Powerful special drill that should ideally be used for titanium base alloys as well as stainless, acid-resistant and heat-resistantaustenitic steels. It is also suitable for high strength steels with low ductility. Under certain conditions, these drills can be used for special alloys such as hastelloy, inconel and nimonic etc. HSSE-Co 8: Heavy-duty high speed steel with 8 % cobalt content.Extremely high ductility and outstanding heat resistance, for drilling holes in high strength materials, austenitic steel, for hot working etc. with a strength of up to 1100 N/mm².The titanium aluminium nitride coating offers high heat and oxidation resistance. Suitable for drilling hard materials without lubrication. Max. application temperature 700 ºC
- The 8% cobalt content maintains a sharper cutting edge and delivers a 4X longer life versus DeWalt Black Oxide bits. - The optimised tip and flute geometry delivers 2X the penetration speed, versus DeWalt Black Oxide bits, removes material faster and reduces heat build up. - The stronger central core delivers 2X the resistance to breakage versus DeWalt Black Oxide drill bits.
- The series of long Bits DIN 340 is best suited for deep and hollow profile holes .; - Manufactured according to DIN 340; - 118 ° split point; - Enamelled silver surface.
- Precision ground twist drill bit for rapid drilling, long life and excellent concentricity. - Manufactured from High Speed Steel to DIN338. - Ground from solid stock right hand cutting, type N flute, precision ground at 118° point angle.
