Description
TUNGSTEN STEEL – The burrs are made of top quality tungsten steel (solid carbide). The hardness is more than HRA 85, which means they can last much longer than high speed steel burrs or grinding wheel..3MM SHANK – The 3mm straight shank ,3mm cutting diameter can be held by any rotary tool with three-jaw chuck for accurate centering. A good choice of DIY carving, engraving, and polishing..DOUBT CUT DESIGN – The groove lines of the head are crossed. The cross pattern is faster to remove chips than a single cut can be, and it is not easy to be blocked when grinding and engraving. That's why it's more suitable for an object whose density is relatively low, such as wooden, plastic, and aluminum..20PC SET - The set includes 20 rotary burrs of different head patterns,include: ball, cone, rounded cylinder, flat top cylinder. Each pattern is suitable for a specific scene to be used. The set allows you to select the perfect burr for every job..STORAGE CASE - The 20 burrs are well packed in a compact transparent case. When your job is done, you can place your burrs back into the case for storage and future use.
