CSJ Crown Drill Bit, 5D Drill Diameter Range 8.50-8.99, 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 (5D, Ø8.50–8.99mm) is a high-performance, front-locking indexable insert drill engineered for high-speed, deep-hole drilling. Featuring advanced internal cooling and a secure side-locking drill tip, it delivers exceptional precision, chip evacuation, and tool longevity in demanding machining environments.

Product Overview

The CSJ Crown Drill Bit series represents the pinnacle of deep-hole drilling technology. Designed with a 5D drilling depth capability and a versatile diameter range of 8.50mm to 8.99mm, this tool combines the rigidity of a solid carbide drill with the cost-efficiency of an indexable system.

Its innovative front-locking body and side-locking drill tip ensure maximum stability, eliminating vibration even during high-speed rotations. Equipped with dual internal cooling channels, the drill delivers coolant directly to the cutting edge, drastically reducing thermal stress and ensuring seamless chip evacuation.
