Tool for cutting internal keyways etc...

[M-man]

Does anyone know of a tool with inserts that are used in lathe/mill to cut keywas. I know that there are out there coz I have seen one before.. Mabe there are a profile to cut timing pulleys in the same way?

Mattias, www.hornusa.com or www.phorn.de should be able to direct you to their keyway broaching tools. They cut by stroking a broach insert tool into a hole. I suppose you could come up with a method to broach externally as well. Good Luck

add: The horn site is a bit confusing. click on their site then products/catalogs/non-rotating/broaching/ open pdf/ scroll down to info you want.

M-man, I noticed your tag line said "keyways". If you have multiple keyways this can often be accomplished using rotary broaching. Check it out at www.slatertools.com.

M-Man (and others),

I used to broach keyways with Horn's broaching tool until I found out about Razorform Tools. They offer more sizes than horn, and their huge inserts got me 5-10 TIMES more parts per cutting edge over horn's flimsy tooling.

They are kind of a small company, but they are great about overnighting me tools and inserts when I have a hot job. They even hand delivered some inserts same day once!

I'm pretty sure they sell overseas. Check them out:
