This is a great option for drilling into harder steel as well as stainless steel grades.
High speed steel drill bits vs carbide.
A typical hss composition is.
Most of its major uses including drill bits and cutting tools sports equipment and the tips of ballpoint pens.
The carbide drill bit is made tungsten carbide powder as matrix and cobalt powder by pressing and sintering as its binder.
We can produce these tools using materials such as carbide and high speed steel.
Summary carbide vs high speed steel.
High speed steel is a high carbon tool steel containing a large dose of tungsten.

The red hardness of high speed steel is 650 but the carbide steel can reach 800 1000.
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.
Cobalt drill bits are better if you need to make a hole in hardened or stainless steel.
The difference between carbide and high speed steel is that the tools made from carbide last longer than the high speed steel.
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.
Replaceable tip drills such as kennametal s kentip fs bits.
It s used mostly for production drilling where a high quality tool holder and equipment is used.
The main difference between them is mainly listed below.
Cutting tools are very important in construction fields.
Cobalt hsco is considered an upgrade from hss because it includes 5 8 cobalt blended into the base material.
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.
Tungsten carbide is extremely hard and abrasion resistance.
Hss high speed steels still playing a very significant role in metal cutting.
Irwin does drill bits right with their m42 5 cobalt high speed steel bits that deliver abrasive resistance when working with tough metals.
Drill ream or bore.
Hss tools have a harness of 62 64 rc.
