PCD standard inserts DP (11° clearance angle) type 55°
The PCD Standard Insert DP Type (11° Clearance Angle, 55°) is a precision turning insert designed for fine finishing and high-speed machining of non-ferrous and abrasive materials. Its polycrystalline diamond (PCD) cutting edge provides unmatched wear resistance, while the 11° positive clearance and 55° rhombic geometry ensure smooth cutting action, low cutting forces, and exceptional surface finishes.

Product Details
Key Features
·
PCD Cutting Edge – Ultra-hard diamond layer (~8,000–10,000 HV) for superior wear
resistance and extended tool life.
·
55° Rhombic Shape – Two sharp cutting edges per insert for precision profiling and
finishing.
·
11° Clearance Angle – Positive rake reduces cutting forces, ideal for light to medium
finishing operations.
·
Excellent Surface Finish – Achieves mirror-like Ra ≤0.2 µm on aluminum, brass,
copper, and composite materials.
·
High-Speed Capability – Stable at cutting speeds up to 1200 m/min, perfect for
modern CNC lathes.
·
Low Built-Up Edge – Diamond resists material adhesion for consistent accuracy.
·
Rigid Carbide/Steel Substrate – Provides dimensional stability and vibration damping.
·
Coolant Optional – Performs dry or with MQL, reducing coolant costs.
·
Environmentally Efficient – Long tool life and fewer tool changes cut down on
waste.
·
Precision Ground Edges – Maintains tight tolerances for aerospace, automotive,
and electronics applications.

Frequently Asked Questions
1.
Which materials are best suited for DP PCD inserts?
Aluminum alloys, copper, brass, magnesium, carbon-fiber composites, and other
non-ferrous materials.
2.
Why use an 11° clearance angle?
The positive rake lowers cutting forces and heat generation, ideal for fine
finishing.
3.
How many usable edges are available?
Two per insert—index to the opposite corner when one edge wears.
4.
Can it machine steel or cast iron?
No. PCD reacts with ferrous metals at high temperatures; choose CBN inserts
instead.
5.
What cutting parameters are recommended?
Cutting speed 500–1200 m/min, feed 0.05–0.2 mm/rev, depth of cut up to 1 mm
(finish passes).
6.
Is coolant necessary?
Not required; many applications run dry or with minimum-quantity lubrication.
7.
Can the insert be re-sharpened or re-tipped?
Yes, professional diamond grinding services can re-hone or re-tip worn edges.
8.
Which holders fit DP inserts?
Any standard 55° rhombic insert holder with 11° positive rake pocket.
9.
What industries commonly use these inserts?
Automotive, aerospace, electronics, and precision machining of non-ferrous
components.
10.
How should they be stored?
Keep inserts in padded cases to avoid chipping and protect the diamond cutting
edge.
