In Metal cutting, Carbide tools have gradually taken over HSS tools in many of the tool applications; but still HSS is widely in use in some specific segments of tools like drills, reamers, taps, form turning tools, gear hobbing and gear shaping cutters, side and face mills, end mills, slab milling and straddle milling cutters, slitting saws, form milling cutters and broaches
The advantage of HSS over carbide is its strength to withstand cutting forces and the low cost of the tools. From the tool life point of view, HSS performs very well at intermittent cutting applications. But the greatest limitation of HSS is that its usable cutting speed range is far lower when compared to Carbide.
In the vast majority of cutting applications, namely turning, boring, and face milling, Carbide tools and inserts have near-totally taken over HSS tools, and HSS has become virtually extinct in these applications. But that’s not the case with drilling.
