CSJ Crown Drill Bit,10D Drill Diameter Range 29.00-29.99, 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 (10D) is a high-performance modular deep-hole drill engineered for demanding high-speed drilling operations. Designed for a diameter range of ⌀29.00mm to ⌀29.99mm, this tool body features a front-locking / side-locking tip mechanism for swift insert indexing and maximum clamping rigidity. Built with internal coolant channels, it delivers continuous high-pressure coolant directly to the cutting zone, ensuring superior chip evacuation, low thermal stress, and maximum productivity in deep-hole metal cutting.

Product Description

Engineered for precision and heavy-duty performance, the CSJ Crown Drill Bit (10D Series) combines the high cutting speed of indexable tooling with the stability of solid carbide drills. Its innovative front/side locking mechanism enables quick head replacement directly on the machine spindle, significantly minimizing setup times and reducing production downtime.

The tool body incorporates dual internal coolant channels and optimized spiral flutes that flush chips out smoothly during deep 10D operations. Built from high-toughness alloy steel, it offers exceptional resistance to torsional stress and vibration, delivering high alignment accuracy, long tool life, and superb surface finishes across carbon steel, alloy steel, stainless steel, and cast iron applications.

Product Specifications & Parameters

Key Functions & Features

• 10D Deep-Hole Efficiency: Enables single-pass deep-hole drilling up to 10x diameter without requiring peck-drilling cycles, cutting machining time substantially.

• Internal Coolant Evacuation: Dual internal coolant jets cool the cutting edge directly, rapidly lowering operating temperatures and blasting chips out through the flutes.

• Quick-Change Tip Design: Secure front/side locking allows operators to replace worn carbide tips without dismounting the drill body from the holder.

• High Rigidity & Accuracy: Rigid insert clamping reduces tool deflection and runout, resulting in tighter hole tolerances and smoother wall finishes.

• Cost-Effective Operation: Reusable steel body paired with economical, replaceable carbide inserts drastically lowers per-hole tooling costs compared to solid carbide drills.

Applications

The CSJ Crown Drill Bit (10D, ⌀29.00–29.99mm) is ideal for high-precision, deep-hole drilling across heavy manufacturing sectors:

• Heavy Machinery & Power Generation: Drilling deep holes in structural frames, hydraulic cylinders, turbine plates, and large flanges.

• Mold & Die Manufacturing: Machining deep water cooling lines and ejector pin holes in injection molds and forging dies.

• Automotive & Aerospace Industry: Processing drive axles, engine blocks, transmission housings, and structural steel components.

• General CNC Machining: Suitable for vertical/horizontal machining centers (VMC/HMC), CNC lathes, and gantry milling machines running high-volume batch production.
