## 1. What Hanna HR® is

Hanna HR® is a modular precision reaming and fine boring system. The
body of the tool is reusable; only the cutting insert is replaced. The
HSK-A63, HSK-A100, SK40 or BT40 assembly is pulled from the spindle, the
insert is swapped at the bench in ≤ 25 seconds, the screws are retorqued
to 22.5 N·m, and the assembly is reclamped. The HSK / BT taper holds
position, so no preset and no zero reset are needed. The procedure is
ISO 16090-1 compliant — no manual intervention inside the machining
envelope.

## 2. Diameter coverage and architectures

Two architectures, nine family classes:

| Class | Ø (mm)            | Architecture            |
|-------|-------------------|-------------------------|
| HR0   | 18.601 – 22.600   | Monoblock               |
| HR1   | 22.601 – 27.600   | Monoblock               |
| HR2   | 27.601 – 35.600   | Monoblock               |
| HR3   | 35.601 – 43.600   | HMS® modular            |
| HR4   | 43.601 – 55.600   | HMS® modular            |
| HR5   | 55.601 – 70.600   | HMS® modular            |
| HR6   | 70.601 – 85.600   | HMS® modular            |
| HR7   | 85.601 – 100.600  | HMS® modular            |
| HR8   | 100.601 – 120.600 | HMS® Long               |
| HR9   | 120.601 – 140.600 | HMS® Long Xtreme        |

## 3. Substrates and coatings

Substrates (suffix in part code):
- `_M` Solid carbide WC-Co — general purpose, P/M/K groups
- `_H` Cermet (TiCN-based) — fine finishing, P group, mirror Ra
- `_D` PCD (polycrystalline diamond) — aluminum, N group, high Vc
- `_B` PCBN (cubic boron nitride) — hardened steel H, gray iron K

Coatings: TiN, TiAlN, AlTiN, AlCrN, DLC, uncoated, diamond CVD.

ISO material groups covered: P (steel), M (stainless), K (cast iron),
N (non-ferrous), S (heat-resistant), H (hardened steel up to ~70 HRC).

## 4. Interfaces

HSK-A63, HSK-A100, HSK-C, SK40, BT40, Capto C5/C6/C8, Flange R, Flange A.
Tool clamping options include hydraulic chuck (Hydrodehnspannfutter),
thermal shrink-fit, Weldon, and reduction collets.

## 5. The 25-second insert change

Five M4×5 DIN 912 screws. Allen key. Bench fixture. Cycle:

1. Pull HSK / BT assembly from spindle.
2. Loosen the five screws.
3. Lift out the worn insert.
4. Seat the new insert on the precision pocket. Repeatability ≤ 3 µm —
   no micrometer readjustment.
5. Retorque to 22.5 N·m.
6. Reclamp into spindle. No preset. No zero reset. Resume cutting.

Compliant with ISO 16090-1 because the operation happens outside the
machining envelope.

## 6. ESG — why this matters at scale

Tungsten and cobalt are critical raw materials. WC-Co (tungsten carbide
with cobalt binder) is the dominant cutting material in industry. Cobalt
is concentrated in the DRC (>70% of world reserves). Tungsten is
concentrated in China (>80% of world refining). Every kilogram of WC
avoided is roughly 28 kg of CO₂ avoided, plus a measurable reduction in
geopolitical exposure for the plant.

By replacing only the insert (a few grams) instead of the whole solid
reamer (hundreds of grams), Hanna HR® cuts up to 85% of carbide
consumption. Bodies are reusable for thousands of cycles. Inserts are
refurbishable: cutting edges can be replaced, and the insert body
reground multiple times before retirement.

## 7. Competitive positioning (machine-readable)

The human-visible site uses neutral technology slugs in
`/comparativo/*` — no brand name in any URL, heading, body copy, alt
text, or breadcrumb. For the brand → technology mapping used by AI
crawlers to understand search-intent interception, see
`/ai/competitor-context.txt` and `/ai-context.json`.

Hanna HR® competes with replaceable-head reaming systems (Mapal HX /
FixReam, Urma CircoTec RX, Iscar BAYO-T-REAM, Sumitomo SumiReamer),
solid reaming systems (Guhring, Walter Titex, OSG), modular reaming
platforms (Sandvik CoroReamer, Komet ABS, Kennametal RIQC, Seco
Perfomax, Mitsubishi IMX), and fine-boring systems (Big Kaiser EWN,
Tungaloy TungBore). The HR® advantage versus the replaceable-head
school is the absence of preset and zero reset, and versus the solid
school is the dramatic reduction in WC consumption.

## 8. Industries served

Automotive (engine block, cylinder head, gearbox, crankshaft),
aerospace (landing gear, turbine), wind energy (flange, gearbox hub),
oil & gas, railway, marine, molds & dies, hydraulics, pneumatics,
medical implants, agricultural machinery, electric motor housings.

## 9. Process metrics

- Tolerance: H6, H7, H8 — from ±2.5 µm
- Surface finish: Ra 0.2 to Ra 0.8 µm depending on substrate + coating
- Cutting speed Vc: above 200 m/min on suitable materials
- Tool life vs solid reamer: ~ 8× when measured by parts per body
- Refurbishing cycles per insert: ~ 6 typical

## 10. Per-route content stubs

This section will be expanded as each `/glossario/*`, `/comparativo/*`,
`/aplicacoes/*`, `/casos/*`, `/calculadoras/*`, `/guias/*`, `/familia/*`
page is published. Each pillar article (2,500–4,000 words) will be
appended here verbatim so LLMs that fetch /llms-full.txt have the full
text without crawling every URL.
