Alpen | Drill Bit HSS Cobalt 3.5mm DIN338 RN

HSSCobaltJobber Drill Bit

Size: 3.5 x 70/39mm

Range of application

• 5% cobalt-alloyed jobber drills with high heat resistance for drilling steels with tensile strength over 800N/mm, especially suitable for high alloyed steels, bearing steels, hot/cold-rolled steel. Ideal for stainless steel

Strengths

• Self-centering, due to a special point shape
• Drilling even with the highest thermal stress up to 600
• Fast, due to special drill grinding fast drilling progress and up to 50% less feed pressure required
• Tensile strength over 800N/mm
• Especially suitable for high alloyed steels, bearing-steels, hot/cold-rolled steel
• Ideal for stainless steel
• High heat-resistance
• Highly accurate centering
