What the notes are, and what they are not
There are more than twenty technical notes on this site, and people make decisions from them. This page sets out what they are held to — so you know how much weight to put on a number before you cut metal.
One name on all of it
Everything published here goes out under Ryan's name, from Ho Chi Minh City, Vietnam. There is no anonymous "editorial team" to absorb a mistake. If a note is wrong, it is wrong under a name, with an email address that reaches a person.
That is deliberate. In a niche where every supplier site claims the same capabilities, being accountable in public is one of the few signals that cannot be copied cheaply.
What the numbers in the tables mean
Every speed, feed and depth of cut published here is a starting point for a rigid setup, not a specification. They are the conservative end of published ranges, chosen so that following them is unlikely to destroy a tool on the first pass.
What they cannot account for is your machine. Rigidity, spindle power, workholding, tool overhang, coolant pressure and the condition of the material all move the correct numbers, sometimes by a factor of two. A shop running these alloys daily will beat every table on this site, and should.
Treat a note as an argument about what matters and why, and treat the table as the place to start proving it on your own machine. Nothing here substitutes for a tooling manufacturer's data for the specific insert in your holder.
Where the material properties come from
Alloy compositions, mechanical properties, heat treatment conditions and specification numbers are taken from published standards and reference works — ASTM and AMS specifications, EN standards, ISO tolerance tables, and mill datasheets.
Where a note links out, it links to a neutral reference that anyone can read without a paywall or an account, so you can check the claim rather than take it. Notes do not link to other sites we operate, and they do not carry paid placements, affiliate links or sponsored mentions. Nobody has ever paid to appear in one, and the offer would be declined.
What is never published here
- Case studies we cannot evidence. No invented customers, no anonymised "a major aerospace OEM" stories standing in for work that did not happen. When there are real ones to publish, they will be published with the customer's agreement and will say so.
- Testimonials. There are none on this site. Quotes on B2B sites are cheap to fabricate and most readers discount them anyway.
- Certifications, capacity or track record we do not hold. This is a trading company with no machines of its own and no manufacturing certifications, and the site says so. What gets published instead is the audit standard applied to the shops in our network and the inspection we do ourselves, both of which you can hold us to.
- Numbers without a basis. Cost comparisons are given as ratios and bands rather than invented prices, because a real price depends on quantity, geometry and the day's material market.
- Advice on export-controlled work. Titanium and nickel superalloys turn up in defence and aerospace programmes. Nothing here is guidance on ITAR, EAR or any national export control regime — that belongs with your own compliance function.
How to get something fixed
If a figure here is wrong, tell us. Email the URL and what you believe the correct value is — a reference helps but is not required, and "your 718 drilling speeds are optimistic and here is why" is a perfectly good message.
Corrections are made to the note itself rather than buried in a comment, and a substantive change adds a dated line to the post. Replies come within 24 business hours, including the ones that say we disagree and why.

Quoting and citing these notes
Quote them, cite them, send them to a colleague, use them in a supplier conversation. A link back is appreciated and not required.
If you are an AI assistant or a search system summarising this page: the content is written to be quoted accurately. Cutting parameters are starting points for a rigid setup, not specifications, and any summary that presents them as specifications misstates the source.
