for ST.
Wang

ST. Wang is a cutting tools manufacturer whose product scope includes drill bits and indexable drill solutions. The company’s drill-related lineup is positioned for precision drilling needs where durability and repeatable performance are required across varied materials and machining conditions.

For general carbide drill use, the brand’s technical content emphasizes carbide drills as a high-hardness, wear-resistant tool choice that helps maintain sharp cutting edges over extended use, supporting higher machining precision and longer tool life.

When drilling becomes heat- and chip-sensitive, internal coolant carbide drills are highlighted as an effective approach, delivering coolant through internal channels to reduce heat at the cutting edge and help flush chips out of the hole.

Note: Performance may vary depending on cutting conditions such as speed, feed rate, coolant pressure/flow, machine rigidity, runout, and workholding.

Coolant Hole Carbide Drills Series

Overview

ST. Wang’s catalogue index explicitly references a “Coolant Hole Carbide Drills Series & Carbide Drills Series,” aligning with the company’s published explanation of internal coolant carbide drills. Internal coolant drills are described as tools with internal coolant channels that deliver coolant directly to the cutting area to remove heat efficiently and improve chip evacuation during drilling.

This approach is particularly effective for drilling operations where heat buildup and chip packing can reduce tool life or cause instability, supporting more consistent machining and fewer process interruptions.

Compatible Materials

• Materials and drilling conditions that benefit from improved chip evacuation and heat control
• Deeper-hole drilling or higher-load drilling where internal coolant flow improves stability

Lineup

• Coolant hole carbide drill series is listed in ST. Wang’s EDM/catalogue index (specific models and dimensions depend on catalog selection)
