CSJ Crown Drill Bit, 6D 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

$1,231.0000

Product Overview

The CSJ Crown Drill Bit (6D) is a high-performance, indexable deep-hole drilling solution designed for extreme depth and high-speed precision. Featuring an advanced front-locking body mechanism paired with a specialized side-locking drill tip (crown entry), it ensures maximum stability, quick insert replacement, and zero body deflection. Engineered with internal cooling channels, this tool drives coolant directly to the cutting edges, drastically reducing heat generation and ensuring optimal chip evacuation during demanding 6D depth operations.

Key Functions & Benefits

High-Speed Deep Drilling (6D Capacity): Seamlessly drills holes up to six times its diameter without sacrificing structural stiffness or alignment precision.
Rapid Tip Replacement: The front-locking and side-locking hybrid system allows users to swap the indexable crown tip directly on the machine, minimizing downtime.
Advanced Thermal Management: Internal through-coolant holes blast high-pressure fluid directly onto the cutting zone, extending tool life and preventing thermal cracking.
Superior Chip Evacuation: Optimized flute geometry combined with internal cooling forces chips out of deep holes smoothly, preventing chip clogging and catastrophic tool failure.
