CSJ Crown Drill Bit, 5D Drill Diameter Range 26.00-26.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

CSJ Crown Drill Bit (5D, Ø26.00–26.99 mm)

High-Speed, Front-Locking Indexable Insert Drill

Product Short Description

The CSJ Crown Drill Bit (5D) is a premium high-speed indexable insert drill engineered for deep-hole drilling. Featuring a diameter range of 26.00–26.99 mm and an innovative front-locking body with internal cooling, it delivers maximum stability, efficient chip evacuation, and exceptional precision in heavy-duty machining.

Product Introduction

Designed for modern CNC machining environments, the CSJ Crown Drill Bit combines the cost-efficiency of indexable inserts with the rigid performance of solid carbide drills. Its specialized side-locking drill tip / front-locking body mechanism allows for quick insert changes without removing the tool holder from the machine, drastically reducing downtime. Equipped with dual internal coolant channels, it thrives under the high-thermal demands of deep-hole drilling (5D depth-to-diameter ratio), ensuring a superior surface finish and extended tool life.

Product Parameters

Product Functions & Key Benefits (产品作用)

• High-Speed Deep Hole Drilling: Effortlessly achieves drilling depths up to 5 times the diameter (5D) while maintaining strict dimensional accuracy.

• Optimized Internal Cooling: Dual internal coolant holes deliver high-pressure fluid directly to the cutting edge, rapidly lowering temperatures and flushing out chips to prevent jamming.

• Ultra-Rigid Front-Locking Mechanism: The side-locking tip and front-locking body design secure the crown insert tightly, minimizing vibration and preventing deflection at high rotation speeds.

• Cost-Efficient Indexable Design: Eliminates the need for regrinding. When the cutting edge wears out, simply replace the drill tip insert to restore brand-new performance instantly.

Application Scenarios

This heavy-duty drilling solution is ideal for high-productivity industrial environments, including:

• Aerospace & Defense: Drilling deep structural holes in tough alloys like titanium and stainless steel.

• Automotive Manufacturing: Production of engine blocks, crankshafts, and heavy powertrain components.

• Heavy Machinery & Energy: Machining large tube sheets, pressure vessels, and wind turbine components.

• Mold & Die Industry: Efficient deep ejector-pin hole drilling in hardened die steels.

• Compatible Machinery: Fully optimized for CNC Machining Centers, Lathes with Live Tooling, and Boring Machines.
