PCD standard inserts CN (0° clearance angle) type 80°
Product Details • Product Name: PCD Standard Insert – CN Type • Geometry / Shape: Rhombic (80° included angle, ISO CN style) • Clearance (Relief) Angle: 0° (negative rake insert) • Cutting Edge: Polycrystalline Diamond (PCD) tipped • Common Sizes: CN..1204, CN..1606, CN..1907 (custom sizes available) • Edge Prep: Sharp or honed depending on application • Holder Compatibility: Fits all standard ISO CN tool holders • Typical PCD Grades: 1300/1500 series or equivalent Description The PCD Standard Insert CN Type is a negative-rake 80° rhombic insert designed for heavy-duty roughing, interrupted cuts, and finishing of non-ferrous and abrasive materials. Its 0° clearance angle provides maximum edge strength, making it ideal for rigid setups and high metal-removal rates. The PCD cutting edge delivers exceptional hardness and thermal conductivity, ensuring superior surface finish and long service life in demanding applications such as automotive, aerospace, and composite machining.

Frequently Asked Questions
Q1. What materials can CN-type PCD
inserts machine?
A: Non-ferrous metals (aluminum, brass, copper, magnesium), carbon-fiber
composites, high-silicon alloys, and graphite.
Q2. Can they be used on hardened
steels?
A: No. PCD reacts with iron at high temperature. Use PCBN inserts for hardened
steels.
Q3. What cutting speeds are
recommended?
A: Typically 800–3,000 m/min for aluminum; adjust based on rigidity and
workpiece material.
Q4. Do I need coolant?
A: Not required. Dry machining works well; a light mist or air blast helps chip
removal.
Q5. How does tool life compare to
carbide?
A: PCD inserts generally last 5–10 times longer than premium carbide.
Q6. Are these inserts
re-sharpenable?
A: Yes. Specialized service centers can regrind or re-tip PCD edges.
Q7. What feed rates are typical?
A: For finishing, 0.05–0.3 mm/rev; higher feeds possible for roughing non-ferrous
alloys.
Q8. Do they require special tool
holders?
A: No, they fit standard ISO CN tool holders.
Q9. How should I store PCD inserts?
A: In their protective cases, in a dry, vibration-free environment to avoid
chipping.
Q10. Are they suitable for abrasive
composites like CFRP or GFRP?
A: Yes, PCD is ideal for carbon- and glass-fiber composites, minimizing
delamination and wear.
