For the first time, a modular milling system can achieve the similar high performance of the latest generation solid carbide end mills. To deliver groundbreaking joint technology, Duo-Lock™ combines the innovative histories of two leaders in the world of manufacturing—HAIMER and Kennametal.

Duo-Lock™ maximizes a carbide tool’s full potential with productivity gains in both roughing and finishing. It provides high load capacity and rigidity when machining at high metal removal rates. When combined with high-performance cutting tools, Duo-Lock™ provides more than double the metal removal rate in common milling applications.

Available models

HAIMER Tooling Technology Cutting Tool Heads

A variety of the newest milling geometries have become available with the new HAIMER Duo-Lock™ system. The high-precision and extremely stable Duo-Lock™ interface allows the use of the full potential of the milling geometries and achieves the maximum cutting depths at the same time. The cutting tool heads can be changed directly in the machine tool with highest repeatability in the Z-axis; therefore tool measurement is not always necessary.

 

With the additionally available Duo-Lock™ blanks in different length versions you can realize individual milling geometries for special applications.

HAIMER Tooling Technology Extensions

With the new shaft extensions from the Duo-Lock™ series, a universal solution for almost all processing cases is at your disposal:

  • The cost-effective way to process special solutions.
  • Universally applicable due to the different tapered geometries and lengths.
  • With Safe-Lock™ anti-pullout interface to take advantage of long reach and aggressive cuts.
  • High runout accuracy.
HAIMER Tooling Technology Collets

The Duo-Lock collets are perfectly suited for clamping Duo-Lock tools in all established ER collet chucks, driven units and spindles with ER interface.

  • Useable for Duo-Lock milling heads from DL10 – DL25.
  • Compatible with all established ER systems.
  • Optional with Cool-Jet 3 or 6 drillings.
  • Reduced set-up times due to fast and precise tool changes.
  • No need for repeated length adjustments due to the very precise length repeatability with only +/- 10 μm.
  • Process-safe and easy handling.
HAIMER Tooling Technology Monoblock holders

With the Monoblock holders, the famous HAIMER tool holder quality combined with the new Duo-Lock™ technology is available. Duo-Lock™ Monoblock holder for direct clamping of the milling head.

  • Perfectly suitable for milling with short overhang.
  • Smoother running thanks to vibration absorbing geometry, therefore better surface quality and protection of tools, spindles and machines.
  • Increased machining capacity due to higher spindle speeds, higher feed.
  • Shorter processing times, higher machining accuracy, high clamping force.
  • High runout accuracy.
  • High rigidity.

Key Features

  • Superior rigidity of the interface that allows for unique d.o.c. capability of up to 1.5xD and 1xD in full slotting.
  • Geometric parameters of the connection have been optimized and thoroughly tested leading to the most robust modular system ever developed.
  • FEA based design ensures that stress levels in the interface remain below critical values even at elevated loads.
  • The double cone surfaces combined with the third contact area in the back delivers high stiffness and accuracy.
