C WE HAVE INVESTED RESOURCES IN THE DESIGN AND MANUACTURE O INSERTED CUTTERS indexable Center Drill 2
i-center indexable center drill ( patented ) The world's first indexable center drill. Shortens set up and center drilling time. Increases tool life, which reduces tooling cost. Indexable center insert eatures NC 233: K2 grade carbide insert and TiAlN coated for carbon steel, alloy steel, high alloy steel, cast iron and Al, Al-alloy, Cu, Cu-alloy. 2 cutting edges, high performance for center drilling. Metric sizes: DIN 332 A+B, DIN 332 R, Ø1~Ø1 mm Inch sizes: ANSI (BS) #2 ~1 Special inserts are available on request Applications Coolant Big chip flow area. High pressure coolant can be supplied through center directly to tip of center drill insert. 3 indexable Center Drill
The i-center is a trademark of Nine9, the developer of the first indexable center drill. Offering an indexable insert system for the 1st time, Nine9 s i-center patented design provides the benefit of solid carbide cutting parameters while delivering - High Speed, High eed Rate High Performance speed and feed can be achieved due to the specially ground insert and rigid holder design. or example, for drilling Ø3.15mm hole on alloy steel, running at 6 r.p.m. and feed rate 6 mm/min. (.1mm/rev.) Easy Tool Length Setting The axial position accuracy of the insert is.5 mm(.2 ). It is not necessary to reset the tool length when changing insert or cutting edge. Excellent Repeatability The insert is securely positioned by two locating pins and clamped by one insert screw at the center. The positioning repeatability of the insert is within.2 mm(.8 ) in radial direction, thus ensuring conformity to any national standard 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. Universal and Easily itted with Any Available Shank The tool holder is made of high alloy steel, hardened and ground to h6 tolerances with a flat. It s easy for both stationary and rotating tools. 2 cutting flutes indexable Center Drill 4

C C Center Height Adjusting Sleeve with coolant hole Principle Designed for adjusting Center Height of center drills, NC spot drills, reamers and taps on the CNC lathes. The main body is made from two sleeves. The inner sleeve is to hold and lock the cutting tool. Its center is inclined to the outer sleeve. When the inner sleeve is pushed or pulled, the cutting tool s center height is adjusted to lower or higher position.
