Diamond Tipped Single Point

Basic Application Guidelines

For CBN and PCD Tipped Tools and Inserts

Applications PCD CBN
Hard Cast Iron No Yes
Soft Cast Iron No Yes
Hardened Steel No Yes
Super Alloys No Yes
Abrasive Nonmetallic Yes No
Nonferrous Materials Yes No

Cubic Boron Nitride (CBN)

CBN is excellent for the continuous cutting of a wide range of hardened steels, powdered metals, cast irons and super alloys. CBN tipped product are precision ground with hones for matching to sub-micron finishes with maximum tool life. CBN tipped tools and inserts can take the place of grinding.

Polycrystalline Boron Nitride (PCD)

PCD is excellent for continuous cutting of a wide range of non-ferrous and non-metal materials. The products are precision ground for machining to sub-micron finishes with maximum tool life. PCD tipped tools and inserts allow for higher cutting speeds with longer tool life.

Guidelines for CBN

(Ideal for hard ferrous metal -45 Rc plus)

Depth of cut should not exceed 30% of CBN tip length.
Do not use coolant as this could cause thermal cracking.
Do not stop the machine with the tool in cut - this will result in tool breakage.
Make sure the machine and setup is rigid and solid; chatter will cause chipping.
Tool height when boring should be slightly above center; tool deflection will put the tool on center.
Do not contact the tool to a hard surface prior to the machining process - this will cause chipping.

Guidelines for PCD

(Ideal for non-ferrous materials)

Higher speeds minimize tool buildup.
Depth of cut should not exceed 70% of PCD tip length.
Use of coolant will reduce heat and improve surface finish.
Do not stop the machine with the tool in cut - this will result in tool breakage.
Make sure the machine and setup is rigid and solid; chatter will cause chipping.
Tool height when boring should be slightly above center; tool deflection will put the tool on center.
Do not contact the tool to a hard surface prior to the machining process - this will cause chipping.
