CSJ Crown Drill Bit, 5D Drill Diameter Range 17.00-17.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Product Short Description

The CSJ Crown Drill Bit (5D, Ø17.00–17.99mm) is a premium indexable insert drill engineered for high-speed, deep-hole machining. Featuring an innovative front-locking body with an advanced internal cooling system and a secure side-locking drill tip, it delivers exceptional stability, rapid chip evacuation, and superior hole accuracy in demanding industrial applications.

Product Introduction

Revolutionize your deep-hole drilling operations with the CSJ Crown Drill Bit. Designed for maximum efficiency and durability, this 5D indexable drill bridges the gap between solid carbide performance and indexable versatility.

At its core is a robust front-locking body paired with a side-locking drill tip mechanism, ensuring zero slippage and maximum rigidity under high torque. To combat heat and prolong tool life during deep 5D penetrations, the drill features state-of-the-art internal cooling channels that deliver coolant directly to the cutting edge. This eliminates chip packing and ensures a flawless surface finish every time.

Product Parameters (Specifications)

Product Functions & Features

• High-Speed Deep-Hole Penetration: Optimized 5D flute geometry allows for fast, continuous drilling without the need for frequent pecking cycles.

• Advanced Internal Cooling: Dual internal coolant holes force chips out out of the hole instantly, drastically reducing heat friction and preventing thermal cracking of the insert.

• Dual-Locking Stability: The combination of a front-locking body and side-locking tip provides superior structural rigidity, minimizing vibration and runout even at high RPMs.

• Cost-Efficient Indexable Design: Instead of replacing or regrinding the entire drill body, you only replace the crown insert tip, cutting tooling costs significantly.

Application Applications (Scenarios)

The CSJ Crown Drill Bit is ideal for heavy-duty metalworking sectors requiring precise, deep-hole drilling:

• Automotive Manufacturing: Drilling engine blocks, crankshafts, and heavy powertrain components.

• Aerospace & Defense: Machining high-strength alloys and structural components.

• Mold & Die Making: Creating deep water/coolant lines in injection molds with tight tolerance requirements.

• General Engineering & Energy: Ideal for tube sheets, heat exchangers, and heavy machinery fabrication.

• Compatible Materials: Highly effective in Carbon Steel, Alloy Steel, Stainless Steel, Cast Iron, and exotic materials like Titanium or Nickel-based alloys (depending on the insert grade selected).
