16 mm reduced-shank HSS DIN 338 metal drill bit – versatile industrial tool
Standardized HSS drill with a diameter of 16 mm, compliant with DIN 338 with a reduced shank combines quality standards with practical usability. The 13 mm diameter shank allows immediate use in standard drill chucks. DIN 338 defines clear specifications for tool geometry and material.
Technical properties of the 16 mm Varel drill according to DIN 338
- Compliance with DIN 338 – 118° point angle and helix geometry according to the standard
- Shank reduced to 13 mm – direct compatibility with drill presses and magnetic drilling machines without adapters
- 118° cutting edge geometry – parameter specified by DIN 338, proven in various industrial applications
- Precision-ground finish – improves edge sharpness and drilled hole accuracy
- HSS material according to DIN 338 specifications – high-speed steel with properties that ensure a long service life
- Quality guaranteed by Varel – manufacturer of cutting tools for industry
DIN 338 ensures consistent specifications across different manufacturers, providing users with predictable results. The design with a shank reduced to 13 mm meets the needs of workshops equipped with standard machines, eliminating the cost of specialized adapters.
Frequently asked questions
The 118° point angle is the standard value specified by DIN 338, optimal for most structural steels. This geometric parameter provides a balance between cutting efficiency and cutting edge durability.
We recommend coolant emulsions or metalworking oils, depending on the material. Proper cooling is essential for maintaining drill sharpness and producing high-quality holes.
For lower-strength structural steels, we suggest 270-370 rpm; for harder grades, 230-310 rpm. These values are based on machining principles for HSS and the given diameter.
