MT-Tools for Chiron® Precision+ are Denitool turning tools for combined mill-turn centers from Chiron® with the Precision+ turning option. Each MT-Tool is one ready-to-use monobloc article with the machine interface (HSK-A32 or HSK-A40, Chiron Precision+ version) and the cutting head in one piece, ordered under one designation such as `MT HA4C 060 D2022 B`. The program covers internal turning (boring bars for bores from ⌀ 8.2 mm), external turning and copying, parting-off and grooving, threading, and adapters that take MicroTurn A/S and SynTool shanks. All tools are metric.

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

## Key facts

- Machines: Chiron® machining centers with Precision+ turning (combined mill-turn). Chiron® is a trademark of its owner.
- Interfaces: `HA3C` = HSK-A32 Chiron Precision+, `HA4C` = HSK-A40 Chiron Precision+. The same 63 tool types exist for both interfaces (126 articles).
- Body: hardened steel, internal coolant supply to the insert (all turning, boring, grooving and threading tools).
- Inserts: standard Denitool indexable inserts (VC.. 0501, VC.. 0702, VC.. 1303, CP.. 05T1, CC.. 09T3, DC.. 11T3), D2022 / D2040 cut-off inserts and 16 ER threading inserts. Choose geometry and grade on the insert pages.
- Page claims: economic operation with Denitool performance thanks to precision inserts and interface; the precision cut gives very stable turning under different operating conditions; reliable cutting and chip control.
- Catalog: the page embeds the metric catalog as a PDF preview, "Denitool - Tooling Systems - MT-Tools for Chiron® Precision+ - Metric": https://drive.google.com/file/d/0B0FVd0DDs6fFcFB5THRSQ29PWk0/preview

## Terms used on this page

| Term | Meaning |
|---|---|
| KAPR | Tool cutting edge angle (angle between the main cutting edge and the feed direction). |
| DMIN | Minimum bore diameter the boring bar can enter. |
| DRED | Neck (reduced body) diameter of the boring bar. |
| LDRED | Neck length (reach of the reduced-diameter part). |
| LF | Functional length (from the interface face to the cutting corner). |
| WF | Functional width (from the tool axis to the cutting corner). |
| OAL | Overall length including the HSK shank. |
| R / L / N | Right-hand / left-hand / neutral tool. |
| A / B | Mounting position of the insert, see below. |
| Style (SVXCR etc.) | ISO clamping style + insert shape + tool style + insert clearance + hand, as on the boring bar designation page. |

### A and B versions

Many tools exist in an A and a B version. The difference is how the insert sits relative to the operator standing in front of the machine:

- **B**: the insert top face points towards the operator. The insert is visible and easy to change in the spindle.
- **A**: the insert top face points away from the operator.
- For the cut-off holders `060 D2022` and `060 D2040`, A and B differ in that the blade is turned by 180° in the holder.
- Where the machining situation allows both, B is the practical default (visible insert, easier insert change).

### Reading a designation

Pattern of the article list (reading aid):

`MT` + interface (`HA3C` or `HA4C`) + size group + style code + position (A/B).

- Boring bars: 4 digits = neck diameter DRED (2 digits, mm) + neck length LDRED (2 digits, mm). Example: `MT HA3C 0824 VXR05 A` = DRED 8 mm, LDRED 24 mm, insert shape V, style X (KAPR 113°), right hand, insert size 05 (VC.. 0501), position A.
- Turning, grooving and threading holders: `060` = functional length LF 60 mm, then style letters + hand (R/L/N) + insert size. Example: `MT HA4C 060 VXR13 B` = V insert size 13 (VC.. 1303), style X, right hand, position B.
- Cut-off holders: `060 D2022` / `060 D2040` = holder for D2022 (2.2 mm) or D2040 (4.0 mm) cut-off inserts.
- Adapters: `AS04`, `AS06`, `AS08` = for MicroTurn A/S shanks ⌀ 4 / 6 / 8 mm; `ST04`, `ST05`, `ST06` = for SynTool bars ⌀ 4 / 5 / 6 mm.

## Boring bars (internal turning), right hand, position A

Dimensions in mm. OAL differs by interface (HA3C / HA4C); all other values are the same. Corner radius of the reference insert: 0.2 mm.

\* LF of `0824 VOR05 A`: 48 mm for MT HA4C. The shop lists 58 mm for MT HA3C 0824 VOR05 A; confirm with Denitool support before relying on it.

Bore range: DMIN 8.2 mm (.323", copying style SVOCR with KAPR 5°) to 17.5 mm (.689"). Neck diameters 8, 10 and 12 mm; neck lengths 24 to 48 mm.

## Turning, cut-off and threading holders (`060` group)

## How to find and order

Store API (Switzerland and Liechtenstein, prices in CHF):

```
curl "https://ch.denitool.com/wp-json/wc/store/v1/products?search=MT%20HA4C&per_page=100"
```

Returns the 63 HSK-A40 articles. Use `search=MT%20HA3C` for the 63 HSK-A32 articles, or a narrower term such as `search=MT%20HA4C%20060` (15 holders). The same metric designations are listed in the US shop: `https://store.denitool.com/wp-json/wc/store/v1/products?search=HA4C&per_page=100`. Product pages in the CH shop follow the pattern `https://ch.denitool.com/de/shop/mt-ha4c-060-d2022-b/`.
