Diprofil Diamond & CBN Machine Files

Diprofil Diamond and CBN Machine Files are made from carefully selected quality diamonds and Cubic Boron Nitride (CBN), precisely bonded to obtain the best physical properties for added strength and resistance to wear. Uniquely designed for use with profilers and particularly adapted for dies, molds, and most other shop requirements. Diprofil Diamond and CBN Machine Files can be used at faster speeds and higher temperatures than may other tools.

Electroplated Diamond files are excellent for use on carbide, hardened steel, glass, ceramics and other similar materials. They are normally used without cooling agents, but in stationary applications, and when grinding in thin glass cooling is often required. Maximum temperature for Diamonds is 800° C. Diamond files are Medium D151 grit.

Electroplated CBN files are excellent for general grinding applications in hardened steel. They are normally used without cooling agent but in stationary applications cooling is often required. Maximum temperature for CBN is 1200° C. CBN files are Medium D100 grit.

Files are 50mm / 2" OAL.

Recommended speeds (see Specifications for more information)

Recommend speed for dry cutting:
Diamond: 10 – 20 m/s
CBN: 15 – 30 m/s

Recommend speed for wet cutting:
Diamond: 15 – 30 m/s
CBN: 20 – 45 m/s 

Cooling: Cooling normally enhances the lifetime of the tools. In addition it also generates a better surface. The risk for damage on thin or sharp edges of the grinding tool is reduced when using coolant. Cooling is performed with an emulsion or grinding oil. For diamond tools an Emulsion is specially recommended and for CBN tools a mineral oil is preferable.
