Cubic Boron Nitride (CBN) Inserts • CNGA-MT

Grades

• 
  WBH10C

  A low content CBN grade with a MT-CVD/CVD — TiN-TiCN-Al₂0₃-TiN coating for protection against crater wear. Designed for precision machining of hardened steels (>48 HRC), effectively applied on bearing steels, hot and cold work tool steels, high-speed steels, die steels, case-hardened steels, carburized and nitrided irons, and some hard coatings. Do not use on soft steels.

• 
  WBH10P

  A low content CBN grade with a PVD-TiAlN coating for added wear resistance. Designed for precision machining of hardened steels (>45 HRC); the harder the steel the better. PVD coating offers improved wear resistance and excellent surface finish capability. Effectively applied on bearing steels, hot and cold work tool steels, high-speed steels, die steels, case-hardened steels, carburized and nitrided irons, and some hard coatings.

  H Hardened Materials
• 
  WBH10U

  A low CBN content, CBN tip brazed onto a carbide insert. Designed for precision finishing in smooth cuts on hardened steels (>45 HRC) where optimal surface finish is needed. Use on bearing steel, hot and cold work tool steels, high-speed steels, die steels, case-hardened steels, carburized and nitrided irons, and some hard coatings. Do not apply on soft steel as rapid crater wear will result.

• WBH20P

  H Hardened Materials
• 
  WBH25P

  A PVD-TiAlN coating over a low content, CBN tip brazed onto a carbide insert. Designed for roughing to finishing of hardened steels (>45 HRC). Use on bearing steel, hot and cold work tool steels, high-speed steels, die steels, case-hardened steels, carburized and nitrided irons, and some hard coatings.

  H Hardened Materials
• 
  WBH25U

  A low CBN content, CBN tip brazed onto a carbide insert. Designed for roughing to finishing of hardened steels (>45 HRC) where optimal surface finish is needed. Use in continuous to interrupted cutting of bearing steel, hot and cold work tool steels, high-speed steels, die steels, case-hardened steels, carburized and nitrided irons, and some hard coatings.

  H Hardened Materials
• 
  WBH30P

  A PVD-TiAlN coating over a low content, CBN tip brazed onto a carbide insert. Designed for roughing to finishing in interrupted cuts on hardened steels (>45 HRC). Applied on gray cast iron, chilled irons, high-chrome alloyed steels, high-temp alloys, and sintered powdered metals.

  H Hardened Materials
• 
  WBK45U

  A high CBN content, CBN tip brazed onto a carbide insert. Applied in roughing to finishing of fully pearlitic gray cast iron, chilled irons, high-chrome alloyed steels, sintered powdered metals, and heavy cuts in hardened steels (>45 HRC). Use for finishing chilled and fully pearlitic cast iron. Available in a wide range of insert styles, including positive rake geometries ideally suited for boring applications.
