CSJ Crown Drill Bit, 4D Drill Diameter Range 32.00-32.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

CSJ Crown Drill Bit (4D, Ø32.00–32.99mm)

Short Description

The CSJ Crown Drill Bit is a high-performance, indexable deep-hole drilling tool designed for high-speed machining. Featuring a 4D drilling depth, a front-locking body, and an advanced internal cooling system, this side-locking drill tip provides exceptional chip evacuation, high precision, and extended tool life in demanding industrial applications.

Product Introduction

Engineered for superior stability and efficiency, the CSJ Crown Drill Bit is the ultimate solution for medium-to-deep hole processing. Its innovative front-locking mechanism ensures quick, secure, and precise insert replacement directly on the machine, minimizing downtime.

Equipped with a 4D length-to-diameter ratio and a robust side-locking drill tip design, it delivers outstanding rigidity and vibration resistance during high-speed operations. The integrated internal cooling (thru-coolant) channels deliver coolant directly to the cutting edge, drastically reducing heat buildup and ensuring flawless chip evacuation even in deep cavities.

Product Parameters

Key Functions & Benefits (Product Action)

• Efficient Chip Evacuation: Internal cooling flushes chips out instantly, preventing chip clogging and tool breakage.

• Rapid Tool Changes: The front-locking system allows operators to change the crown insert quickly without removing the entire tool body from the holder.

• High-Precision Drilling: The side-locking drill tip guarantees rigid clamping, preventing deflection and ensuring excellent hole straightness and surface finish.

• Cost-Effective Maintenance: Instead of replacing the whole drill, you only replace the indexable crown tip, significantly reducing tooling costs.

Application Scenarios

This heavy-duty drill bit is highly versatile and widely used across various heavy manufacturing sectors:

• Automotive Industry: Drilling engine blocks, crankshafts, and heavy-duty chassis components.

• Aerospace & Defense: Precision deep-hole processing of high-strength alloys and structural frames.

• Mold & Die Manufacturing: Drilling deep ejector pin holes and complex water cooling channels in large mold bases.

• Heavy Machinery & Energy: Machining flanges, pressure vessels, wind turbine components, and oil/gas drilling equipment.

• Compatible Materials: Ideal for medium-to-hard steels, alloy steels, stainless steel, cast iron, and high-temperature alloys.
