJ 10D Crown Drill Bit Body represents a heavy-duty modular tooling solution designed to maximize productivity in demanding metalworking applications. Built from heat-treated alloy steel, this indexable drill body accommodates interchangeable carbide crown tips within the 39.00 mm to 39.99 mm diameter range.

Its innovative front-locking and side-locking dual clamp structure ensures rigid tip positioning, minimizing runout and vibration even during interrupted cuts or tough material penetration. Integrated high-pressure internal coolant channels deliver fluid directly to the cutting zone, continuously flushing chips out of deep cavities to prevent tool binding and heat buildup. This cost-effective design allows shop operators to replace only worn crown inserts while retaining the durable drill body for long-term usage.

Product Specifications

Product Functions & Key Features

• 10D Deep-Hole Capability: Enables single-pass deep hole drilling up to 10 times the drill diameter without requiring pecking cycles or pre-drilled pilot holes in standard setup conditions.

• Rigid Dual-Locking System: The combination of front-locking body design and side-locking tip alignment minimizes tool deflection and runout under high feed rates.

• High-Pressure Internal Cooling: Direct internal coolant delivery optimizes chip breaking, flushes long chips out of deep bores, and extends edge life.

• Cost-Efficient Modular Concept: Reduces per-hole tooling costs by enabling quick insert changes directly on the machine spindle without taking off the drill body.

Application Scenarios

• Mold & Die Manufacturing: Deep cooling water channel line drilling in heavy injection molds and forging dies.

• Heavy Engineering & Machinery: Precision deep-hole boring on large structural steel frames, valve bodies, and hydraulic cylinders.

• Energy & Power Equipment: Holemaking in pressure vessel flanges, tube sheets, and wind turbine drive components.

• Automotive & Aerospace Subassemblies: High-volume deep drilling in alloy steel forging shafts and heavy vehicle engine blocks.

• Machining Centers & Boring Mills: Compatible with CNC lathes, vertical/horizontal machining centers (VMC/HMC), and horizontal boring machines equipped with high-pressure coolant units.
