Carbide Burr Bits Set for Dremel Rotary Tool Accessories

Sworker 10 PCS Tungsten Carbide Burr Designed in Germany and manufactured in Germany and the USA using 6-axis CNC technology, this set of 10 PCS 3mm shank carbide burrs is made in China. The package includes the 10 burrs, a 20-slot plastic clamshell box (with 10 empty slots for additional storage), a buckle hook plastic box, a beech base, and a detailed manual.

The burrs feature a variety of head shapes, including End-Cut Cylindrical, Ball-Nosed Cylindrical, Ball, Oval, Ball-Nosed Tree, Tree, Flame, Cone, and Inverted Cone. The head diameter is 6mm, with a length ranging from 5 to 12mm. The heads have 14 spiral flutes and are made of tungsten carbide with a hardness of HRA90. The 3mm shank is 38mm long and made of 40Cr material. The overall length is 43 to 50mm.

These burrs are designed for a wide range of applications, including carving, engraving, sculpting, deburring, contouring, chamfering, milling, cleaning, porting, cutting, grinding, polishing, elongating, and tooling. They can handle a variety of materials, such as hard wood, balsa, wax, soapstone, slate, marble, granite, concrete, steel, hardened steel, weld-seams, stainless steel, brass, copper, bronze, aluminum, cast-iron, cast-steel, cobalt, nickel, titanium, zinc, earthenware, terracotta, porcelain, fiberglass, plastic, rubber, and fiber-reinforced plastics.

The manual provides important safety instructions, such as wearing appropriate personal protective equipment and using the proper feed direction and rotation speed for different materials. It also advises on minimum clamping depth, handling vibrations, and applying the right amount of pressure. The manual recommends using a grinding oil for soft materials like aluminum and water as a lubricant for grinding glass.

The burrs are designed for use with straight, angle die grinders, and robotic tools, as well as drills and drill presses. They are compatible with 3mm or 1/8" (3.175mm) collets and nuts, as well as 3-jaw chucks, though the latter are not optimal. High-speed rotary tools, such as Dremel, Milwaukee, and other electric or air-powered tools, are recommended for the best performance.

This set of tungsten carbide burrs is versatile, sharp, aggressive, well-balanced, and durable, making them suitable for tight spaces and detailed work where grinding discs may not be as effective. The included manual and the protective storage system ensure a convenient and organized use of these high-quality burrs.
