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 Feed
Rate
High Performance speed
and feed can be achieved
due to the specially ground
inser t and rigid holder
design. For example, for
drilling Ø3.15mm hole on
alloy steel, running at 6000
r.p.m. and feed rate 600
mm/min. (0.1mm/rev.)
Easy Tool Length Setting

the holder to increase
performance and extend
tool life. Insert geometry,
grades and coating process
are specifically engineered
for centering applications.
Universal and Easily Fitted
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
stationar y and rotating
tools.
