CSJ Crown Drill Bit,10D Drill Diameter Range 37.00-37.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Short Description

The CSJ 10D Front-Locking Crown Drill Bit is a high-performance, indexable insert deep-hole drilling tool engineered for high-speed precision machining. Featuring an internal cooling system, side-locking tip mechanism, and front-locking body design, it ensures excellent chip evacuation, maximum dynamic stability, and extended tool life when drilling at aspect ratios up to 10xD within the 37.00–37.99 mm diameter range.

Product Overview (Product Description)

Designed for challenging heavy-duty and deep-hole drilling applications, the CSJ 10D Crown Drill Bit combines rigid structural strength with efficient heat management. Its innovative front-locking body coupled with a side-locking replaceable tip/insert mechanism guarantees precise indexing accuracy and fast, hassle-free head replacement directly on the spindle, drastically reducing setup downtime.

Equipped with localized internal coolant channels, the drill delivers high-pressure coolant directly to the cutting zone, facilitating smooth chip evacuation, preventing thermal expansion, and maintaining surface integrity during high-speed, continuous 10D deep-hole operations.

Key Specifications (Product Parameters)

Functions & Advantages (Product Features & Functions)

• High-Speed 10D Deep Drilling: Maintains rigid stability and straightness without drift during extreme 10xD depth-to-diameter ratio drilling operations.

• Internal Coolant Channel: Directly flushes chips out of the flutes while instantly cooling the cutting edges, preventing thermal stress and micro-cracking.

• Front & Side-Locking Mechanism: Enables quick, high-precision insert head replacements without requiring complete tool assembly teardown.

• Cost Efficiency: Utilizes replaceable indexable crowns, significantly reducing per-hole tooling costs compared to solid carbide or conventional drills.

• Superior Surface Finish: Smooth chip removal minimizes wall friction and scoring, resulting in high-precision hole finishes.

Application Scenarios

• Heavy Machinery & Equipment: Drilling deep oil, gas, and hydraulic cylinder passage holes in heavy machinery frames.

• Mold & Die Manufacturing: Precise cooling channel line drilling in large-scale plastic injection molds and stamping dies.

• Wind Power & Energy Sector: Machining large flange mounting holes, hub components, and pressure vessel plates.

• Automotive & Commercial Vehicles: Machining heavy engine blocks, gear shafts, transmission housings, and axle components.
