About This Product
If you’re doing any serious drilling—especially in hardened or alloyed steels—you already know that standard HSS bits just don’t cut it.

That’s where this Sowa 7/16-inch Series Z spade drill blade comes in.

It’s made from HSCO T15 super cobalt steel and finished with a TiAlN (titanium aluminum nitride) coating.

That combo gives you crazy heat resistance and wear protection, so the blade keeps cutting long after cheaper inserts have given up.

The 132° point is a real sweet spot—it bites in fast, reduces walking, and helps chips clear out cleanly so you’re not fighting the tool.

Being a Series Z insert, it drops right into any standard Series Z spade drill body, so no adapters or fussing around.

Whether you’re in a tool room, on a production floor, or just doing heavy fab work, this blade is designed to take the heat and keep on cutting.

Use good feed rates, keep the coolant flowing, and this little blade will earn its keep.
