What is a flame burr used for?
The flame profile is particularly useful for:
- Shaping and blending curved or profiled surfaces
- Working around internal radii and rounded corners
- Smoothing and refining fillet welds
- Blending transitions between adjoining surfaces
- Deburring curved edges and irregular openings
- Working inside confined or difficult-to-reach contours
- Controlled shaping with both the rounded tip and fuller sides
Double-cut flutes
The crossed double-cut flute pattern divides the removed material into smaller chips, providing controlled cutting and efficient material removal on harder metals.
Suitable materials
- Mild and hardened steels
- Stainless steel
- Cast iron and cast steel
- Nickel-based alloys
- Titanium and other hard metals
For aluminium, copper, brass and other softer non-ferrous metals, an open-fluted burr specifically designed for non-ferrous materials may resist clogging more effectively.
Will it fit my rotary tool?
This burr has a 2.35mm (3/32") shank. It can be used in Dremel and similar rotary tools fitted with a suitable 2.35mm collet or adjustable chuck. It is also compatible with many micromotors, pendant motors and flexible shaft systems that accept 2.35mm accessories.
If using a Dremel, an adjustable Dremel Multi-Chuck is usually the most convenient option.
How to use
- Secure the shank firmly and as deeply as practical inside the collet or chuck.
- Start the rotary tool before bringing the burr into contact with the workpiece.
- Use light, controlled movements and allow the flutes to cut.
- Keep the burr moving smoothly when blending curved surfaces.
- Do not force, lever or twist the burr sideways.
- Wear suitable eye protection.
Tungsten carbide is extremely hard but can be brittle. Excessive pressure, impacts, chatter or sideways leverage may damage the cutting head or shank.
