DCMT070204 DX120 ISO turning insert (PCD) — rhombic 55°, Tungaloy

A DCMT070204 DX120 indexable turning insert engineered for high-speed turning of aluminium, non-ferrous metals and abrasive non-metals, offering long tool life and consistent chip control.

• PCD grade DX120 for high cutting speeds
• Rhombic 55° geometry for versatile turning
• Single-sided chipbreaker for stable chip control
• ISO-compatible insert with hole and countersink

Faster aluminium machining through PCD technology

The DX120 grade is a polycrystalline diamond (PCD) cutting material bonded on a carbide substrate, designed specifically for non-ferrous and abrasive non-metals. This structure permits significantly higher cutting speeds and markedly longer tool life compared with conventional carbide inserts when turning aluminium alloys. PCD provides an extremely hard, wear-resistant cutting edge that reduces flank wear and preserves geometry over longer production runs, which translates into fewer interruptions for tool changes and more predictable cycle times.

Reliable chip control and consistent surface finish

A combination of the single-sided chipbreaker and the 55° rhombic shape ensures controlled chip formation and evacuation in a wide range of turning operations. The controlled chip flow lowers the risk of built-up edge and improves surface quality on delicate materials, delivering repeatable results shift after shift. The modest corner radius (0.4 mm) helps achieve a balance between strength and fine surface finish, making the insert suitable for finishing and semi-finishing passes in stable set-ups.

Clear selection and holder compatibility to reduce downtime

The insert conforms to ISO dimensions and features a cylindrical hole with a one-sided countersink (40°–60°), ensuring mechanical compatibility with standard ISO turning holders and clamping sets. Because fit depends on form, clearance angle, tolerance class, fastening method, nominal size and thickness, selecting the correct holder-clamp combination is crucial; matching these parameters avoids seating errors and vibration, which otherwise compromise tool life and component quality. The simple system composition—insert, appropriate external holder or boring bar, shim/clamp set and replacement screws—facilitates rapid assembly and straightforward inventory planning.

FAQ

What materials are best suited for this insert?
The DCMT070204 DX120 turning insert is optimised for aluminium, non-ferrous metals and abrasive non-metals; the PCD cutting material and carbide substrate provide excellent wear resistance for these workpiece types.

How does the DX120 grade differ from conventional carbide grades?
DX120 is a polycrystalline diamond grade, offering much higher hardness and abrasion resistance than typical carbide grades, which results in higher cutting speeds and extended service life for the insert.

Is the insert compatible with standard ISO holders?
Yes, the insert follows ISO dimensions and includes a cylindrical hole with a one-side countersink; mechanical compatibility depends on matching form, relief angle, tolerance class, fastening and thickness to the chosen holder.

What is the purpose of the single-sided chipbreaker?
The one-sided chipbreaker on this rhombic insert promotes reliable chip control and predictable chip segmentation, which aids surface finish and reduces the risk of built-up edge during high-speed turning.

Which SKU should be ordered for this item?
Order using the manufacturer article number 6822158 or manufacturer SKU TUN6822158 to ensure the correct DCMT070204 DX120 Tungaloy insert is supplied.
