Turning Broken Drill Bits Into Lathe Tools

G'day everyone. I have talked before in my HSS vs Carbide video about how broken twist drills can be recycled into lathe tooling. Today I want to demonstrate my method of recycling some used and broken High Speed Steel twist drills into some lathe tools for turning aluminium, brass and plastic.

I think this is a great method for producing specialty form tools and internal profiling tools when they are needed for very specific applications. This is also a great use of High Speed Steel for when you are stating to practice grinding HSS as broken twist drills and much more affordable and easier to obtain than HSS blanks.
