COMP Cams 4726 .530 Valve Guide Cutter

Liked it all the way around good tool

First time cutting valve guides for a 454 I’m building and this tool made it a breeze ! Pricy for a one time use but machine shop might even be more , great tool to own for future projects! Super sharp and used with my dewalt drill , no problem! Make sure you purchase the valve guide!

Quality tool, did the job.

Used these to cut down valve guides on Vortec heads to get more valve seal clearance for larger cam. Took some time to get them all cut down but better than taking the heads to a machine shop. Definitely use slow drill setting as spinning too fast will heat things up too much.I used a paint marker so all guides were cut about the same height, and a shop vac to suck up the shavings every few minutes.

I use this and in the first 5 minutes of second blade on top broke off I need to return it

Worked great. Make sure to use correct size pilot and cutting oil.

tool worked well, the trick was to apply moderate pressure and a very slow drill speed for a smooth and even cut.

High quality and cut great

Worked perfect
