CSJ Crown Drill Bit, 4D Drill Diameter Range 34.00-34.99, 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 (4D) designed for high-speed, stable deep-hole drilling. Featuring a front-locking design with an integrated internal cooling system, this indexable side-locking drill body delivers exceptional chip evacuation, high precision, and an extended tool life for a Ø34.00mm–Ø34.99mm diameter range.

Product Introduction

The CSJ Crown Drill Bit represents the next generation of indexable deep-hole drilling technology. Engineered with a 4D drilling depth capacity, it utilizes a secure front-locking mechanism coupled with a side-locking drill tip to ensure maximum stability and rigidity under heavy cutting loads.

What sets this drill apart is its internal cooling (thru-coolant) system, which delivers high-pressure coolant directly to the cutting edge. This drastically lowers temperatures, reduces friction, and forces chips out of deep holes effortlessly. Ideal for high-speed operations, it allows manufacturers to achieve superior surface finishes while minimizing downtime through quick insert replacements.

Product Parameters

Key Product Functions & Benefits

• High-Speed Deep Hole Drilling (4D): Enables stable drilling up to four times the tool’s diameter without compromising structural integrity.

• Advanced Internal Cooling: Delivers coolant directly to the cutting zone, suppressing heat buildup, extending tool life, and preventing chip clogging.

• Front-Locking Secure Design: The side-locking drill tip and front-locking body eliminate vibration, ensuring high centering accuracy and strict hole tolerances.

• Indexable Efficiency: Allows quick crown/insert changes directly on the machine, reducing setup time and lowering cost-per-hole significantly.
