Fyrimunir

• Tip Top tip (from dia. 3.0 mm)
• Precise centring - the drill almost never runs off centre and it is even possible to perform angled spot drilling
• Rapid drilling progress - multiple cutting edges in use at the same time
• Circular holes even in sheet metal work
• Simple drilling - minimal energy expenditure required
• Does not snag in the material - makes drilling out existing holes effortless
• Latest generation - HSSX base material
• Maximum flexibility and heat strengthening in one tool
• Even more universal - more material types can be processed
• Surface
• The multifunctional steam oxide (Fe2 O4) coating is an adhesive oxide coating with a thickness of 0.010 mm and offers the following advantages:
• Improved adhesion of cooling lubricant on the tool surface prevents built-up edges and cold welds.
• Improves chip evacuation from the cutting edge, reduces heat development in the critical zone.
• Increased surface hardness for improved wear resistance.

Góð ráð

• At 13.5 mm and above, the shank is reduced to 12.7 mm.
