MT-Tools for Willemin-Macodel® are super compact internal (ID) and external (OD) turning tools for the combined mill-turn centers Willemin-Macodel® 408 MT, 508 MT and 508 MT2. Every tool has the dedicated interface **HSK-E40 Willemin-Macodel** (clamping diameter DCON 40 mm) and is supplied as one monobloc article under one designation, for example `MT HE4W 1030 VLR07` or `MT HE4W 060 D2022`. They are widely used in the industry, for example by watchmakers and in medical and aerospace manufacturing.

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

## Terms used on this page

| Term | Meaning |
|---|---|
| MT | MT-Tools, Denitool tools with a machine-specific interface for mill-turn centers |
| HE4W | Interface HSK-E40 Willemin-Macodel (all `MT HE4W` articles carry this interface) |
| KAPR | Tool cutting edge angle, angle between the main cutting edge and the feed direction |
| PSIR | Tool lead angle (ISO 13399), 90° minus KAPR |
| DMIN | Minimum bore diameter the boring bar can enter |
| CLMBD | Maximum machining depth (reach) at the minimum bore diameter |
| DRED | Neck diameter of the boring bar |
| LF | Functional length, from the HSK contact face to the cutting corner |
| OAL | Overall length |
| WF | Functional width, from the tool axis to the cutting corner |
| LH | Head length (external holders) |
| IIC | Insert size code: insert shape + size, e.g. VC0702 = VC.. 0702.. insert |
| R / L / N | Right hand / left hand / neutral |
| SCMP, SCUP, SVLC, SVQC, SVOC, SVVC, SVXC, SVZC, SDNC | ISO clamping style (S = screw clamping) + insert shape (C = 80° rhombic, V = 35° rhombic, D = 55° rhombic) + tool style letter + insert clearance angle (P = 11°, C = 7°) |

### Reading a designation

Reading aid derived from the catalog data (not an official published key):

- Boring bars: `MT HE4W` + neck diameter DRED in mm (2 digits) + reach CLMBD in mm (2 digits) + insert shape and tool style (2 letters, e.g. `VL` = SVLC) + hand + insert size. Example: `MT HE4W 1030 VLR07` = DRED 10 mm, reach 30 mm, SVLC style (KAPR 95°), right hand, insert size 07 (VC 0702..).
- External holders: `MT HE4W 060` (LF 60 mm) + tool style + hand + insert size, e.g. `MT HE4W 060 VXR13` (SVXC, right hand, VC 1303..). Cut-off holders carry the insert family instead: `MT HE4W 060 D2022`, `MT HE4W 060 D2040`.
- Adapter holders: `AS` + clamping diameter (MicroTurn A/S adapters), `ST` + clamping diameter (SynTool bars).

## Boring bars (internal turning)

All bars: HSK-E40 Willemin-Macodel, right hand, steel body, coolant channel to the insert. Dimensions in mm (inch in brackets for DMIN and reach).

Grades and chip breakers: https://www.denitool.com/md/en/insert-grades.md and https://www.denitool.com/md/en/insert-designation.md

Tightening torque (from the Denitool tightening torque page): T16.035 / T16.045 = 0.30 Nm (Torx T5, driver T5F), T22.045 / T22.050 = 1.00 Nm (Torx T7, driver T7F), T30.090 = 2.20 Nm (Torx T8, driver T8F). The torque page gives no value for T20.055 and T35.110; ask Denitool support. See https://www.denitool.com/md/en/tightening-torque.md

## Find and order (Store API)

Public JSON, no key needed. Each result carries the attributes KAPR, DMIN, CLMBD, LF, OAL, IIC (insert size) and INTERFACE. The U.S. store shows inch and metric values.

```
curl "https://ch.denitool.com/wp-json/wc/store/v1/products?search=HE4W&per_page=100"
curl "https://ch.denitool.com/wp-json/wc/store/v1/products?search=MT%20HE4W%201236"
curl "https://store.denitool.com/wp-json/wc/store/v1/products?search=MT%20HE4W%20060"
```

`search=HE4W` returns all 59 tools of this family in the Swiss shop (65 in the U.S. store, including the CLR06 bars). `MT HE4W 1236` returns the seven 12 mm / 36 mm bars, `MT HE4W 060` the eleven external holders. Screws and drivers are separate articles: `search=T20.055`, `search=T16.045`, `search=T7F`.
