5pcs Rotary Point Burr Set Die Grinder Bit with 12 mm Shank and 6 mm, Carving Tool Tungsten Carbide Steel

Product Information

Carbide burrs, more commonly called die grinder bits, are the attachments used in rotary tools. They’re ideally used for smoothing, grinding, shaping, carving and deburring excess materials in a variety of workpieces. They come in different cutting profiles and shapes to produce different types of cuts. And you can find them in varying sizes. What Are They Made of? Good quality Carbide Burrs are machine ground from a specially chosen grade of carbide. Due to the extreme hardness of the Tungsten Carbide, they can be used on much more demanding jobs than HSS (High-Speed Steel). Use inverted cone shaped tungsten carbide burrs for making v-cuts and rear side chamfering. Carbide Pointed Cone & Carbide Round Nose or Ball Nose Burrs Before the arrival of high precision machines such as CNC milling, EDM Spark Erosion, and EDM Wirecut it was common for the die makers to grind and match the profiles of the mating parts manually. As you know, it is tough to remove material from hardened tool steel with a conventional hand tool such as a file. The die grinder is the best tool for the job since they are small and is to maneuver. Generally, a metal burr is manufactured from either high strength steel (HSS) or Tungsten Carbide. When working with metals only, tungsten carbide burrs are mostly preferable. This is due to their durability in handling several demanding jobs without wear or tear. The HSS burrs, on the other hand, have a reduced tolerance for heat. As a result, high temperature and pressure tend to soften the HSS tool. Compared to HSS, tungsten carbide burrs can last longer.

Long shank carbide burrs can also be found, and these are great for detailed carving in hard-to-reach areas of your work. Head Diameter sizes: Hardness and durability are where your typical die grinder bits run circles around everything else on offer. These things are meant to last and produce consistent results no matter what they’re used on. This will range from commonly-used metals such as stainless steel, iron, aluminium and copper, precious metals like gold and silver, and a wide range of plastics, to harder materials like ceramics, tiles, gemstones and masonry. Use a ball or spherical-shaped carbide burr to create concave cuts in your material or to shape and hollow out an area. Small carbide ball burrs from as tiny as 0.5mm in diameter are ideal for intricate carving projects. Many wood carvers, stone carvers and metal engravers use these carbide carving burrs in a hobby drill, micro motor or a high-speed handpiece. As we mentioned before, make sure to use a rotary handpiece that runs true. i.e with no wobble.

4. What Speed or RPM should you use your Carbide Burrs?

There is also a cutter known as a left-hand cut carbide burr which you would use if you needed to reverse the rotation of the burr due to a double angle for instance. Shank diameter sizes of your carbide burrs: Die grinder bits can be used on a multitude of materials: metals including steel, aluminium and cast iron, all types of wood, acrylics, fibreglass and plastics. Carbide burrs are also perfect for working on softer metals such as gold, platinum and silver as they last a long time with no chipping or breaking.

That said, I can’t deny the fact that nothing can beat cordless die grinders when it comes to portability. If portability is more important for you, then the cordless tool is your best friend. Pneumatic Die Grinders They also make easy work of both hard and softwoods. Surpassed in outright hardness only by natural and synthetic diamonds, the bits exhibit substantially longer run times than comparable burrs optioned in HSS steel, won’t show signs of wear or metal fatigue due to high working temperatures, and can be used without issue at real high RPMs. Who Are They for?

All mains-powered and cordless die grinders have an electronic safety shutdown. The motor is switched off immediately when the tool used jams. This protects user and machine from sudden reverse torque. An integrated overload protection ensures long service life of the motor. The restart protection prevents unintentional start-up of the machine after a power cut to protect the user. The handy and slim design permits safe and low-fatigue handling of the tools in any working position and thus prevents a dangerous loss of control. Die grinders with long grinding spindle have a removable protective rubber cap for comfortable and safe working. Yes, the clue is in the title...Ideally, solid carbide burrs are used in Air Tools i.e. Die Grinders, Pneumatic rotary tools and high speed engravers. Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools such as a Dremel. Simply put, a rotary burr refers to a tool or material that is specifically manufactured and designed to carry out the removal of materials in metal fabrication. While these tools are designed to rotate at a relatively high speed, they can also manipulate the materials they are working on.

Materials that single-cut options work best in can range from ferrous metals like stainless and tool steel or cast iron, as well as aluminium and copper.Besides the differences in use and the materials, they work best in single and double-cut options and also are distinguished by how they operate. The first produces larger chips, so getting the finish you want may take longer. Additionally, double-cut types are easier to control with the finer cutting profiles and are the ideal type for beginners. Shapes and Sizes Choose from 60-degree or 90-degree angle countersink burs, sometimes referred to as carbide cone burrs. These tool bits are ideal for beveling, counter-boring, chamfering and for getting into acute angled areas of your work. Wonderful for material removal and harder metals. A die grinder is a small, handheld power tool that has a rotating spindle where a collet holds the cutting bit. The grinding bit that rotates at very high speed is used for removing material from the work-piece. They look similar to rotary tools and are usually powered by compressed air or electricity. Choose from an end-cut cylinder (with a cutting edge on the end) for contour finishing. Cylinder without end cut (flat on the end and no cutting edge) for contour finishing and right-angled corners or a round nose or ball nose shape which is a cylinder-shaped carbide burr but with a rounded head. A unique wheel-shaped burr with a smooth top, round edges and fluted sides. Great for channel work and shaping. Countersink Burrs

Flame and oval carbide burrs are ideal for rounded contouring and end milling, and countersink burrs in either 60 or 90 degrees in bevelling, countersinking and chamfering. To extend the versatility and the jobs that the bits will come in handy, buy a set of die grinder burrs in different shapes.Before we dive into the difference between Tungsten and HSS, you need to know some of the factors that are being used to distinguish between the two. These factors include the types of cut, the size, and the techniques. Carbide burrs are widely used for metalwork, tool making, engineering, model engineering, wood carving, jewellery making, welding, chamfering, casting, deburring, grinding, cylinder head porting and sculpting.
