CSJ Crown Drill Bit,10D Drill Diameter Range 11.50-11.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

High-performance CSJ Crown Drill Bit engineered for high-speed, deep-hole drilling applications (10D depth). Featuring a front-locking body with an internal cooling system, it delivers exceptional chip evacuation, high precision, and extended tool life for hole diameters ranging from 11.50mm to 11.99mm.

Product Overview

The CSJ Crown Drill Bit is a state-of-the-art indexable deep-hole drilling solution designed for modern CNC machining. Built with a rigid front-locking interface and a side-locking drill tip structure, it ensures seamless tip replacement directly on the machine without losing positioning accuracy.

Equipped with through-tool internal coolant channels, coolant is delivered directly to the cutting zone. This effectively lowers cutting temperatures, reduces thermal wear, and ensures smooth, continuous chip evacuation during demanding 10D deep-hole operations.

Product Specifications

Key Functions & Features

• Deep-Hole Precision (10D): Capable of drilling up to 10 times the tool diameter in a single pass without pecking, maintaining strict hole straightness and dimensional accuracy.

• Efficient Internal Cooling: Pressurized internal coolant washes chips out through the flutes instantly, preventing chip jamming and thermal stress on the cutting edge.

• Quick-Change Front-Locking Structure: Fast side-locking mechanism allows rapid head changes directly inside the machine, drastically cutting setup time and tool costs.

• High-Speed Machining Stability: Heavy-duty body design absorbs cutting vibrations during high-feed, high-speed continuous operations.

Applications & Industries

• Target Materials: Carbon steel, alloy steel, stainless steel, cast iron, structural steel, and high-temperature alloys.

• Industrial Sector: Automotive manufacturing, aerospace components, heavy equipment, mold & die making, oil & gas hardware, and general precision engineering.

• Machining Equipment: Suitable for CNC machining centers, CNC lathes, horizontal boring machines, and specialized deep-hole drilling equipment.
