CSJ Crown Drill Bit,10D Drill Diameter Range 8.50-8.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

High-performance 10D indexable crown drill bit engineered for deep-hole drilling (diameter range 8.50–8.99 mm). Features an innovative front-locking body with internal cooling and a side-locking drill tip structure, delivering superior chip evacuation, high rigidity, and high-speed precision machining.

Product Description

The CSJ Crown Drill Bit is a premium deep-hole machining tool designed to meet demanding industrial standards. Engineered with an advanced 10D length-to-diameter ratio, it enables deep penetration without sacrificing stability or hole quality. The secure front-locking insert design combined with side-locking tip mechanisms ensures rapid tool changes, high repeat accuracy, and minimal vibration during heavy-duty operations. Integrated internal cooling channels flush out chips efficiently directly from the cutting edge, preventing thermal damage and significantly extending tool life.

Key Benefits & Functions

• Efficient Deep-Hole Processing: Effortlessly achieves up to 10D drilling depths with high straightness and minimal runout.

• Superior Thermal Management: Through-tool internal cooling lowers cutting temperatures, reduces tip wear, and optimizes chip evacuation.

• Quick-Change Efficiency: Front-locking and side-locking structural design allows fast insert replacement directly on the spindle, reducing setup downtime.

• Vibration Resistance: Highly rigid tool body reduces chatter, producing smooth surface finishes even in high-speed applications.

Applications

• Automotive Manufacturing: Drilling deep oil holes, engine block channels, and hydraulic passages.

• General Engineering & Machinery: High-precision deep-hole drilling for hydraulic valves, manifolds, and structural components.

• Aerospace & Mold Making: Machining heat-resistant alloy components and deep cooling channels in injection molds.

• Suitable Materials: Steel, alloy steel, cast iron, stainless steel, and non-ferrous metals
