Set of 5 double-edged rotary files made of tungsten steel, with a 6 mm shank diameter and a 10 mm head diameter, suitable for mold-making and carving grinding machines.

Material: Tungsten steel, shank diameter: 6 mm, drill bit diameter: 10 mm. Easy to use, simple and safe, reliable, it reduces the physical strain of work and improves the working environment. Applications: Machining various metals (including various hardened steels) and non-metals (such as marble, jade, and bone). High quality: High efficiency, precise machining, long service life, and cost-effectiveness. Easy to use, safe, and reliable, it reduces the physical strain of work. Design: Chamfering, rounding, and grooving of mechanical parts. Double cavity design with cross grooves, less prone to clogging, more suitable for machining relatively low-density materials. Product description: Size: Set of 5 rotary files, 50-60 mm. Features: Suitable for machining various metal and non-metal sculptures. Ideal for machining various metals (including various hardened steels) and non-metals (such as marble, jade, etc.), with a machining hardness HRA ≥ 85. Easily machines mold cavities of various shapes with high precision and excellent machining quality. Carbide rotary files are generally used with manual or pneumatic drives (compatible with machine tools). Their service life is 10 times longer than that of high-speed steel tools and 200 times longer than that of small grinding wheels. The rotational speed of the grinding wheel for electric or pneumatic tools is typically 6,000 to 50,000 rpm. Specifications: Cutting edge diameter: 10 mm; Shank diameter: 6 mm; Overall length: 50 to 60 mm. Applications: deburring, texturing and cleaning welds, forging and welding; finishing metal molds; finishing turbine channels; Chamfering, rounding, and grooving of mechanical parts; finishing of internal surfaces of mechanical parts. Contents: - Set of 5 carbide rotary drill bits. Tips: 1. When machining with carbide rotary drill bits using pneumatic or electric tools, the rotation speed is generally between 6,000 and 40,000 rpm, and the tool must be securely clamped. 2. The cutting direction must be from right to left, not reciprocating as with a grinding wheel. Be careful not to apply excessive force (the pressure should generally not exceed 4 kg).
