Tooling Inserts for Back Turning
High Performing Back Turning Inserts
- Insert design result in low radial forces
- Produces better roundness on the component
- Keeps the desired size longer without adjustment
- Chip is curled before it hits the already finished shoulder
- Good chip-control by curling the chip away from the
surface
|
- Positive cutting rake improves production and tool-life
- Only a narrow parting off insert is required in order to clean
up the non finished cylindrical diameter
- The final diameter is produced only 1 mm from the side of the
insert and tool holder, or away from the guide bushing, resulting in
good stability even when small diameters are produced
- Small distance from the side to end of wiper which makes final diameter. Very suitable for small diameters.

Back Turning Insert Guide
Style C
Style C is used when there is an undercut required. |
Style BT
Style BT inserts has a chamfer on the leading corner that improves the tool-life in harder materials. This insert is suitable when the wear on the style B insert is found in an early stage. |
Style B
Style B is for general use in back turning applications in stainless steel, titanium, nimonic,
hastaloy, high temperature alloys, alloyed steel and other hard
and long chipped materials where good chip control is needed. |
Style VLR
Style VLR is used for backturning when a smooth surface is needed when profiling. It is for example excellent to go in behind the head of a bone screw with. |
Style BP
Style BP is used for sticky materials when there is a chance of an edge build up that can spoil the surface finish or reduce tool-life. |
Style E
Style E is used for fine turning, using high cutting speed and low feed rate. This insert will give the best possible surface finish. By protecting the radius with the chamfer the tool life is extended compared with conventional full radius inserts. |
