CSJ Crown Drill Bit, 4D Drill Diameter Range 13.00-13.99, 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 (4D, Ø13.00-13.99mm) is a high-performance indexable insert drill engineered for high-speed, deep-hole operations. Featuring an innovative front-locking body and an advanced internal cooling system, it delivers maximum stability, superior chip evacuation, and exceptional tool life in demanding manufacturing environments.

Product Introduction

Designed for precision and built for endurance, the CSJ Crown Drill Bit is a game-changer for deep-hole drilling applications. This 4D indexable drill utilizes a secure side-locking drill tip mechanism combined with a rigid front-locking body, minimizing vibration even during high-feed, high-speed machining.

By eliminating the need to remove the entire tool body during insert changes, it significantly reduces machine downtime and boosts shop-floor productivity. Whether you are tackling tough alloys or high-volume steel components, the CSJ Crown Drill delivers unparalleled accuracy and hole quality.

Product Parameters

Product Functions (Key Features)

• Internal Cooling System: Dual internal coolant channels deliver high-pressure fluid directly to the cutting edge, rapidly lowering temperatures and ensuring efficient chip evacuation.

• Front-Locking Stability: The robust front-locking design prevents insert deflection, ensuring excellent hole straightness and strict dimensional tolerance control.

• Quick-Change Side-Locking Tip: Allows for rapid replacement of the carbide crown tip directly inside the machine, drastically slashing setup times.

• Optimized Chip Flutes: Specifically shaped 4D flutes quickly channel chips away from the hole, preventing chip clogging and tool breakage.

Application Scenarios

The CSJ Crown Drill Bit is highly versatile and optimized for heavy-duty industrial manufacturing, including:

• Automotive Manufacturing: High-precision drilling of engine blocks, crankshafts, and transmission components.

• Aerospace & Defense: Machining deep holes in heat-resistant superalloys, titanium, and aircraft structural components.

• Mold & Die Industry: Deep-hole drilling for mold bases, ejector pin holes, and water cooling lines.

• General Engineering: Ideal for heavy machinery fabrication, wind power components, and structural steel processing.

• Compatible Materials: Structural steel, alloy steel, stainless steel, cast iron, and high-temperature alloys.
