Product description
Indexable holder for external grooving and parting. MGEHR is right-hand and MGEHL left-hand. Insert width, seat geometry and maximum working depth depend on the selected variant.
60Si2Mn spring steel design.
Application
For external grooves and parting on a lathe. The selected insert defines groove width. Match working depth to the particular holder geometry rather than to shank size alone.

Dimensions and working range
Working depth is not fixed for a whole shank size. It can differ with the same shank, another insert width or another R/L design. The T value in a variant label refers to that design working depth.

| Shank | According to the selected variant |
| Cutting width | According to insert and seat |
| Working depth T | According to the specific R/L design |
| Overall length | According to the specific holder |
Clamping and components
Seat the insert and clamp it with the screw-actuated upper jaw. Screw and key sizes belong to a specific design; one accessory set does not apply to every holder size.

Matching the lathe toolholding arrangement
Before selecting, check toolholding dimensions, working clearance, insert width and the required operation. Select the current design in the product selector. An insert designation identifies the seat rather than replacing holder dimensions.
FAQ
Do all sizes use the same insert?
No. Insert system and size depend on the particular seat.
Are holder dimensions enough to select the tool?
No. Also check insert width, insert system and the working range of the selected design.
Where is the design selected?
Use the product variant selector.
Does shank size alone determine working depth?
No. Depth also depends on insert width and the geometry of the specific R/L design.
