CSJ Crown Drill Bit, 5D Drill Diameter Range 19.00-19.99, 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) is a high-performance, indexable deep-hole drilling solution designed for precision and speed. Featuring a front-locking body, an innovative side-locking drill tip, and integrated internal cooling, it delivers exceptional chip evacuation and extended tool life across a diameter range of 19.00mm – 19.99mm.

Product Introduction

Engineered for demanding industrial applications, the CSJ Crown Drill Bit redefines high-speed, deep-hole drilling efficiency. This 5D indexable insert drill combines the structural rigidity of a solid carbide drill with the cost-efficiency of replaceable crown inserts. Its advanced front-locking body coupled with a secure side-locking drill tip ensures maximum stability, minimizing vibration even under high-torque conditions. Equipped with dual internal coolant channels, it directs coolant precisely to the cutting edge, drastically reducing thermal stress and ensuring seamless chip evacuation.

Product Features & Functions (Product Roles)

• High-Speed 5D Deep-Hole Drilling: Easily handles drilling depths up to 5 times the drill’s diameter with flawless precision.

• Dual-Locking Stability: The combination of a front-locking body and a side-locking tip guarantees zero insert movement, enhancing hole accuracy and surface finish.

• Internal Cooling System: Delivers high-pressure coolant directly to the cutting zone, lowering temperatures, preventing chip clogging, and prolonging tool life.

• Cost-Efficient Indexable Design: No need for regrinding. Simply replace the crown insert or drill tip to maintain peak performance, drastically reducing downtime and tooling costs.
