Short Description

The CSJ Crown Drill Bit (10D) is a high-performance indexable drilling tool engineered for high-speed, deep-hole processing. Featuring a 10×D drilling depth capability, a side-locking/front-locking drill tip mechanism, and internal cooling channels, it delivers exceptional chip evacuation, high rigidity, and superior hole accuracy across severe machining environments.

Product Introduction

Designed for deep-hole drilling operations requiring up to 10 times the drill diameter (25.00mm–25.99mm), the CSJ Crown Drill combines the structural stability of solid carbide drills with the cost-efficiency of indexable tooling. Its advanced front/side-locking mechanism ensures rapid tip replacement directly on the spindle without removing the tool body, significantly reducing setup downtime. The integrated internal cooling system delivers high-pressure coolant directly to the cutting edge, effectively lowering thermal load and clearing long chips during deep cavity penetration.

Product Functions & Key Advantages

Deep-Hole Efficiency (10D Ratio): Enables continuous 10D deep-hole processing in a single pass without pecking or pre-drilling pilot holes in standard conditions.
Front & Side-Lock Precision: Secure tip clamping minimizes radial runout and prevents body fatigue, allowing quick crown insert changes on-machine.
Internal Coolant Flushing: Pressurized coolant channels continuously cool the cutting zone and flush chips out of deep bores to prevent tool jam and fracture.
Cost Reduction: Retain and reuse the durable alloy steel drill body while replacing only the worn crown carbide insert tip.

Application Scenarios

Heavy Industry & Energy: Deep-hole boring for pressure vessel flanges, valve bodies, turbine hubs, and pipe sheets.
Automotive & Commercial Vehicles: Machining engine blocks, crankshaft passages, and heavy transmission shafts.
Mold & Die Manufacturing: Precise cooling channel line drilling in large injection molds and forging dies.
General Engineering: Precision hole making on CNC machining centers, horizontal boring mills, and heavy-duty CNC lathes.
