ISO 3 R/L NNBc-d DIN 4978 bent side turning knife for machining steel and cast iron

Our lathe knife has been manufactured from the highest quality materials, which guarantees its durability and resistance to extreme working conditions. The ISO 3 R/L NNBc-d DIN 4978 standard and carefully selected cutting inserts make our tool perfect for machining steel and cast iron, ensuring precise cutting and finishing of workpieces.

A curved side turning knife is a type of cutting tool used in lathes for metal and woodworking. It is characterized by a curved shape of the blade, which allows cutting the material from the side. Thanks to this design, the tool can be used for turning external and internal shapes, profiling, grooving and other machining operations.

The curved side lathe knife allows you to efficiently remove material from your workpiece and produce precise details and finishes. It is a particularly useful tool when machining parts with complex shapes, where traditional turning knives may have limitations due to material access.

In the metalworking and woodworking industries, curved side lathe knives are commonly used to produce all kinds of parts, from machine parts to structural components. Their versatility and precision machining capabilities make them an indispensable tool in many manufacturing plants and craft workshops.

The main features of our curved side turning knife:

1. Exceptional strength and durability due to high quality materials.
2. Precision cutting and forming of steel and cast iron while minimizing material waste.
3. Curved design for easier access to the workpiece.
4. Resistance to extreme operating conditions, which translates into reliability in all conditions.

Choose our ISO 3 R/L NNBc-d DIN 4978 bent side turning knife and experience excellent quality and productivity in your industrial operations. With a professional tool from FENES S.A., you will achieve excellent results in steel and cast iron machining, increasing the efficiency and quality of your production.

DIN 4978 is a German technical standard that applies to turning tools, including turning knives. It specifies requirements for the geometry, tolerances and markings of turning knives, which is important for their proper use in metal and woodworking on lathes.

DIN 4978 covers various types of turning knives, including side knives, longitudinal knives, flat knives and so on. It also specifies their dimensions, shapes and other important technical parameters that affect the efficiency and quality of machining.

With DIN 4978, users can rest assured that lathe knives meet certain quality standards and are properly adapted to lathe operation, helping to improve safety and the efficiency of material processing.

ISO 3 R/L refers to a standard for cutting tool geometry, or in this case, a turning knife, which is in accordance with ISO standards.

ISO 3 R/L in brief:

- "ISO" means that the standard conforms to the standards of the International Organization for Standardization (ISO), which guarantees a certain level of standardization and quality.

- "3" refers to a specific type of cutting tool geometry that is defined within the ISO standard. In this case, "3" refers to the specific shape, profile or other features of a lathe knife geometry.

- "R/L" refers to the direction of the turning knife blade. "R" means that the blade is right-handed, while "L" is left-handed.

ISO 3 R/L is the standard designation for a lathe knife, which specifies its geometry and possibly the direction of the blade, according to International Organization for Standardization standards.
