Product Description

1 Inch Tungsten Carbide Drill Bits For Hardened Steel Non Ferrous Metals


tungsten carbide drill bits




Drill bits come in a wide range of shapes and sizes, and are available in a variety of materials and coatings. Most tooling and machining operations have a drill bit that’s designed specifically for the task. Here’s a quick overview of several types of drill bits, materials and design types.
 High-Speed Steel (HSS) is a popular material good for drilling into soft steels as well as wood and plastic. IT’s an economical solution for most maintenance drilling applications.
Cobalt (HSCO) is considered an upgrade from HSS because it includes 5-8% Cobalt blended into the base material. This is a great option for drilling into harder steel as well as stainless steel grades.
Carbide (Carb) is the hardest and most brittle of the drill bit materials. It’s used mostly for production drilling where a high-quality tool holder and equipment is used. It should not be used in hand drills or even drill presses. These drill bits are designed for the most demanding and hardest materials.




DB-3D/5D Tungsten steel drill bit is made of imported fine particle tungsten steel material with bending strength of 4300mpa, grain size of 0.6 μm. The cutter adopts special angle design, strict quality control, self inspection rate of 100%, qualification rate of more than 98%, suitable for hole processing of various grades of steel, non-ferrous metals and other materials.
