Short Description

The CSJ Crown Drill Bit (5D, Ø8.00–8.49mm) is a high-performance indexable insert drill engineered for high-speed, deep-hole drilling. Featuring an advanced front-locking body and internal cooling channels, it ensures maximum stability, efficient chip evacuation, and a prolonged tool life when handling demanding machining tasks.

Product Overview

Designed for precision and high efficiency, the CSJ Crown Drill Bit bridges the gap between solid carbide drills and indexable drills. Its innovative side-locking crown/drill tip system allows for quick and secure inserts replacement directly on the machine, minimizing downtime. With a 5D drilling depth capacity and a specialized front-locking mechanism, this tool delivers exceptional rigidity, reduces vibration, and guarantees excellent hole accuracy and surface finish even at high cutting speeds.

Key Functions & Benefits

High-Speed Deep-Hole Machining: Easily handles 5D depth ratios while maintaining high rotational speeds and feed rates without compromising accuracy.
Internal Cooling Technology: Dual through-coolant holes deliver coolant directly to the cutting edge, drastically reducing thermal stress and ensuring seamless chip evacuation.
Superior Rigidity: The robust front-locking design tightens the connection between the body and the crown tip, preventing deflection and vibration.
Cost-Efficient Maintenance: The indexable side-locking tip allows operators to replace only the worn crown rather than the entire drill body, significantly lowering tooling costs.

Target Applications

This versatile drilling tool is optimized for heavy-duty manufacturing and precision engineering across various industries:

Automotive Industry: Precision drilling of engine blocks, crankshafts, and transmission components.
Aerospace & Defense: Machining high-strength alloys and structural components requiring tight tolerances.
Mold & Die Making: Efficient deep-hole drilling for cooling lines in complex mold bases.
General Engineering: Ideal for processing a wide range of materials, including carbon steel, alloy steel, cast iron, and stainless steel on CNC machining centers and lathes.
