Maurice,
I understand where you are coming from. However, after nearly 40 years of experience in turning and drilling all type of materials. I can't help but wonder if the millions spent on drilling research at high speeds is really focused on the home market.
What you gain from drilling at high speeds on the home workshop is only seconds, that should really not count. In manufacturing then yes, that will count. This is where the drill manufacturers make there money.
But if you asked the drill manufacturers to spec one to drill plastics, they you would get a different design, and a hefty cost to match.
While I fully understand you problems, but you must always understand that even after 20 years of experience you can learn something from the fact that drilling plastics at high speed is frowned upon from many on this forum. If you tot up their experience then that would spread over 300 years ( Brian's alone does half that)
Anyway. I don't believe anyone was getting at you personally ( even Walter can come across a bit strong, but that's Walter) just the surprised that someone was drilling plastics at such high speeds.
I too have a colt, but I don't drill at high speeds on plastics, that's why my comment was one of surprise.
If you feel I have come across incorrectly then please feel free to pm me and I will discuss outside this forum.
I now believe that there is a misunderstanding from allot of craftsman that drilling and turning speeds are miss understood and it doesn't matter how modern you are, it's a fact, materials will only drill at the speeds they want to be drilled at and not what they are told to be drilled at..
