Product Detail
PCD Square End Mill
PCD square for abrasive aluminum corner-growth failures on prismatic walls—wear-evidence RFQ.
Failure-mode lane · abrasive Al corner growth
When aluminum pocket walls radiused themselves mid-shift
High-silicon aluminum turns a sharp carbide corner into a measurable radius before lunch. This page opens on that corner-growth failure on prismatic Al walls—shoulders, open slots, pocket sides—not on steel fixture perpendicularity geometry.
Corner-growth failure checklist
- Walls measure out-of-square after a few dozen Al parts
- Operators swap carbide squares mid-shift to chase the radius
- Feature stack stays prismatic—no freeform ball path
- Si-rich alloys polish the corner faster than floor wear
Abrasion evidence packet
- Alloy / Si% from print or cert
- Corner wear photo from the carbide incumbent
- Ø, LOC, sharp vs micro-radius intent on the Al feature
- Wall & floor tolerances that failed after corner growth
- Machine / holder notes
Disambiguation
Sharp ferrous shoulders and pocket perpendicularity → carbide square / flat end mill. Keep abrasive aluminum corner failures on this PCD URL.

Al corner-failure FAQ
Can I finish steel molds here?
No—use the carbide square series for ferrous wall geometry.
Wide sealing decks?
Prefer PCD monoblock or indexable face series.
Same as carbide square?
No. Carbide square opens on 90° steel shoulder geometry; this opens on Al abrasive corner growth.
Corner wear evidence ready?
PCD square quotes are alloy-wear driven—failure photos first, then corner layout.
