- 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.
- 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.
Drill bit for use in alloyed and unalloyed steels up to 900N/mm² tensile strength, sheet metal and thin wall profile material, where accurate and clean drilling is required.
- 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.
