Product Detail
Square / Flat End Mill
Carbide square/flat for ferrous pocket-wall perpendicularity and sharp shoulder geometry.
Geometry lane · 90° ferrous shoulders
Pocket-wall perpendicularity and sharp shoulder callouts
Fixture plates and steel housings need flat cutting edges that hold a square shoulder. This page opens on wall geometry—true sharp corner vs tiny break, slot clearance, floor flatness separate from perpendicularity. Aluminum abrasive corner growth is a different door.
Also known as: flat end mill—same industrial noun for this carbide square series; no merge with PCD square.
Wall geometry field table
| Callout | What to confirm |
|---|---|
| Corner intent | True sharp vs allowed micro-break |
| Slot width vs tool Ø | Clearance and pass count |
| Wall perpendicularity | Separate from floor flatness |
| Flute preference | e.g. 4-flute finish—or open 4-flute attribute page |
| Grade | Steel / stainless / CI |
Forks off this geometry page
- Programmed corner R for strength → corner radius / bull nose
- Fillet / 3D blend → ball nose
- Abrasive aluminum walls radiusing corners → PCD square end mill
- Wide decks → indexable face
Steel shoulder geometry intake
- Grade (steel/stainless/CI)
- Ø, LOC, flute preference, corner intent
- Shoulder / slot / pocket tolerances
- Holder runout budget
- Any wall taper history (geometry, not Al abrasion)
Square / flat geometry FAQ
Flat end mill redirects?
Alias language stays as body text on this URL—no synonym 301 into PCD square.
Why a separate PCD square page exists
Aluminum abrasive corner-growth failure is a different production pain than steel wall geometry.
4-flute attribute only?
If flute count is the only question, see 4-flute carbide end mill; keep full wall geometry here.
