Professional extra-long drill 17 mm diameter HSS drill according to DIN 338 with a reduced shank offers high-quality workmanship compliant with European standards. The 13 mm diameter shank allows direct use in typical industrial tool holders. DIN 338 guarantees precise tool geometry and material properties.
Main features of the Ø17 mm Varel drill according to DIN 338
- Compliance with DIN 338 – 118° point angle and helical flute geometry according to the European standard
- Shank reduced to 13 mm – compatibility with stationary and magnetic drilling machines without intermediate adapters
- 118° cutting angle – a universal value specified in DIN 338, effective for most structural steels
- High-quality grinding – increases machining precision and extends tool life
- HSS steel compliant with DIN 338 specifications – a material with properties that ensure adequate hardness and heat resistance
- Certified Varel brand – manufacturer of tools for industry
DIN 338 guarantees consistent specifications across products from different manufacturers. Reducing the shank to 13 mm is a practical response to the requirements of workshops equipped with standard machines, eliminating the need to purchase specialized adapters.
Frequently asked questions
DIN 338 specifies precise requirements for dimensions, point angle, and material properties. This ensures repeatable operating performance and interchangeability of compliant tools from different manufacturers.
Cooling is strongly recommended for diameters above 15 mm to achieve optimal results. Using appropriate cutting fluids extends tool life and improves hole quality.
For mild structural steels, we suggest a range of 255-350 rpm; for higher-strength steels, 215-290 rpm. Selecting the correct speed affects cutting efficiency and drill life.
