- Tungsten carbide is a composite material, although it looks like a metal, it is a composite of Tungsten carbide powder mixed with cobalt as a binder metal, the resulting material is more like a ceramic than a metal. It is a very hard material being a 9 on the Mohs scale where diamond is a 10 and hard steel around 5. It will chew down into most anything but the hardness makes them brittle with virtually no plasticity. Unstable drilling can result in a broken bit. These drills like a a rigid dri

4. JIUWU 13pcs Tungsten Steel Cemented Carbide Twist Drill Bits, Metal Drill YG Alloy Blade, for Stainless Steel Copper Aluminum Zinc Alloy, 3 4 5 6 7 8 9 10 11 12 13.5 14 15mm
Key Features:
- Material: The low tungsten content of our drills is not suitable for stainless steel, aluminum alloy, colored steel and other hard metals. It mainly for pig iron and cast iron.
- The mistake that a lot of people make is using high speed steel twist drills at high speeds. If you search for “machining speeds and feeds” you will find a lot of information about the correct speeds to run cutting tools against different types of metal. Twist drills are the category of cutting tool you are looking for.
- As soon as the heat starts to build up on the tip, the drill bit can lose the hardness that make it a cutting tool. Using HSS drills at low rpm with cooling fluid or lubricant can provide a large quantity of successful holes in metal. TThere have chunks of carbide on the end, and carbide will make easy work of even the hardest steel, and allow you to use high rpms. (In the process of opening holes to continue to add water for cooling.)
- High toughness, abrasion resistance, high-speed cutting for the high hardness.
- Size: 3mm 4mm 5mm 6mm 7mm 8mm 9mm 10mm 11mm 12mm 13.5mm 14mm 15mm.
