1/4" spiral bits with 1 1/2" cutting depth

I saw a post for longer Spiral bits and can’t find it. I want to be able to cut to 1 1/2" depth in 8/4 wood.

McMaster has some. You can filter by cut length.

I have used “reduced neck”, “extended reach”, and “extra long” as key words in the past to find such endmills.


I have this one. The Amana tool data base has it set as a ball nose due to the .1 degree angle or something something so I had to use another one of their tool profiles and just change the cutting lenghth.
