Harvey Tool Drill / End Mills

[Charlie Pierson]

I am considering using a .078 drill/emill w/ a 90 deg point to make some small slots .085w in 2024 Alum. .220 deep and blind.

The machine is a DMG Sprint 65 w/ 16k rpm available w/ 4x1 speeder.

Oper was previously done w/ a drill for opening then ruff emill followed by finish emill. I am hoping to combine the drill&ruff emill w/ this tool but am concerned w/ dragging the 0 sfm point across the bottom of the slot.

Bottom finish is not a problem cuz' sub-spindle opers will mill down to the slot.

 

Has anyone tried these drill/mills??

If so, whaddya thimk ??

 

thanx in advance,

cp

Charlie,

 

I have not use that specific tool but EVERYTHING I have used from Harvey has always been good quality stuff.

I use drill/mills from MSC all the time. I am not exactly sure what you are planning on using them for, but I use them for slotting+chamfering with no problem.

For Alum, should be fine I only have problems when it comes to using them in Steel the tip chip's fast.

I used some chamfer mills from Harvey Tool a while back on some heat treated stainless and and was very pleased with them. I have also used small endmills from Harvey Tool in aluminum with great results. I have never tried any of there drill/mills but I would give them a try. They make excellent tools.

I have to agree with the others that said Harvey Tool. Also you might want to look at Melin Tool. Try going with the 4 flute for higher feeds and speeds.
