8 Pcs 1/4 Carbide Burr Set for Metal Rotary Tool Attachment - Compatible with Milwaukee Dewalt

Product Overview: Sworker 8 PCS Tungsten Carbide Burr Set

Introducing the Sworker 8 PCS Tungsten Carbide Burr Set, expertly designed in Germany and manufactured using advanced 6-Axis CNC technology from both Germany and the USA, with production established in China. This comprehensive package includes an 8-piece set of 1/4-inch shank carbide burrs, conveniently housed in a durable eight-slot inner plastic clamshell box. Additionally, it features a sturdy outer plastic buckle hook clamshell box, a beech base for secure storage, and a user-friendly manual.

Specifications:

The set contains various head shapes including Ball, Cylinder, Ball-Nosed-Cylinder, and Ball-Nosed-Tree. Each head comes in different diameters (6mm, 10mm, 12mm) and lengths (5mm, 9mm, 16mm, 20mm, 25mm). The spiral flutes range in quantity from 15 to 24, while the burrs are made from high-quality Tungsten Carbide with a hardness rating of HRA90. Each burr has a shank diameter of 1/4" (6.35mm) and length of 45mm, constructed from robust 40Cr material. The overall length of the burrs falls between 50mm to 70mm.

Performance:

These double-cut burrs operate at a maximum rotation speed of 60,000 RPM and are designed for right-hand (clockwise) rotation. For optimal results, the feed direction is generally counter-rotational or executed with a swinging motion, allowing for a fine finish. The recommended tools for optimal drive include straight and angle die grinders, while average tools include drills and drill presses. Both air and electric rotary tools are compatible with the set, and for the best grip, 1/4" (6.35mm) collet and nut are preferred, although 3-jaw chucks are also suitable.

Material Compatibility:

This versatile set is perfect for a wide range of materials including hardwood, balsa, wax, stone, slate, marble, granite, concrete, various metals (such as steel, stainless steel, brass, copper, bronze, aluminum, cast iron, cast steel, cobalt, nickel, titanium, and zinc), as well as ceramics like earthenware, terracotta, and porcelain. The burrs can be utilized for applications such as carving, engraving, sculpting, deburring, contouring, milling, cleaning, porting, cutting, grinding, and polishing.

Usage Guidelines:

1. Always wear protective gear, including ear, eye, and face protection, as well as safety gloves.
2. For rough tasks, operate the burrs in a counter-rotational manner across the workpiece.
3. To achieve fine finishes, move the tool in the direction of rotation.
4. Ensure a minimum clamping depth of two-thirds of the shank length to avoid complications; lower the speed if clamping less.
5. In cases of rough running, vibration, or increased sparks, replace with a new burr.
6. Apply minimal pressure, allowing the speed to do the work, especially for smaller burrs that require higher speeds.
7. Use grinding oil for soft materials like aluminum to prevent clogging and water as lubricant for grinding glass.
8. To elongate holes, grip the tool securely with two hands and employ a swinging motion to avoid chatter and ensure safety.
9. Avoid excessive impact loads, which can damage parts or cause breakage; limit the burr’s penetration to one-third of its periphery.
10. For optimal drive recommendations: use 1/8" shanks for tools between 75-300W and for 1/4" shanks, use over 300W, with 500W+ being advantageous for coarse cuts.

Conclusion:

The Sworker Tungsten Carbide Burr Set is a must-have for any tool enthusiast or professional, offering a versatile range of shapes for various applications in carving and cutting across multiple materials. The set promises durability, sharpness, and efficiency, providing a superior alternative to traditional grinding options. With a detailed manual included, you'll have all the guidance you need to achieve precise and clean cuts with reduced noise and vibrations.
