L9860 Description

Short technical summary and product information.

The ST L9860 is a high-performance carbide drill designed for semiconductor production equipment components. It features a 4mm diameter and a 12mm through hole depth, making it suitable for precise drilling applications.

 

The drill is constructed from 304 SS material and is coated with AlCrTiN REVO-D, which suppresses wear and chipping, leading to a longer tool life of 900 holes compared to conventional drills. It operates at a rotation speed of 1,600 rpm and a feed rate of 160 mm/min, utilizing water-soluble coolant.

 

This drill is designed for use with vertical M/C BT30 machines. Its robust construction and advanced coating contribute to stable wear and the elimination of chipping, allowing for regrinding and extending its usability. The Aqua REVO drill stub design focuses on tool life extension and cost reduction for customers.
