DIAMOND & CBN ROTARY TOOLS
DIAMOND & CBN ROTARY TOOLS Info

Diprofil Rotary Diamond and CBN Tools are made from carefully selected
quality diamonds and Cubic Boron Nitride, precisely bonded to obtain the
best physical properties for added strength and resistance to wear�
Electroplated Diamond pins and wheels are excellent for general grinding
applications in hard materials such as carbide, hardened steel and ceram-
ics� They are normally used without cooling agent but in stationary applica-
tions, and when grinding in thin glass cooling is often required� Maximum
temperature for Diamonds is 800 °C�
Electroplated cylindrical CBN pins are excellent for general grinding appli-
cations 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�

Recommended speeds
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�
