CSJ Crown Drill Bit, 4D Drill Diameter Range 18.00-18.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Short Description

The CSJ Crown Drill Bit (4D) is a premium, high-speed indexable insert drill featuring a front-locking body and advanced internal cooling. Engineered for deep-hole drilling within an 18.00–18.99 mm diameter range, this side-locking drill tip system ensures exceptional stability, rapid chip evacuation, and maximum productivity in demanding industrial applications.

Product Overview

The CSJ Crown Drill Bit is designed to bridge the gap between solid carbide drills and indexable drills. Utilizing a specialized 4D length-to-diameter ratio, it delivers superior rigidity and precision when boring deep holes.

The innovative Front-Locking Body paired with a secure Side-Locking Drill Tip allows for quick, effortless insert changes directly on the machine, drastically minimizing downtime. Enhanced with dual Internal Cooling channels, this tool delivers coolant right to the cutting edge, effectively reducing thermal stress and ensuring seamless chip flushing during high-speed operations.
