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 RPMT carbide inserts is carefully packaged to ensure your tools arrive safely and without damage.
Each RPMT insert is placed in a shock-resistant case, clearly labeled with full RPMT insert specifications, RPMT insert dimensions, and RPMT insert size, then sealed with moisture-proof material before boxing.

Large-volume orders of RPMT 1204 inserts or RPMT 1204 carbide inserts are further protected using double-wall cartons or wooden crates to guarantee safe international transport.
We work with trusted logistics partners to ensure your RPMT inserts, including special types such as RPMT 1204 insert 0.473, are delivered quickly and securely by air freight, sea freight, or express courier.

FAQ

An RPMT insert is a round, positive-rake indexable milling insert designed for high-stability operations such as face milling, contour milling, and copy milling.
RPMT inserts provide smooth cutting action, low cutting forces, and excellent chip control—making them ideal for steel, stainless steel, cast iron, and aluminum machining.

The “0.473” typically refers to the maximum depth of cut or insert radius engagement in specific cutter models (equivalent to 0.473 inches).
Some cutter manufacturers use the 0.473 value to indicate how much of the insert radius can be utilized safely during roughing or high-feed milling.
If your cutter specification mentions 0.473, RPMT 1204 is the correct matching insert.

Selection depends on your workpiece:

  • Steel (P) → TiAlN / AlTiN coated RPMT 1204

  • Stainless steel (M) → tougher substrate + heat-resistant coating

  • Cast iron (K) → wear-resistant carbide grade

  • Aluminum and non-ferrous metals (N) → polished, uncoated sharp-edge RPMT 1204 inserts
    Choosing the proper grade improves tool life, reduces vibration, and enhances surface finishing.
