1. The use of Heat Shrink Tooling allows for greater speeds and feeds, better finishes, increased tool life,
and increased productivity due to its High Speed Machining capability and simplicity of use.
2. Simple and fast to use. The total time elapsed to remove one cutting tool and insert another is less
than 10 seconds.Constructed with double tempered Tool Steel for exceptional durability and cycle life.
No mechanical clamping devices are used. With proper use, tool holder’s life should exceed that of
standard End Mill holders.
3. Chip load distributed evenly along cutting edge of tool which results in longer tool life. Tool is gripped
360°, along the entire length of the bore resulting in an evenly distributed clamping force and increased
concentricity.
4. Improved balance design with no moving pieces. Low centrifugal Forces due to low holder mass.
Technical Specifications
• TIR: 0.0001" or better
• Kilowood Toolholder is balanced to G2.5 25,000 RPM on a HAIMER Tool Dynamic Balancing System
from Germany. Balanced tool holder minimizes the centrifugal forces which minimize the stress on spindle
bearing, minimize vibration and maximize the cutting tool's life cycle and greatly improve surface finish.
• Taper ground to AT3 or better accuracy standard for maximum contact with spindle. All of Kilowood
toolholder use STOTZ Air/Electronic Gaging for production and finish inspection.
• Made from alloy steel hardened to 52-56 HRC
• Increase cutting tool life, removal rate and workpiece accuracy
• Works on all CAT40 Machines
• Coolant through capability by removing the internal set screw
• Standard holders have 4.5° angle nose for compatibility with most heat shrink machines.
• Excellent surface finish, extreme gripping and ideal for high-speed applications
Applications
Step Milling High-speed finish milling Drilling
Reaming Tapping Chamfering
Why Buy A Balanced Toolholder?
Tool holders make the all-important connection between the cutting tool and the spindle. With the hard-earned
money you invest in cutting tools, it only makes sense to do everything possible to increase tool life. One of the
easiest ways to do this is to use balanced toolholders.
Toolholders can greatly influence the difference in tool life.
The use of a balanced toolholder can result in increased accuracy and repeatability due to less vibration and
chatter. They can help to improve spindle bearing life and improve surface finish. They can save your time by
allowing for faster speed and feed rates. All of these benefits mean that you save time and money.
Why Are They Balanced To G2.5 or G6.3?
Quite simply, this means that the toolholder balance is consistent with the spindle as recommended by
International Standards Organization (ISO) standards. Balancing to the spindle is the best of class
balanced tool holder. KILOWOOD is international Quality AT3 Class balanced V-flange toolholder
manufactured to the highest degree of technical excellence.
