$403.0000

Product Overview

The CSJ Crown Drill Bit (7D Series) is a high-performance, indexable deep-hole drilling solution engineered for maximum efficiency and precision. Featuring an advanced front-locking body mechanism and internal cooling channels, this tool ensures exceptional stability and superior chip evacuation during high-speed operations. Designed for heavy-duty industrial manufacturing, it accommodates replaceable side-locking drill tips, drastically reducing downtime and tooling costs.

Key Features

7D Deep-Hole Capability: Effortlessly handles drilling depths up to 7 times the drill diameter.
Front-Locking Design: Ensures rigid insert clamping, minimizing vibration and maximizing hole accuracy at high speeds.
Internal Through-Coolant: Delivers high-pressure coolant directly to the cutting edge to reduce thermal stress and clear chips instantly.
Indexable & Cost-Effective: Features a side-locking replaceable drill tip system, allowing quick tip replacement without removing the drill body.
