● World’s first indexable center drill.
● Shortens set up and center drilling time.
● Increases tool life and reduces tooling costs.
♦ High Speed, High Feed Rate
• The special ground insert and rigid holder design facilitate high performance speed and feed rates. For example, drilling alloy steel at 6000 rpm and feed rate of 600 mm/min. (0.1 mm/rev.)
♦ Excellent Repeatability
• The positioning repeatability of the insert is within 0.02 mm (.0008”) in radial direction, thus ensuring conformity to any national standards.
♦ Easy Tool Length Setting
• The axial position accuracy of the insert is 0.05 mm (.002”). It is not necessary to reset the tool length when changing or cutting edge.
♦ Extended Tool Life
• Coolant can be supplied through the center of the holder to increase performance and extend tool life.
• Insert geometry, grades and coating process are specifically engineered for centering applications.
♦ Inserts:
• Three type of forms for your option - DIN332 Form R, DIN332 Form A+B and ANSI 60 degree.
• K20F grade, TiAlN coated, for carbon steel, alloy steel, high alloy steel and cast iron.
• 2 cutting flutes design same as carbide center drill for high performance speed and feed rate.
• Each insert has 2 cutting edges.
♦ Special forms are possible
