Product Overview

Short Description

The CSJ Crown Drill Bit (6D, Ø17.00–17.99mm) is a high-performance, indexable deep-hole drilling solution engineered for speed and precision. Featuring an advanced front-locking body and integrated internal cooling, this side-locking crown drill ensures exceptional chip evacuation, extended tool life, and maximum stability during demanding high-speed machining operations.

Product Introduction

Designed to bridge the gap between solid carbide drills and traditional indexable insert drills, the CSJ Crown Drill Bit offers the ultimate combination of cost-efficiency and high productivity. With a 6D depth capability and a precise 17.00–17.99mm diameter range, its innovative front-locking system allows for rapid tip replacement directly on the machine, minimizing downtime. Supported by specialized internal coolant channels, it delivers superior performance in deep-hole applications by keeping temperatures low and maintaining rigid alignment.

Key Features & Functions

High-Speed Deep-Hole Drilling (6D): Seamlessly drills depths up to six times its diameter without sacrificing accuracy or hole straightness.
Advanced Front-Locking System: Features a highly rigid side-locking tip mechanism that secures the crown insert, resisting high torsional forces while enabling quick, hassle-free tip changes.
Internal Cooling Channels: Dual internal coolant holes deliver high-pressure fluid directly to the cutting edge, effectively lowering thermal stress and flushing chips out of deep holes.
Cost-Efficient Indexable Design: Eliminates the need for regrinding. When the cutting edge wears out, simply replace the crown tip to restore brand-new drilling performance.

Target Applications & Industries

The CSJ Crown Drill Bit is highly versatile and engineered for heavy-duty metalworking across various manufacturing sectors:

Automotive Industry: Precision drilling for engine blocks, crankshafts, and powertrain components.
Aerospace & Defense: Machining high-strength alloys for structural frames and landing gear.
Heavy Machinery & Energy: Deep-hole drilling for hydraulic cylinders, tube sheets, and wind turbine components.
