Wysokowydajne wiertła monolityczne z węglika spiekanego

Wiertła do głębokich otworów Beyond™ SC • Obróbka stali i materiałów nieżelaznych • Wewnętrzne doprowadzanie chłodziwa

Features and benefits
  • HP solid carbide deep-hole drills with through coolant for steel, cast iron, stainless steel, high-temperature alloys, and non-ferrous materials.

  • Application-specific SC drill for drilling holes up to 40 x D up to 4x faster than conventional HSS and gun drills.

  • Broadest diameter range on the market from .0938–.6299″ (2,383–16mm).

  • KMH-point geometry is available as a semi-standard, especially for crankshaft applications.

  • KN25™ uncoated grade (B27_HPS) with highly polished surface ensures superior chip evacuation and prevent built-up edge in aluminum and high-temp alloys, even when low-pressure coolant or MQL is applied.
