Product Introduction

The VBMT insert can equip with multiple chip breakers to deal with finishing, semi-finishing, and roughing works.

We also develop various applicable coatings to enhance productivity.

Key Features of VBGT Inserts

Shape:
- V: Rhombic (diamond-shaped) with a 35° included angle. This sharp angle offers strength at the cutting tip and allows for versatility.
Clearance Angle:
- B: 5° relief angle (clearance angle). This ensures the insert doesn’t rub on the workpiece.
Other Features
- Positive Rake Angle: The cutting face slopes slightly forward from the cutting edge, providing smoother cutting and lower cutting forces, suitable for softer materials or low-power machines.
- Chipbreakers: VBMt inserts often feature chipbreaker geometries to control chip formation and flow.
- Coatings: They can be coated with materials like TiN, AlTiN, etc., to improve wear resistance and tool life.

VBMT insert Specification

Understanding the VBMT Code

Here’s what the letters and numbers in the VBMt designation mean:

V: 35° rhombic shape
B: 5° relief angle (clearance angle)
M: Tolerance class (indicates precision of the size)
T: Can indicate hole type and chipbreaker design (varies by manufacturer)
Numbers:
- Usually the first two numbers represent the inscribed circle (size of the diamond) in sixteenths of an inch (or directly in millimeters for ISO codes).
- The third number represents thickness in sixteenths of an inch.
- The last number often indicates the nose radius (smaller means sharper).
