Short Description

High-performance 10D indexable crown drill designed for deep-hole machining. Featuring a robust front-locking/side-locking mechanism and internal cooling channels, it delivers exceptional stability, superior chip evacuation, and high-speed precision drilling across tough materials.

Product Introduction

The CSJ Crown Drill Bit system is an advanced deep-hole drilling solution engineered for maximum efficiency and dimensional accuracy. Built for long-reach operations requiring a 10D depth-to-diameter ratio, it utilizes interchangeable crown tips in the range of 26.00 mm to 26.99 mm. The secure front-locking and side-locking mechanism ensures rigid insert clamping, minimizing vibration and radial runout during high-speed feed passes. Integrated internal coolant passages deliver high-pressure fluid directly to the cutting edge, rapidly lowering heat generation and flushing chips out of deep cavities smoothly to prevent tool breakage.
