Raw Material Selection

Suitable materials such as tungsten carbide, ceramics, or high-speed steel are selected based on the blade’s application. These materials must offer high hardness and wear resistance.

Powder Metallurgy

Metal powders are mixed in precise ratios, pressed into shape, and then sintered at high temperatures to form blade blanks.

Imported Press Machine Forming

From importing presses to stamp out blade blanks, to subsequent sintering and coating, every step is strictly controlled, all to provide customers with stable and reliable blade solutions

Oswald Insert Pressing

Specifically designed for pressing various types of turning tool blanks, it enhances blade density and lifespan stability, ensuring more consistent batch dimensions and a more reliable cutting process.

Coating Application

The insert undergoes precision grinding and cleaning before being subjected to PVD/CVD vacuum coating, forming a multi-layered hard coating structure that combines high hardness, wear resistance, and stable lifespan.

Edge Preparation & Passivation

The insert edge is finely passivated to remove small dents and burrs, improve the strength and stability of the insert edge, and thus extend the service life of the insert.

Packaging & Shipping

At HNCarbide, every shipment of DCMT carbide inserts is carefully packaged to ensure your tools arrive safely and without damage.
Each DCMT insert is placed in a shock-resistant case, clearly labeled with full DCMT insert specifications, DCMT insert dimensions, and DCMT insert size, then sealed with moisture-proof material before boxing.
Large-volume orders of carbide DCMT inserts are further protected using double-wall cartons or wooden crates to guarantee secure international transport.
We work with trusted logistics partners to ensure your DCMT inserts are delivered quickly and securely by air freight, sea freight, or express courier.

FAQ

What applications are DCMT inserts best suited for?

DCMT inserts are ideal for light finishing, semi-finishing, and profile turning, especially on CNC lathes where low cutting forces are required.
They excel in:

Thin-walled part machining
Small-diameter boring bar operations
Contour turning
High-precision finishing on steel or stainless steel

What does the DCMT insert code represent?

The DCMT designation gives you key details about the insert:

D – 55° diamond shape
C – 7° relief angle
M – Medium tolerance
T – Single-sided insert with chipbreaker

This code helps match the insert to tool holders and cutting conditions.

How do DCMT 11T304 and DCMT 21.51 inserts differ?

DCMT 11T304 (ISO) and DCMT 21.51 (ANSI) differ in:

Sizing system (metric vs inch)
Nose radius
Thickness
Cutting-edge length
Both fit DCMT-style holders but are selected based on machine standard and part tolerance.

Serving 1000+ customers across the globe

“We are an automotive parts manufacturer and have been using your inserts for two years. The wear resistance is excellent, and each insert lasts noticeably longer than our previous brand. The turning surface finish is very stable, which gives us great confidence for mass production orders.”

“As a mold maker, we have very high requirements for tool stability. Your inserts perform reliably in both roughing and finishing. Chipping is rare, size consistency is very good, and we have significantly reduced our tool changes and machine adjustments, which improves our overall machining efficiency.”

“We mainly do subcontract turning work, and in the past, unstable insert life often affected our delivery time. After switching to your inserts, the number of parts we can machine with one insert has increased by more than 30%. The performance from batch to batch is consistent, and together with your fast delivery, our on-time shipment is now much better guaranteed.”
