Carbide burr | flame-shaped | shape H
This carbide burr with a flame-shaped end (ISO code H) is a durable and efficient tool for precision metal machining. Made of tungsten carbide (VHM) and equipped with cross-cut teeth (double cut), it offers long service life and high performance for contouring, deburring, and grinding in tight or hard-to-reach areas. The tool is available in several sizes with a cylindrical shank to suit different machines and applications.
The carbide burr is suitable for machining stainless steel, alloys, and other hard-to-machine metals without wearing down quickly. It is particularly useful in workshop applications where precision and a smooth surface are important. The tool is easily mounted in straight die grinders and provides immediate cutting action with vibration-free operation.
APPLICATION AREA
Suitable for fine machining, profile machining, deburring, and grinding in metal, especially in narrow or deep grooves and areas where other grinding tools struggle to reach. Used in workshop and industrial environments that require precise and durable machining. Several sizes with a cylindrical shank are available for adaptation to the machine and application.

FREQUENTLY ASKED QUESTIONS (FAQ)
What does a flame-shaped geometry (ISO code H) mean and when is it best suited?
The flame-shaped contour (ISO H) has a rounded, tapered tip that resembles a candle flame. This geometry is ideal for:
-
Profile and radius machining: Grinding and deburring in rounded corners, concave surfaces, and chamfers.
-
Hard-to-reach spaces: The tapered shape makes it easy to access angles and narrow cavities.
-
Form and casting machining: Neat smoothing of weld seams and transitions without creating sharp edges.
What is the advantage of double cutting (cross-cut)?
Double cutting means that the cutting edges are crossed in a pattern. It provides three significant technical advantages compared to single-cut burrs:
-
Smaller chips & finer surface: Removes material in very small chips instead of long shavings, resulting in a smoother surface finish.
-
Reduced vibration: Provides better control over the hand tool (such as a straight die grinder) and reduces the risk of grabbing.
-
Better chip and heat evacuation: Reduces buildup on the tool when machining tough materials such as acid-proof and stainless steel.
Why is tungsten carbide (VHM) best suited for machining stainless and acid-proof steel?
Stainless (A2) and acid-proof steel (A4) are work-hardening and generate high frictional heat. Tungsten carbide (Cemented carbide / VHM) has extremely high hardness and heat resistance compared to high-speed steel (HSS). This allows the cutting edges to maintain their sharpness even at high speeds and temperatures, which prevents the tool from becoming dull or seizing.
