Dormer Deep hole twist drills DIN 1869 / 2 Type W Nominal Ø 11.5 mm HSS-E Series 2

The deep hole spiral drill DIN 1869 / 2 Type W with a nominal diameter of 11.5 mm made of HSS-E from Dormer’s series 2 is a specialized tool designed for extremely deep drilling. With an overall length of 365 mm and a cutting length of 250 mm, this drill meets the requirements of the DIN 1869 / 2 standard. The drill is made from cobalt-based HSS-E, which provides it with high heat hardness resistance. The parabolic flutes and 130° point angle ensure efficient chip removal and allow for drilling up to 20xD without prior centering. This drill is ideal for machining various types of steel, including high-strength steel, gray cast iron, and ductile iron, and is particularly suitable for applications where high thermal stresses occur. The strong spiral and the special point grinding contribute to the efficiency and durability of the tool.

• Parabolic flutes (PFX) for high efficiency in deep drilling
• Suitable for drilling up to 20xD without centering
• Highly spiraled with a strongly twisted spiral
• Excellent heat hardness resistance for demanding applications
• Versatile for various types of steel and cast materials.
