• Higher cutting speed: 1.5 - 2 times faster
• Pecks (Q) up to 1 x d. Maximum pecks of ½ x d are common to this day, with the average being ¼ x d or less
• Higher feed rate: 20 % – 30 % higher

*Comparison based on drilling tools available in the market for stainless, acid-resistant and heat-resistant steel and machining parameters recommended by manufacturers.

• Special tungsten carbide: high fracture toughness and thermal shock resistance
• High-performance coating: lower friction coefficient guarantees less heat buildup, protects from cutting edge breakage and wear; low adhesion to material prevents bonding; resistant to thermal loads (high hot hardness)
• Additional advantage with the type IK, the drill with through-tool cooling: the coolant jet is always aimed on the drill tip; continuous, substantial cooling on the drill tip; cooling independent of protruding edges; continuous flushing of chips from the flutes

• No drill or chip jamming
  • Short chips: special polished cutting edge
  • Quick chip removal: very smooth helical flutes; digressive helical flutes, divided into two areas: a chip breakage area with a steep helix angle and a chip removal area with a flat helix angle
• Defined and certified drilling process with specifications for cutting speed and feed rate as well as pecking steps
• Heat development under control:
  • Low torque (low friction) thanks to innovative drill tip geometry
  • Carbide sensitive to thermal shock
  • Heat-resistant coating

*Comparison based on drilling tools available in the market for stainless, acid-resistant and heat-resistant steel and machining parameters recommended by manufacturers.

• Sturdy solid tungsten carbide shaft supports stable and non-oscillating drilling
• Best drill bit for stainless steel with good centering properties due to polished tip section with small transverse cutting
• High degree of position and drilling accuracy (diameter tolerance): diameter precision of the drill 0/+0.004 mm (0”/+ .0002”)
• Good alignment accuracy (no deviation) and hole roundness

• Shorter machining time: up to 10 times faster
• Longer tool life: up to 15 times longer
• Higher degree of process reliability

• CrazyDrill SST-Inox IK / IN 8 x d: because of the high degree of self-centering capability, on regular and straight surfaces the use of a centering or pilot hole is not necessary. On irregular respectively rough or inclined surfaces or for high-precision position accuracy: CrazyDrill Pilot SST-Inox as pilot drill, CrazyDrill Twicenter as center drill, CrazyDrill Crosspilot as pilot drill for inclined surfaces
• CrazyDrill SST-Inox IK / IN 12 x d: as perfect preparation for high-precision position accuracy: CrazyDrill Pilot SST-Inox as pilot drill, CrazyDrill Twicenter as center drill and CrazyDrill Crosspilot as pilot drill for inclined surfaces
• Drill size diameter range: drill 0.2 mm – 2.0 mm (.008” - .079”, fractional inches available)
• Increments: every 0.05 mm (.002”)
