VBMT Inserts Manufacturer & Supplier in China
Source standard and custom VBMT positive turning inserts for precision profiling, finishing, and small-part machining with verified 5° clearance geometry.
What Is a VBMT Insert?
A VBMT insert is an ISO 35° diamond, 5°-clearance, M-tolerance, positive single-sided turning insert with a fixing hole and chipbreaking geometry. Its acute point and positive flank support access and lower cutting force in finishing and profiling, with two principal corners available from one face.

VBMT Insert Applications
VBMT inserts are selected where their verified shape, clearance, and holder access match the cutting path and setup.
Precision Profiling
Fine contours that require access from the 35° point.
Small-Part Turning
Low-force machining of smaller diameters when holder and setup rigidity are limited.
External Finishing
Light cuts with radius, edge sharpness, and feed selected for surface finish.
Back Turning
Reverse-direction profile cuts only where the holder, hand, and toolpath permit them.
Slender Components
Reduced-force turning where deflection control remains essential.
VBMT Insert FAQ
Why must VBMT not be labeled as 0° clearance?
The ISO second letter B denotes a 5° clearance angle; a 0° negative insert would use N in that position.
How should a sharp VBMT edge be protected in handling?
Use individual pockets, avoid loose contact between inserts, keep seats clean, and do not touch unused corners with hard tools.
What controls minimum achievable profile radius?
The insert nose radius, holder geometry, machine interpolation, workpiece deflection, stock, and required finish all contribute.
Can VBMT be used in a DNMG holder?
No substitution should be made from shape alone; clearance style, thickness, hole, seat, clamp, and holder designation must match.
Which data are needed for a finish complaint?
Provide measured roughness, feed, speed, depth, radius, material, runout, rigidity, wear image, and whether built-up edge is present.
Can a polished VBMT geometry be sourced?
A polished sharp-edge option can be reviewed for suitable non-ferrous materials after alloy, finish, coolant, and volume are confirmed.
