High Speed Steel Drill Bits Vs Carbide

The carbide drill bit is made tungsten carbide powder as matrix and cobalt powder by pressing and sintering as its binder.

High speed steel drill bits vs carbide.

It s used mostly for production drilling where a high quality tool holder and equipment is used. A typical hss composition is. There is a place in the machine shop for high speed steel jobber length drills and chucking reamers but it s probably not on any late model cnc lathes and machining centers. With a heavy duty spiral fluted design for faster chip ejection and a 135 degree split point tip for easy penetration these tools are versatile and durable enough to use on a wide variety of materials.

Drill ream or bore. High quality drill bits are generally made of carbide and high speed tool steel while the former can cut two to three times faster than the latter. High speed cobalt hsco tools are an upgrade from high speed steel hss due to increased heat resistance because of 5 8 cobalt in an alloy. The red hardness of high speed steel is 650 but the carbide steel can reach 800 1000.

Most of its major uses including drill bits and cutting tools sports equipment and the tips of ballpoint pens. This is a great option for drilling into harder steel as well as stainless steel grades. Cutting tools are very important in construction fields. The main difference between them is mainly listed below.

High speed steel is a high carbon tool steel containing a large dose of tungsten. Cobalt hsco is considered an upgrade from hss because it includes 5 8 cobalt blended into the base material. Summary carbide vs high speed steel. Hss high speed steels still playing a very significant role in metal cutting.

Tungsten carbide is extremely hard and abrasion resistance. Hss tools have a harness of 62 64 rc. The difference between carbide and high speed steel is that the tools made from carbide last longer than the high speed steel. Cobalt drill bits are better if you need to make a hole in hardened or stainless steel.
