14 mm reduced-shank HSS DIN 338 metal drill bit – versatile standardized tool
Proven Ø14 mm HSS drill conforming to DIN 338 with a reduced shank is a tool that combines standardization with practical mounting. The shank, reduced to a diameter of 13 mm, allows direct mounting in typical industrial tool holders. DIN 338 ensures precisely defined tool geometry and material specifications.
Features of the 14 mm Varel drill conforming to DIN 338
- DIN 338 certification – 118° point angle and helix geometry conforming to the industrial standard
- Shank reduced to 13 mm – immediate mounting in stationary and magnetic drilling machines without adapters
- Standard 118° angle – a value specified by DIN 338, suitable for a variety of structural materials
- Precision grinding – ensures highly sharp cutting edges and dimensional accuracy of the drilled holes
- High-speed steel (HSS) according to DIN 338 – material with properties that ensure durability in metal machining
- Varel brand tool – manufacturer of tools conforming to industrial standards
DIN 338 ensures consistent specifications across products from different manufacturers. The shank reduced to 13 mm increases application flexibility across a variety of machines, eliminating the need to purchase specialized adapter sleeves.
Frequently asked questions
DIN 338 standardizes key parameters: point angle, dimensions and material properties. This ensures predictable tool performance and interchangeability of products conforming to this standard.
Cooling is strongly recommended for diameters of 14 mm and above to achieve optimal results. Proper lubrication extends drill life and provides better surface quality and dimensional accuracy of the holes.
For mild structural steels, we recommend a range of 310-420 rpm, and for harder steels, 260-350 rpm. Selecting the correct speed ensures efficient cutting without overheating the tool.
