14.5 mm reduced-shank HSS DIN 338 metal drill bit – tool conforming to DIN 338
Standardized HSS drill with a diameter of 14.5 mm meeting DIN 338 requirements with a reduced shank provides repeatable machining parameters. The shank, reduced to a diameter of 13 mm, allows direct mounting in commonly used industrial tool holders. DIN 338 defines clear geometry and material requirements.
Technical data for the Varel Ø14.5 mm DIN 338 drill
- Compliance with DIN 338 – 118° point angle and flute geometry conforming to the industrial standard
- Shank reduced to 13 mm – direct compatibility with drill presses and magnetic drilling machines without adapter sleeves
- 118° cutting angle – a universal value conforming to DIN 338, effective across a wide range of materials
- Precision-ground finish – ensures high-quality cutting edges and dimensional accuracy of the holes
- HSS steel in accordance with DIN 338 – material with properties that ensure adequate hardness and heat resistance
- Certified Varel quality – manufacturer of cutting tools for industry
DIN 338 provides the basis for tool interchangeability and predictable performance across different manufacturers. The shank reduced to 13 mm meets the needs of facilities equipped with standard drilling machines, eliminating the cost of additional adapters.
Frequently asked questions
DIN 338 precisely defines all key tool parameters: dimensions, angles, geometry and material requirements. As a result, drills from different manufacturers that conform to this standard are interchangeable and deliver predictable results.
Cooling is highly recommended for diameters close to 15 mm to achieve optimal machining results. Using emulsion or oil extends tool life and improves the quality of the drilled holes.
For mild structural steels, the optimal range is 300-410 rpm, and for higher-strength steels, 255-340 rpm. Correct spindle speeds ensure efficient cutting and long drill life.
