CSJ Crown Drill Bit, 4D 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

Product Short Description

The CSJ Crown Drill Bit (4D) is a high-performance, indexable deep-hole drilling solution designed for maximum efficiency and precision. Featuring a secure front-locking body and integrated internal cooling (thru-coolant), this side-locking indexable insert drill delivers exceptional chip evacuation and tool longevity. Engineered for high-speed operations, it covers a versatile drill diameter range of 26.00mm to 26.99mm at a 4D depth ratio, making it an indispensable tool for heavy-duty industrial machining.

Product Introduction

Elevate your machining capabilities with the CSJ Crown Drill Bit 4D Series. Built for demanding metalworking environments, this indexable insert drill bridges the gap between solid carbide drills and traditional indexable drills.

The advanced front-locking design allows for quick, seamless drill tip replacements directly on the machine, drastically minimizing downtime. Combined with its robust side-locking mechanism for unmatched tip stability and dual internal cooling channels that blast coolant directly to the cutting edge, this tool guarantees superior surface finishes, precise hole tolerances, and extended tool life even during high-speed, continuous deep-hole drilling.

Product Parameters (Specifications)

Product Functions & Key Benefits

• High-Speed Deep-Hole Penetration: The 4D length-to-diameter ratio enables rapid, deep-hole drilling without compromising structural rigidity or accuracy.

• Advanced Internal Cooling: Dual internal coolant holes deliver high-pressure fluid directly to the cutting zone, effectively lowering temperatures and preventing thermal deformation.

• Effortless Chip Evacuation: Optimized flute geometry combined with thru-coolant forces chips out of the hole instantly, eliminating chip packing and tool breakage.

• Rapid Tool Changes: The front-locking mechanism allows operators to replace the crown drill tip without removing the tool holder from the spindle, drastically boosting productivity.

• Maximum Rigidity: The side-locking drill tip configuration ensures zero slipping or micro-vibrations under heavy axial loads and high RPMs.
