    Product Description

    The flutes of Karnasch High-Performance countersinkers are always CBN ground. This guarantees: Excellent chip clearance / chatter-free working / scratch-free surface / best centering.

    Tungsten carbide + BLUE-TEC coated, 4 + 5 cuts for difficult machine materials:
    BLUE-TEC coating for a further substantial increase in service life also when machining dry (no/less cooling)
    Diameter 10,4 mm solid carbide
    Diameter 12,4-31,0 mm brazed shank

    Tungsten carbide countersinks Art. 40 3045 comes with cylindrical shank.
    This countersink type is used mostly on CNC machines with shrinking chucks.
    Shrinking chucks works only with cylindrical shank.

    Attention:
    Solid carbide countersinks should be only used on CNC machines.

    3-Flat shank for:
    – Excellent torque transmission
    – No slippage in the drill chuck
    – This results to superior cutting output

    According to the diameter radially-adjusted CBN ground relief.
    Result: The cutting edge is always the highest point of the diameter

    Each diameter receives its own relief angle.
    Result: The cutting edge is also always the highest point.

    CBN deep-ground flutes leads (unlike miled grooves) to significantly smoother and sharper cutting edges. This result is: Higher cutting performance and tool life.

    Axial relief produces by CBN grinding leads to a smooth and low-heat cut.

    USAGE:

    For countersinking in materials:

    • Hardened steel up to 1400 N/mm²
    • Steel up to 60 HRC
    • Acid resistant steel
    • All cast iron types
    • Graphite, carbon- and glass fibre reinforced plastics
    • Exotic materials over 850 N/mm² such as nimonic, inconell, hastelloy
    • Excellent also for hardox 500
