The Denitool Corner and Face Milling Cutter (designation series FZ ... RSAS-06) is an indexable end mill for shoulder (corner) milling with an exact 90° angle and for face milling. Six sizes cover cutting diameters from 16 mm to 50 mm (.630" to 1.969"). Each cutter carries 3 square SP 06 inserts (SPHT 060204 type) with 4 usable cutting edges each. The cylindrical (straight) shank of ⌀ 16 mm or ⌀ 20 mm clamps in collets, hydraulic chucks and shrink-fit chucks, so the cutters are used on machining centers and other milling spindles.

The page slogan is "Smoothly cutting 90° angles". The page claims: economic operation with precision inserts and milling cutter body, extremely stable milling under different operating conditions thanks to the precision cut, and steady, reliable cutting.

Denitool is made by DENI AG (Veltheim, Switzerland) and its subsidiary Denitool Inc. (Raleigh NC, inch program).

## Key features (from the Denitool master data description)

- Exact 90° tool cutting edge angle (KAPR 90°) for square shoulders.
- Low axial and radial runout, suited to tool and fixture making.
- Square inserts with 4 usable cutting edges instead of 2, so insert consumption per edge drops by half.
- Precise SPHT / SPGT 06 insert types, so the inserts are evenly loaded.
- Cylindrical shank for collets, hydraulic chucks and shrink-fit chucks.

## Terms used on this page

- **DCX**: maximum cutting diameter (the milled diameter at the insert corners).
- **DCIN**: internal cutting diameter (inner diameter swept by the inserts, as recorded in the master data).
- **DMM**: shank diameter.
- **LS**: shank length. **LU**: usable length (max. recommended). **OAL**: overall length.
- **APMX**: maximum depth of cut.
- **KAPR**: tool cutting edge angle (ISO 13399). 90° gives a square shoulder.
- **SP 06 / SP0602**: ISO insert seat: square insert (S), 11° clearance (P), inscribed circle 6.35 mm, thickness 2.38 mm (code 02). See https://www.denitool.com/md/en/insert-designation.md

## Designations and dimensions

All six sizes: KAPR 90°, right-hand, 3 inserts (effective teeth 3), insert seat SP0602, APMX 5.9 mm (.232"), steel body, cylindrical shank. Inch values are converted from mm (1 in = 25.4 mm) and rounded to 3 decimals.

Reading the designation (pattern observed across all six articles): `FZ` = family, first two digits = cutting diameter DCX in mm, next two digits = shank diameter DMM in mm, `RSAS` = style (R = right-hand, S = square insert, 90° cutting edge angle), `-06` = insert size SP 06. The same metric designations are sold in the Swiss shop and in the US shop (store.denitool.com). There is no separate inch-sized FZ series.

`ch.denitool.com` is the Swiss shop (Switzerland and Liechtenstein), `store.denitool.com` the US shop. Searching `FZ` plus the size (e.g. `FZ 2020`) returns that cutter. Note: the style search `RSAS` also returns the LTH / LTS ... RSAS-06 articles, which are a different product line, so filter the names starting with `FZ`. The response lists name (the designation), price and stock status.
