    Featured in National Hardwood Magazine

    Carbide insert wear apparent in woodcutting is created by a large percentage from chemical corrosion with the carbide’s cobalt binder (glue). This allows the hard tungsten particles to leach out thus creating a dull cutting edge.

    How does Corrosion Happen in Wood?
    During woodcutting resins, tannins, sap, moisture and also various glues present in wood today create an acidic environment that chemically attacks the carbide surface, leaching the cobalt binder away. This chemical leaching process is enhanced with higher cutting temperatures.

    What is Chrome Submicron Binder KCR08?
    CERATIZIT have created a revolutionary new corrosion resistant Chrome binder grade called KCR08. Submicron chrome replaces cobalt as the primary binder.

    Submicron Chrome is Resistant to Corrosion Resulting in up to Two Times the Cutting Life.
    KCR08 also incorporates a submicron grain structure, this means the tungsten particles (tungsten is what makes carbide hard) are much smaller than conventional carbide, so when the tungsten does finally release from the binder it has a much smaller impact to the cutting edge as smaller pieces of tungsten are being removed.

    Three Major Benefits of Chrome KCR08:

    1. Greater Corrosion Resistance
    Corrosion to conventional carbide inserts can be caused during tool fabrication from grinding lubricants and also during wood cutting from chemicals/resins/glue and air moisture result in premature tool wear. This also reduces the component cut surface quality.

    Chrome KCR08 grade minimizes these risks during tool manufacturing as well as during the operation of the finished tool. Your process becomes more stable; machining times are optimized, with an overall performance improvement of the finished tool of up to two times.

    2. Higher Performance Potential
    For wood working applications, KCR08’s optimized binder system improves the ratio of hardness vs. fracture / impact toughness. Compared to conventional grades, KCR08 grade at same hardness is tougher and therefore more resistant to impact. The cutting edge has greater stability and will resist chipping longer. This will allow the tool producer to use harder grades than previously used conventional grades due to the improved toughness and chipping resistance. The results being better tool life time at improved cut quality.

    3. Cost Effective
    Prices for KCR-grades are at a comparable level to those of our current conventional grades. Higher process reliability and increased cutting performance of up to two times will enable process cost savings and provide you with an enhanced price-performance ratio.

    Submicron grain size in conjunction with Chrome is a very important part of what makes KCR08 perform the way it does. Submicron means the size of Tungsten particles (grain size) in KCR08 are much smaller than Micron. When tungsten particles do finally release from the cutting edge through wear there are much smaller tungsten particles being removed from the knife compared to larger chunks of Tungsten with Micrograin.
