Small-diameter holemaking
Runout, edge condition, and depth-to-diameter decide the result—drill first, ream only when the print demands it.

Micro-Precision & Special Operations — Small Features, Fine Finishes, Honest Scope
Micro and special work fails when the tool is “almost right”: runout, edge prep, and reach dominate. XRZ supports small-diameter holemaking and high-gloss / fine finishing on suitable non-ferrous materials with carbide and PCD geometries quoted from your feature sizes—not a catalog of disposable 3C bits or woodworking PCD blades. Use this hub to open the two solution paths below, or send a print when the feature is thin-wall or non-standard.
SCOPE
What this scenario covers
- Small-diameter holes and fine-feature finishing where the tool approaches feature scale
- High-gloss / fine cosmetic or functional finishes on suitable non-ferrous stocks
- Non-standard edge, neck length, or interference geometry—quoted from prints, not SKU theatre
- Typical part language (generic): precision connector holes, small cavities/slots, high-gloss non-ferrous appearance faces—no branded 3C model names
Large EV aluminum housings live on PCD aluminum high-speed / Automotive paths. Everyday shafts and boxes → General Mechanical. Tough alloys and mold cavities → Difficult Materials.
PRECISION MEANING
What “precision” means here
At micro and fine-feature scale, size and form still matter—but so do edge integrity and measured runout. The tool itself may be close to the feature diameter, so brochure SFM without spindle and holder context is not a plan. We quote from the feature, not from a vanity minimum diameter claim.
CAN / DEFER
Scope table — what we open vs what we defer
| Need | How we handle it |
|---|---|
| Small-diameter drill / precision hole | Small-diameter holemaking subpage |
| Non-ferrous high-gloss / fine finish milling | High-gloss nonferrous subpage |
| Thin-wall, special slot, long-neck geometry | Section below + engineering RFQ (no separate URL) |
| Medical implant / bone-screw full package | Case-by-case RFQ only—no catalog claim page |
| Woodworking PCD blade / hub-size “PCD” confusion | Disambiguation → industrial hole/mill RFQ if that is the real need |
| Phone mid-frame turnkey line | Out of scope as a packaged Solution—print-based RFQ only |
SPECIAL GEOMETRY
Thin Walls and Special Geometries — Quote from the Interference Model
- Thin walls punish radial force, vibration, and deflection—geometry and toolpath must be reviewed together.
- Special edges, necks, and steps need a cross-section or 3D interference model—not a catalog name.
- We do not claim an off-the-shelf “woodpecker” or similar specialty brand SKU. Send the feature; we quote a custom edge.
No separate thin-wall slug unless a stable series landing page exists later. Extrusion taps and CBN gloss specialty pages are intentionally not opened here.

RFQ CHECKLIST
What to send for a micro / special quote
- Minimum feature size (Ø, slot width, wall thickness)
- Tolerance / form / finish callouts that actually matter
- Material grade and condition
- Reach / overhang and interference constraints
- Spindle runout capability and holder / collet system
- Coolant (flood / through-tool) and planned volume
FAQ
Quick answers before you RFQ
Do you sell woodworking PCD blades?
No—XRZ focuses on industrial cutting tools. If your real need is a precision hole or mill feature, send that print for RFQ.
Phone mid-frame turnkey line?
Not a packaged Solution page. Print-based engineering RFQ only—no 3C turnkey marketing claim.
How small can you go?
Feature-driven quote. We do not publish a vanity minimum Ø without metrology and machine context.
Same as Difficult Materials?
Overlap on “hard features,” but this hub is scale & finish; the tough-alloys hub is material severity. See Difficult Materials.
Medical bone screw tooling?
Case-by-case only—no catalog claim page.
ENGINEERING QUOTE
Send the feature sizes—we'll map fine drill, ream, or PCD finish options
Primary tooling entries: PCD reamers and solid carbide drill bits. High-gloss paths also use PCD milling geometries. Special thin-wall work is quote-only.
