| A spiral flute tap will help too by directing the chips up and out of the hole... The 2 types of spiral give you chips up, or chips down, depending on the direction of the flute's helix. ....Make sure the holes are CLEAR OF CHIPS before running the tap in, especially with a straight flute tap. You should be able to run that tap at 800-1500 rpm all day long with a good quality coolant. |
