Not to pile on here, but reaming out the clamp area of this stem (or really, of any stem) sounds like a Very Unwise Idea. If you compare the thickness of the handlebar clamps of a 26.0 Nitto stem and a 25.4 Nitto stem, you'll see that the metal is the same thickness. You think maybe Nitto knows what they're doing? You think maybe the reason they're not reaming bigger bores in the clamps for 26.0 stems is because all that metal they forge in is necessary for safety?
Modifying a stem that's only available in a single clamp size is problematic, but conceptually understandable; that's why Nitto makes shims to fit 25.4/26.0 bars into 26.0/31.8 stems. But the Nitto Technomic is not a one-clamp-only stem. Nitto has already made hundreds of thousands of stems that are sized exactly right for your need. Doctoring a Technomic is a pointless effort; it's also penny wise and pound foolish. Both 25.4 and 26.0 Technomics are common as dirt (the successor Talluxes are somewhat less so); this eBay search <https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313&_nkw=26+mm+nitto+technomic+stem&_sacat=0&LH_TitleDesc=0&rt=nc&_odkw=26+mm+technomic+stem&_dcat=177827&_sop=15&Steerer%2520Tube%2520Diameter=1%2520in&Material=Aluminum> brings up 60 examples in various reaches from $40-65 shipped. What are your teeth worth to you? Me, I buy my Nitto stems at swap meets. I've had four or five Technomics in both 25.4 and 26.0 over the years; I don't think I've ever paid more than fifteen bucks for any of them. At least three of my current stable are using such recycled stems now. Here's a thought: Why don't you just post a want-to-buy for the stem you need right here (include both clamp size *and* reach, which you haven't mentioned at all), and see what shakes out? Your unshattered bones and unshredded flesh will thank you.
