PWLNR 25X25 M08 turning tool – for longitudinal turning with light facing
25×25 mm indexable turning tool for a WNMG insert
Turning tool PWLNR 25X25 M08 is an indexable turning tool designed for external turning on conventional and CNC lathes. The shank, with a cross section of 25×25 mm and a length of 150 mm, provides the rigidity required for industrial machining. The geometry with an entering angle of 95° allows turning along the wall with simultaneous light facing.
In the lever clamping system (P), the lever presses the WNMG 0804rr insert against the pocket walls through its hole. The negative geometry of the 80° trigon insert with 6 cutting edges is suitable for roughing and medium machining, providing high cutting edge strength and cost efficiency through its double-sided design. The tool is compatible with WNMG 08 inserts in various carbide grades — select the grade to match the workpiece material.

Typical applications of the PWLNR 25X25 M08 turning tool
Cutting operations:
| ▸ | Longitudinal turning — the 95° angle provides stable cutting along the workpiece axis with light facing |
| ▸ | Roughing and medium machining of steel and cast iron — negative WNMG geometry provides a stronger cutting edge and 2× as many edges |
| ▸ | Machining shafts and bushings — a general-purpose tool for external turning of rotational parts |
| ▸ | Taper turning — machining tapered surfaces on CNC and conventional lathes |
| ▸ | CNC production runs — quick insert replacement and repeatable positioning |

Compatible WNMG 0804rr insert
WNMG 0804rr
The cutting insert is not included in the set — must be purchased separately. WNMG insert. Negative geometry means that the insert is double-sided and has 6 cutting edges, providing a stronger cutting edge and twice as many edges as a single-sided insert.
Select the insert grade to match the workpiece material: P (structural steels), M (stainless steel), K (cast iron), N (aluminum). You can find compatible inserts in the section "Related products" below.
Insert installation and replacement for the PWLNR 25X25 M08 turning tool
Instructions for lever clamping (P)
Insert replacement procedure step by step
1 Loosen the lever
Unscrew the lever screw 2-3 turns
2 Clean the insert seat
Remove chips and debris
3 Install the insert
Fit the hole over the pin
4 Tighten the lever
Torque 0.8–1.5 Nm
Important: Do not exceed the recommended tightening torque — this may damage the thread in the seat or crack the insert.
Checks before starting work:
| ▸ | Tool overhang — do not exceed 1.5× the shank height without support |
| ▸ | Cutting edge height — set the cutting edge at spindle centerline height |
| ▸ | Insert seat condition — check that the contact surface is not damaged or worn |
| ▸ | Secure clamping — the insert must have no play in the seat |
| ▸ | Indexing — when an edge wears out, rotate the insert to a fresh edge (6 edges in total) |
Note: Use coolant during machining — it extends insert life and improves surface finish. When machining without coolant, reduce the cutting parameters by 20–30%.
Frequently asked questions — PWLNR 25X25 M08
This tool accepts inserts WNMG 0804rr in any carbide grade. Select the grade to match the workpiece material: P (steels), M (stainless steel), K (cast iron), N (aluminum). You can find compatible inserts in the "Related products" section below.
The entering angle of 95° provides stable longitudinal turning with light facing. A typical angle for general-purpose machining on CNC and conventional lathes.
The WNMG insert has negative geometry (clearance angle 0°), which means it is double-sided with 6 cutting edges. When one edge wears out, rotate or flip the insert to use the next edge — this significantly reduces tooling cost per part.
