Once again you demonstrate you do not possess the art of reasoning.Yeah sorry, that really floored me lol.
Actually I do understand exactly the concept of evidence and that is why I am presenting these anomelies as opposed to dismissing them like some are doing. We have to whether we like it or not go through each one of these anomelies to determine the facts.
That requires unfortunately this back and forth exchange of data and reasoning. That is exactly what I am doing. I have presented a number of anomelies and at the very least issues that need thorough investigation.
No it doesn't. The core made by a copper pipe in a previous tests was shown to make horizontal patterns and not spiral. That is the whole issue here.
Your still missing Petrie point for which Dunns verified. Its not the pitch its the spiraling of the thread that is the problem. In some places it extends to 3 feet without a break. It is this spiral that cuts in and spirals down that gives us the feed rate. It is this feed rate that is beyond the capabilities of a copper pipe with sand and lubricant grinding it away very, very, very slowly.
I am skeptical of the modern image as the depth of cut was greater in core 7 than copper piper examples. Here is Dunns result from tests with copper pipe.

As you can see the copper pipe leaves little trace of engraved lines into the granite. Which makes sense as there is nothing cutting into the granite on a 90 degree angle. Thats why Petrie mentions some sort of diamond fixed point cutting into the granite protruding from the pipe or shaft at a 90 degree angl;e from the pipe doing the cutting.
A copper pipe is flush on its sides so the grinding action is happening at the base and not the sides. This will leave slight horizontal lines or stratches as it grinds deeper. But it certainly won't cut into the granite being a much softer substance and having no cutting points protruding into the granite.

As you can see in other independent tests this one from the paper below the abrasions leave light stratches and not cut grooves.
Another problem identified is that some drill holes are in corners or against walls making it impossible to have a pipe and bow setup which would be restricted. Also drill holes overlapping and on edges, and massive drill holes.
So its not an open and shut case either way and there's a lot to be explained if conventional tools in the records are said to be the only tools used to explain these anomelies in the stones. Like how do they drill in corners, on edges, and larger holes. But the main issue is the spiral cuts that go deep and wind down that a copper pipe and sand abrasion cannot produce.

Notice the spiral thread pattern.

Finally we have an analysis of the possible methods of how the holes were drilled which sort of supports Petries original findings that some sort of fixed point such as diamond was doing the cutting.
A functional analysis of the drilling of a granite sarcophagus lid from the Old Kingdom period has begun to suggest resolutions to an important scholarly controversy between Petrie and Lucas, and has produced some preliminary insights into the hitherto speculative technology used. These are: 1) loose, dry abrasives (except diamond) did not produce concentric lines; 2) fixed abrasives or those in a watery slurry or a lubricant such as olive oil did produce concentric cutting lines; 3) corundum and diamond cannot be ruled out as not having been used to drill granite.

I will once again state my position. I don't know how these were done. I am not claiming any specific tech. I am merely providing evidence that shows anomelies in the mainstream narrative that these precision results are done with the tools they found them with. This is supported by other findings.
Reading Tool Marks on Egyptian Stone Sculpture
This systematic recording of tool marks also generates a number of new questions, and there are still some tool marks that cannot yet be explained by existing scholarship. Are there, as Stocks suggests, tools that are completely missing from the archaeological record? Maybe points made from hard minerals like corundum, microcrystalline varieties of quartz or other gemstones could be embedded in another material like copper or wood and used as a graver. All of these hypotheses require further investigation, including the consideration of contemporary gemstone carving technologies around the region.82

(1) It is patently ridiculous for you to criticize the cutting process with copper tooling when you make the same mistakes even after being corrected, it is not the copper that does the cutting, the primary mechanism for cutting is made by the abrasive. Copper alone will not cut through granite.
This is why it is called abrasive cutting for a reason, the primary role of copper whether it is a tube or a blade is to guide the abrasive during cutting and gives characteristic striation patterns as observed in Petrie’s core samples and the Saqqara sarcophagus.
(2) “ Its not the pitch its the spiraling of the thread that is the problem. In some places it extends to 3 feet without a break. It is this spiral that cuts in and spirals down that gives us the feed rate.”
Let me give you some advice making up word salad does not make you look smarter but has the opposite effect.
Dunn has expressed the feed rate as 0.1 inch/revolution which by definition is the pitch, he even has a diagram to illustrate this.
What he has done is to take the average value of the pitch for each revolution which he has expressed as the feed rate.
The problem as I stated previously which clearly you do not understand, Dunn has assumed this average pitch value is a constant which would only make sense if the variance was very small, which is not the case as seen in Petrie’s data, and the No 7 core and experimental samples.
It means his calculated feed rate is nonsensical.
(3) Then there are your images which prove nothing particularly when you cannot understand how the cutting process for copper blades/tubes with abrasives work.
I note how in typical style you conveniently ignored the close up images which compared the Petrie and experimental samples which are similar and disproves Dunn’s hypothesis due to the variable pitch.
