SVVBN 16x16 16 turning tool – for longitudinal turning and copy turning
16×16 mm indexable turning tool for a VBMT insert
Turning tool SVVBN 16x16 16 is an indexable turning tool designed for external turning on conventional and CNC lathes. The shank with a 16×16 mm cross section and a length of 100 mm provides the rigidity required for industrial machining. The geometry with a 72.5° entering angle enables longitudinal turning and profiling in both feed directions, with good access to the machined surface.
In the central screw clamping system (S), the screw secures the VBMT 1604rr insert through its hole, so only one screw needs to be loosened for replacement. The positive geometry of the 35° diamond insert with 2 cutting edges is well suited to finishing, providing low cutting forces and a smooth machined surface. The turning tool is compatible with VBMT 16 inserts in various carbide grades — select the grade to match the workpiece material.

Typical applications of the SVVBN 16x16 16 turning tool
Cutting operations:
| ▸ | Longitudinal turning with profiling — the 72.5° angle provides good access to the workpiece profile |
| ▸ | Medium machining and finishing of steel and cast iron — positive VBMT geometry ensures low cutting forces |
| ▸ | External taper turning — machining tapered and contoured surfaces |
| ▸ | Profiling and recess machining — the neutral insert orientation allows angled entry into recesses; the entry angle is limited by the insert shape |
| ▸ | CNC production runs — quick insert replacement and repeatability |

Compatible VBMT 1604rr insert
VBMT 1604rr
The cutting insert is not included in the set — must be purchased separately. VBMT insert. Positive geometry means that the insert is single-sided and has 2 cutting edges, providing low cutting forces and good surface quality.
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 SVVBN 16x16 16 turning tool
Instructions for the center screw clamping system (S)
Insert replacement procedure step by step
1 Unscrew the screw
Unscrew the center screw 2-3 turns
2 Clean the insert seat
Remove chips and debris
3 Install the insert
Position in the seat
4 Tighten the screw
Torque 1.0–2.0 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 (2 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 — SVVBN 16x16 16
This tool accepts inserts VBMT 1604rr 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 72.5° entering angle provides good access to the workpiece profile. It is suitable for longitudinal turning, contour profiling, and recess machining.
The VBMT insert has positive geometry (clearance angle 5°), which means it is single-sided with 2 cutting edges. When one edge wears out, rotate the insert to a fresh edge.
