Description
The Somta Stub Drill, part of the HSS-E Parabolic Flute TiAlN Coated (163-X) series, is a high-performance drill designed for serious metalworking. With a 3.7 mm diameter, it combines a compact, rigid stub length with advanced coatings to deliver precise holes in steel, aluminum, and other metals. This tool is built for engineers, machinists, hobbyists, and pros who need dependable accuracy and repeatable results on demanding projects.
Crafted from HSS-E for exceptional hardness and heat resistance, this drill features a TiAlN coating that reduces wear and improves lubricity for longer tool life. The parabolic flute accelerates chip evacuation, keeping heat down and minimizing clogging, while the stub geometry provides outstanding rigidity for clean starts and tight tolerances.
- Rigid stub-length design for precise starts: the shorter, stiffer body minimizes deflection, helping you produce accurate holes with consistent diameter and cleaner finishes—especially useful in hard metals and tight-tolerance work.
- Parabolic flute for efficient chip evacuation: fast chip removal reduces heat buildup and prevents chip packing, enhancing performance in longer drills and busy workpieces.
- TiAlN-coated HSS-E core for wear and heat resistance: the tough coating and substrate tackle higher cutting temperatures, extending tool life and maintaining sharpness through multiple drilling cycles.
This Somta Stub Drill helps you complete projects faster with reliable performance, less rework, and fewer tool changes. Its combination of rigid geometry, efficient chip management, and durable coating translates to consistent hole quality, greater productivity, and confidence in every drilling task.
