CSJ Crown Drill Bit, 4D 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

Short Description

High-performance CSJ Crown Drill Bit featuring a 17.00–17.99 mm 4D drilling diameter range. Engineered with a front-locking body, side-locking drill tip, and internal cooling technology for precision, high-speed, deep-hole indexable drilling.

Product Introduction

The CSJ Crown Drill Bit is a premium industrial-grade indexable insert drill engineered for demanding high-speed, deep-hole machining. Featuring an advanced front-locking body coupled with a side-locking drill tip, this tool ensures maximum rigidity, minimal vibration, and exceptional accuracy even under heavy cutting loads.

Equipped with an integrated internal cooling system, it delivers coolant directly to the cutting edge to optimize chip evacuation and prolong tool life. With a 4D depth capability, it is the ultimate solution for manufacturers seeking to maximize throughput without compromising on surface finish or dimensional tolerance.

Product Parameters

Product Functions & Features

• Internal Cooling for Chip Evacuation: Direct through-tool coolant flow lowers cutting temperatures, prevents chip clogging, and dramatically extends the lifespan of the drill tip.

• Dual-Locking Stability: The combination of a front-locking body and a side-locking tip guarantees zero insert movement, delivering exceptional hole straightness and repeatability.

• High-Speed 4D Deep-Hole Drilling: Effortlessly drills depths up to four times its diameter at high feed rates, reducing cycle times significantly compared to conventional drills.

• Cost-Effective Indexable Design: No need for regrinding. Simply replace the crown drill tip/inserts to maintain peak cutting performance, lowering overall tooling costs.

Application Scenarios

• Heavy Machinery Manufacturing: Ideal for drilling deep, high-precision structural holes in frames, gears, and heavy components.

• Automotive & Aerospace Engineering: Perfect for mass-producing engine blocks, transmission components, and aerospace brackets where tight tolerances ($17.00\text{–}17.99\text{ mm}$) are critical.

• Mold & Die Industry: Efficiently creates deep coolant channels and core holes in tough tool steels.

• Compatible Materials: High-efficiency performance across a wide spectrum of materials, including carbon steel, alloy steel, stainless steel, cast iron, and aluminum alloys.
