DN (0° clearance angle) type 55
Product Details • Product Name: PCD Standard Insert – DN Type • Geometry / Shape: 55° rhombic (ISO DN style) • Clearance (Relief) Angle: 0° (negative rake) • Cutting Edge: Polycrystalline Diamond (PCD) tipped • Common Sizes:DN..1103, DN..1504, DN..1906 (custom sizes available) • Edge Preparation: Sharp or honed depending on application • Holder Compatibility: Fits all standard ISO DN-type turning tool holders • Typical PCD Grades: 1300/1500 series or equivalent Description The PCD Standard Insert DN Type is a 55° negative-rake rhombic insert engineered for medium-to-heavy turning, profiling, and finishing of non-ferrous and abrasive materials. Its 0° clearance angle provides maximum edge strength and stability for high-load or interrupted cutting conditions. The PCD-tipped cutting edge ensures exceptional wear resistance and thermal conductivity, making it ideal for automotive, aerospace, electronics, and composite machining where precision and long tool life are critical.

Frequently Asked Questions
Q1. What materials can DN-type PCD
inserts machine?
A: Non-ferrous metals (aluminum, brass, copper, magnesium), carbon-fiber
composites, high-silicon alloys, and graphite.
Q2. Can they machine hardened
steels?
A: No. PCD reacts with iron at high temperatures; use PCBN inserts for hardened
or ferrous steels.
Q3. What cutting speeds are
recommended?
A: Typically 800–3,000 m/min for aluminum; adjust for machine rigidity and work
material.
Q4. Is coolant required?
A: Not necessary. Dry machining works well; an air blast or light mist aids
chip removal.
Q5. How does tool life compare with
carbide inserts?
A: Generally 5–10 times longer under similar cutting conditions.
Q6. Are these inserts
re-sharpenable?
A: Yes, specialized service centers can regrind or re-tip the PCD edge.
Q7. What feed rates are typical?
A: For finishing, 0.05–0.25 mm/rev; higher feeds possible for softer
non-ferrous materials.
Q8. Do they require special tool
holders?
A: No, they fit standard ISO DN tool holders.
Q9. How should PCD inserts be
stored?
A: Keep in 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 excels in carbon- and glass-fiber composites, minimizing
delamination and tool wear.
