CSJ Crown Drill Bit,10D Drill Diameter Range 32.00-32.99, 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 (10D, Ø32.00–32.99mm) is a high-performance indexable insert drill engineered for deep-hole drilling up to 10 times the drill diameter. Featuring a rigid front-locking body with internal cooling and a side-locking drill tip, it delivers exceptional chip evacuation, high-speed stability, and extended tool life in heavy-duty machining operations.

Product Description

Designed for demanding industrial manufacturing, the CSJ Crown Drill Bit (10D Series) is the ultimate solution for precision deep-hole drilling. Engineered to cover a hole diameter range from 32.00mm to 32.99mm, this high-efficiency indexable drill combines a durable alloy steel body with a secure front-locking mechanism to maintain tight tolerances and minimize vibration.

Equipped with internal cooling channels, the tool directs high-pressure coolant directly to the cutting edge, rapidly lowering temperatures and clearing chips away during deep penetration. The side-locking drill tip allows for quick, seamless insert changes without removing the tool body from the machine holder—drastically reducing downtime and boosting overall production efficiency.
