Description

Product Description:

A high-performance solid carbide twist drill designed for ultra-deep-hole machining up to 20 × D. Compliant with ISO standards, this drill features internal cooling channels to deliver high-pressure coolant directly to the cutting edges, ensuring efficient chip evacuation, reduced heat, and superior hole quality. Optimized for high-speed cutting, it provides excellent stability, precision, and long tool life across a range of materials including steels, stainless steels, aluminum, and alloys.

Features:

  • 20 × D drilling depth → ideal for ultra-deep-hole precision machining.

  • Solid carbide construction → high rigidity, excellent wear resistance, and long service life.

  • ISO standard design → ensures universal compatibility and process reliability.

  • Internal cooling channels → deliver coolant directly to the cutting edges for improved cooling and chip evacuation.

  • Optimized point angle and cutting edges → reduce thrust force and enhance centering and precision.

  • Advanced flute geometry → promotes smooth chip evacuation, especially in deep holes.

  • High-speed cutting capability → supports modern CNC machining of steels, cast irons, aluminum, and alloys.
