S16 MWLNL 08 boring bar – for internal turning and bore finishing
Precision boring bar for internal machining
Boring bar S16 MWLNL 08 is a professional boring bar designed for longitudinal turning and bore finishing. The round steel shank with a diameter of ø16 mm and a length of mm ensures cutting stability even at greater tool overhang. The geometry with an entering angle of 95° allows longitudinal turning along the wall with simultaneous light facing.
The combination clamping system (M) ensures maximum clamping rigidity and quick replacement of the WNMG 0804rr insert. 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 boring bar is compatible with WNMG 08 inserts in various carbide grades — select the grade to match the workpiece material.
Typical applications of the S16 MWLNL 08 boring bar
Cutting operations:
| ▸ | Longitudinal boring — enlarging and finishing cylindrical holes |
| ▸ | Bore finishing — negative WNMG geometry provides high cutting edge strength and a smooth surface |
| ▸ | Internal taper turning — bearing seats, internal chamfers, Morse tapers |
| ▸ | Light facing — the 95° angle allows machining the face inside the bore |
| ▸ | CNC production runs — repeatable cutting edge positioning and quick insert replacement in the holder |

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 maximum cutting edge strength and cost efficiency.
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 S16 MWLNL 08 boring bar
Instructions for the combination clamping system (M)
Insert replacement procedure step by step
1 Loosen the clamp
Loosen the clamping screw 2-3 turns
2 Clean the insert seat
Remove chips and debris
3 Install the insert
Fit onto the pin and press down
4 Tighten the clamp
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 4×d (64 mm) without support; use vibration damping for greater overhang |
| ▸ | Cutting edge height — set the cutting edge at spindle center height (±0.05 mm) |
| ▸ | 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 internal coolant (through the spindle) for boring whenever possible. When machining without coolant, reduce cutting parameters by 20–30%. Long tool overhang promotes vibration — if vibration occurs, reduce the depth of cut and increase the feed.
Frequently asked questions — S16 MWLNL 08
The minimum hole diameter is determined by the tool head dimensions — check the D_min parameter in the specification table above.
For a steel shank of Ø16 mm, the recommended maximum overhang without damping is 4×d, or 64 mm. Above this value, vibration may occur — reduce the depth of cut or use a vibration-damped boring bar.
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.
