TCT Hard Line 40 Uncoated Annular Cutter - 20.1315 Series (Karnasch)

(KARNASCH-20.1315)

Starting at £45.19 £37.66

The 20.1315 series TCT Annular cutters are tungsten carbide tipped and are ideal for high performance drilling through holes in Steel, Stainless Steel, Grey Cast Iron, Aluminium, Copper, Brass, Tin, Plastics and Exotics (such as inconel and hastelloy). Annular cutters (also known as core drills) are an extremely efficient method of drilling through holes because they only cut the periphery of the hole, therefore much less material removal is required compared to conventional drill bits. Please note these are not suitable for blind holes.

Features & Benefits
  • TCT (Tungsten Carbide Tipped) Annular Cutter/Core Drill
  • 40mm/1-1/2" max drill depth
  • For high performance drilling in Steel, Stainless Steel, Grey Cast Iron, Aluminium, Copper, Brass, Tin, Plastics and Exotics
  • Ideal for drilling through holes, not suitable for blind holes
  • Annular cutters/core drills are extremely efficient because they only cut the periphery of the hole (less material removal is required)
  • Holes produced by annular cutters are more finished, precise and accurate due to the unique geometry
  • These can easily be used on lower RPM machones such as magnetic drills (mag drills) or light duty drilling machines
