I was not able to find an answer after searching for previous threads.
Is it possible to drill or cut slots in as-hardened high speed steel with carbide tools?
The items in question are 1/8" thick blades for jointer/planer. I have neither EDM nor the ability to heat treat HSS.
The intent is to adapt one or two sets of plain (not drilled or slotted) blades that are readily available to a couple of older machines for which replacement blades have not been available for years. When they turn up on ebay they often don't last long.
In the past I have put holes in thin HSS blades using tubing and an abrasive slurry on a drill press but the process is very slow. If I can at least drill holes spaced apart I can cut out the space in between with miniature cutoff wheels although milling would be easier.
Anybody done this?
