| Machine1, Yes Parabolic drills are excellent for aluminum or any soft and gummy material. I use Guring brand and would highly recommend them.

| Yes, you can get high feeds. Defiantly higher than standard drill designs.

| For that thickness, I don't know if you would see an incredible difference. You're still going to want to peck anyway, to chip break. A short carbide drill might do a better job, because it is stiffer. Parabolic flutes stand out for deeper holes, IMO.

| Parabolic drills have a wider web to allow better chip evacuation and coolant flow. They work great on aluminum but if you are only drilling 3/8 thick 6061 plate, I doubt that you will notice any significant difference. Another option is the solid carbide 3-flute drills (I like SGS brand). You can really plow through aluminum with these drills when drill 2XD or less. HuFlung -- you say that he is going to need to peck anyway to chip break. Do you really think that is necessary on 3/8 thick material? I wouldn't unless the hole size is less than, say, 3/32 or so. |
