Where decent quality HSS and carbide tool blanks?

(1/1)

PekkaNF:
There are occasions when even most die hard carbide insert user just have to sulk and grind the (form) tool from HSS or alternative tool from a blank and raid to broken tap box does not inspire.

This one worked fine with low quality indian? HSS, but when I was grinding it, some inclusions/pores were revealed, no big deal on POM, but not very optimal when you have to grind off extra 3mm on small 1/8" blank.

Long story short, where to get decent 2-6 mm sguare HSS blanks and round small fine grain carbide blanks?

Hi Pekka I got a box of Cleveland M-Max cobalt blanks off Ebay years ago. Will last me for life. Good brand. Komet is also good.

Have you looked on Ebay Kleinanzeigen in Germany? search for "Drehstahl"

Thank you

I'd like to be pretty sure which grade of carbide/HSS I'm buying. Some have been pretty disapointing. Got some pretty good old stock Sandvik/Seco, but it is pretty thick section and I need mostly small section.

 M-Max cobalt should be pretty good.
