Anyone had much experience with this type of material? I've been working with it for the last few days. Have also been working with a new tool in roughing of these parts. VERY, impressive.

been machining it for years.....turns fine with carbide, gotta watch high speed drills...tapping just sucks....but it makes good mold components that can last for years and years.

Yes drilling with high speed and tapping really sucks. Had an 7/16" x 8" deep hole to put in. Like the material wants to shrink around the tool as it heats up with the high speed. Went to a carbide drill with not one single problem. Tapping is out of the question so all needed threads were thread milled.

high speed steel drill sharpen just alittle off center this will make it cut a tad larger.
also add neg relieve to the cutting edge this will prevent it from wanting to pull. due to the mat'l being gummy.
