VNMG 160412 is a 35° rhombic turning insert with 4 usable cutting edges, used mainly for fine profiling, copying and sharp internal corners. We list 48 stock-keeping variants of it from Achteck, HADSTO, covering 钢, 不锈钢, 铸铁, 耐热合金.
The designation encodes the geometry: the first letter is the shape (V), the following letter the clearance angle, then the tolerance class, then size, thickness and nose radius. If you want to check any of it, our ISO insert code decoder breaks the full string down character by character.

Recommended cutting data
The figures below are the manufacturers' published ranges, aggregated across the 48 variants listed on this page. The typical column is the median, which is where most shops end up running. Treat the full range as the envelope, not a target — start around 60–70% of it and work up.
| 工件材料 | Cutting speed vc (m/min) | Typical vc | Feed fn (mm/rev) | Depth of cut ap (mm) | Variants with data |
|---|---|---|---|---|---|
| 钢 (P) | 45 – 620 | 75 – 510 | 0.05–3.3 | 0.2–4 | 29 of 48 |
| 不锈钢 (M) | 70 – 250 | 92.5 – 220 | 0.1–0.72 | 0.8–5.5 | 6 of 48 |
| 铸铁 (K) | 50 – 490 | 72.5 – 300 | 0.05–0.72 | 0.2–3.4 | 12 of 48 |
| 耐热合金 (S) | 20 – 200 | 30 – 90 | 0.23–0.66 | 1.2–3.32 | 6 of 48 |
To turn a cutting speed into a spindle speed for your actual diameter, use the cutting parameters calculator: n = vc × 1000 / (π × D).
Carbide grades available
48 variants of VNMG 160412 are stocked in these grades: AC152P, AT202, AC052P, AC252P, AT210A, HS8115, HS8125, AC100K, AC102K, AC202K, AP200U, HS7120, HS7125, AC202P and others.
Across this range the grades specified most often are AC152P, AT202, AC052P, AC252P, AT210A. Within one brand's range, a higher middle digit usually means a tougher grade — better on interrupted cuts, slightly less wear resistant. See carbide grades explained for how to read the names.
槽型 geometries
断屑槽 stocked for VNMG 160412: PC4, PB3, PD3, SC3, BS, UC4, PC3, KC4, BM, GT, MT, PA1.
The chipbreaker sets the usable feed window far more than the depth of cut does. A roughing geometry run at finishing feed will not break the chip; a finishing geometry pushed into a roughing cut will chip. Match it to the feed you will actually run — chipbreaker selection guide.
Typical applications
- 中加工
- 精加工
- 粗加工

Choosing the right VNMG 160412
Three things decide which variant you need:
- The workpiece material group. This page lists variants published for 钢, 不锈钢, 铸铁, 耐热合金. Pick a grade from the group you are cutting — a steel grade on a superalloy will fail quickly.
- Feed, not depth of cut. The chipbreaker is defined by its feed window. Decide the feed first, then pick the geometry that covers it.
- 刀尖圆角 versus finish. VNMG 160412 is stocked here at 1.2 mm. A larger radius gives better finish at the same feed and a stronger edge, but raises cutting force.

Frequently asked questions about VNMG 160412
What size insert is VNMG 160412?
VNMG 160412 has an inscribed circle of 9.53 mm and a thickness of 4.76 mm. As a rule the depth of cut should stay under about two thirds of the inscribed circle.
What nose radius does VNMG 160412 have?
The nose radius (the last two digits of the designation) is 1.2 mm on the variants listed here. Surface roughness scales roughly with fn²/(32 × RE), so at a fixed feed a larger radius halves Ra.
Which holder does VNMG 160412 fit?
The holder designation must carry the same shape letter (V) and the same size digit. Send us your holder code and we will confirm the match before you order.
How many VNMG 160412 variants do you stock?
48 variants from Achteck, HADSTO, listed below with grade, chipbreaker and the published cutting data where the manufacturer provides it.
What cutting speed should I run for VNMG 160412?
For 钢, the published range across these variants is 45–620 m/min, with a typical window of 75–510 m/min. Heavy cuts sit at the bottom of that range, light finishing cuts at the top.
