R420.37 Hydraulic Cylinder Carbide Scraper Inserts are precision-engineered tungsten carbide inserts designed for deep-hole skiving, scraping and roller burnishing of hydraulic cylinder bores. These replaceable carbide inserts are used in cylinder honing, skiving and roller burnishing systems to efficiently remove machining allowance and produce a smooth, accurate inner surface.
The R420.37 series is available in 06T3, 07T3 and 11T3 sizes, with different insert dimensions for different machining requirements. The inserts feature a central mounting hole and a robust cutting geometry designed to provide stable cutting performance during high-load internal machining.
| Model | Thickness | Length | Width | Application |
|---|---|---|---|---|
| R420.37-06T3 | 2.9 mm | 10 mm | 7.5 mm | Hydraulic cylinder skiving |
| R420.37-07T3 | 4.0 mm | 12 mm | 8 mm | Hydraulic cylinder skiving |
| R420.37-11T3 | 4.8 mm | 17 mm | 12 mm | Heavy-duty cylinder machining |
The three sizes provide options for different tool holders, cutting loads and hydraulic cylinder bore machining requirements.
Hydraulic cylinder manufacturing requires accurate internal diameters, good surface finish and efficient material removal. Traditional honing processes can require multiple operations. Skiving and roller burnishing combines high-speed material removal with surface finishing to improve production efficiency.
Our carbide scraper inserts are designed for this type of application.
During machining, the carbide insert removes material from the internal surface of the cylinder bore, while the subsequent roller burnishing operation improves surface finish and dimensional consistency.
Different hydraulic cylinder materials and machining conditions require different carbide grades. We can provide carbide substrates optimized for wear resistance, toughness or a balance of both.
| Carbide Grade | Main Characteristic | Recommended Application |
|---|---|---|
| K10/K20 | High hardness and wear resistance | Finishing & stable cutting |
| K20/K30 | Balanced hardness and toughness | General cylinder machining |
| K30/K40 | Higher toughness | Interrupted/heavy cutting |
| Custom Grade | Application-specific performance | OEM applications |
Coating options can also be selected according to the workpiece material and cutting conditions.
The black and gold inserts shown in the product images can be supplied with different carbide grades and/or surface treatments according to the machining application.
The coating or surface treatment can improve:
Important: The color of the insert should not be used as the sole basis for selecting a grade. Actual carbide composition, coating type and cutting parameters should be confirmed according to the application.
Hydraulic cylinder skiving generates continuous contact between the cutting edge and the workpiece. High-quality tungsten carbide provides the hardness and wear resistance required for extended tool life.
A properly engineered carbide substrate and edge preparation help the insert withstand high cutting loads and reduce premature edge chipping.
Precision grinding ensures consistent insert dimensions and cutting geometry, helping maintain repeatable machining performance.
The 06T3, 07T3 and 11T3 sizes cover different cylinder machining requirements and tool configurations.
We can manufacture hydraulic cylinder scraper inserts according to drawings, samples or specific tool-holder requirements.

Customization can include:
Carbide Grade → Insert Size → Cutting Geometry → Edge Preparation → Coating → Packaging
Customers can provide an existing insert sample, technical drawing or tool-holder information. Our engineers can recommend a suitable carbide grade and geometry for the specific hydraulic cylinder skiving application.
Hydraulic cylinder carbide scraper inserts are replaceable tungsten carbide cutting inserts used for internal bore skiving and scraping of hydraulic cylinders.
R420.37-06T3 is a carbide insert size used in skiving and roller-burnishing tooling for internal machining applications.
The main difference is the insert size. Based on the specifications you provided, their dimensions are 10 × 7.5 × 2.9 mm, 12 × 8 × 4.0 mm and 17 × 12 × 4.8 mm, respectively.
They are primarily associated with skiving/scraping and roller-burnishing processes, rather than conventional honing. The exact compatibility depends on the machine and tool system.
Yes. We can produce customized hydraulic cylinder carbide scraper inserts based on drawings, samples or tool-holder specifications.
