PCD standard inserts VB (5° clearance angle) type35°
The PCD Standard Insert VB Type (35° tip, 5° clearance) is a precision turning insert designed for high-speed machining of non-ferrous metals and abrasive composites. Its polycrystalline diamond cutting edge provides exceptional hardness and wear resistance, while the 35° VB geometry and 5° relief angle allow smooth, chatter-free cutting for fine surface finishes.

Key
Features
· PCD Cutting Edge – Ultra-hard diamond layer (≈8,000–10,000 HV) for outstanding wear resistance and long tool life.
· 35° VB Geometry – Ideal for fine turning, profiling, and finishing where sharp entry angles improve accuracy.
· 5° Clearance Angle – Reduces friction, ensuring stable chip flow and cooler cutting.
· High Surface Finish – Capable of mirror-like finishes, reducing or eliminating secondary polishing.
· Excellent Dimensional Accuracy – Maintains tight tolerances for precision parts.
· High-Speed Machining Ready – Performs reliably at elevated cutting speeds on modern CNC lathes.
· Stable Carbide/Steel Base – Rigid substrate absorbs vibration for consistent performance.
· Low Built-Up Edge – Diamond edge resists material adhesion, improving consistency on sticky alloys.
· Coolant-Optional – Can run dry or with minimum-quantity lubrication, lowering coolant costs.
· Environmentally Efficient – Long insert life means fewer tool changes and less waste.

Customization product
I’ve been using this product for several months now, and it stands out as one of the best tools for customization in manufacturing. Whether you're working with metal, plastic, or composites, this tool adapts easily to different workflows and materials. Highly recommended for teams looking for precision, efficiency, and customization all in one.
Frequently Asked Questions
1. Which
materials are ideal for this insert?
Non-ferrous metals like aluminum, copper, brass, magnesium, as well as graphite
and fiber-reinforced composites.
2. Why
use a 5° clearance angle?
It minimizes contact between the insert flank and the workpiece, reducing heat
and improving surface finish.
3. What
is the benefit of the 35° VB geometry?
The sharper approach angle allows smooth entry and precise profiling, ideal for
finishing operations.
4. Can
it cut steel or iron?
No. Ferrous materials cause chemical wear of diamond. Use CBN inserts for
ferrous machining.
5. What
cutting speeds are recommended?
Typically 500–1200 m/min for aluminum, adjusted for machine rigidity and part
geometry.
6. Is
coolant required?
Not necessarily. Many users run dry or with mist/MQL to maximize finish and
minimize thermal shock.
7. Can
the insert be re-tipped or re-sharpened?
Yes, professional diamond-grinding services can re-hone PCD edges for extended
life.
8. Which
machines are compatible?
Any CNC or manual lathe that accepts standard VB-style insert holders.
9. What
surface finish can I expect?
With proper setup, finishes as fine as Ra 0.2 µm (mirror-like) are achievable.
10. How
should it be stored?
Keep in a padded insert case to prevent edge chipping; avoid contact with hard
objects.
