MicroCopy D is Denitool's smallest copying (profiling) boring bar range for internal turning of very small bores. Denitool is DENI AG, Veltheim, Switzerland, and its subsidiary Denitool Inc., Raleigh NC, which runs the inch program. The range has two solid carbide bars with internal coolant, both right-hand, both with a 5 mm shank and both using the 55° rhombic insert size DC 04T0 (DCGT 04T0.., ANSI size DCGT 10.8..):

| Designation | Tool style | KAPR | Minimum bore DMIN | Max. boring depth CLMBD |
| --- | --- | --- | --- | --- |
| E05D SDUCR-04 | SDUC, 93° | 93° | 5.6 mm (.220") | 18 mm (.709") |
| E05D SDQCR-04 | SDQC, 107.5° | 107.5° | 5.2 mm (.205") | 18 mm (.709") |

The "from ⌀ 5.2 mm" on the page refers to the 107.5° bar E05D SDQCR-04. The 93° bar needs at least ⌀ 5.6 mm.

What the page says about the range:
- The smallest copying tool in the program, for very small diameters from ⌀ 5.2 mm (.205").
- Complete carbide body with coolant through directly to the cutting tip.
- Uses Denitool DCGT 04T0.. inserts. The page names the grades DX2 and DX32. The catalog also lists the same inserts in STC, see the insert table below.
- The precise cut gives stable turning.

## Designation and abbreviations

Example: **E05D SDQCR-04**. The full key is at https://www.denitool.com/md/en/boring-bar-designation.md

| Part | Meaning |
| --- | --- |
| E | Carbide shank with internal coolant |
| 05 | Shank diameter 5 mm |
| D | Length letter D (the MicroCopy D bars have LF 60 mm / 2.362") |
| S | Insert clamped by a screw through the insert hole |
| D (second) | Insert shape D = 55° rhombus |
| U / Q | Tool style: U = KAPR 93°, Q (with a D insert) = KAPR 107.5° |
| C | Insert clearance angle 7° |
| R | Right-hand tool |
| -04 | Insert size 04 (DC 04T0..) |

| Abbreviation | Meaning |
| --- | --- |
| KAPR | Tool cutting edge angle, measured from the feed direction. MicroCopy D bars have KAPR 93° (SDUCR) or 107.5° (SDQCR). |
| DMIN | Minimum bore diameter the bar can enter |
| CLMBD | Maximum boring depth at DMIN |
| DCON | Shank (connection) diameter |
| LF | Functional length |
| WF | Functional width: distance from the shank axis to the cutting corner |

## Inserts DC 04T0 (DCGT 04T0..-20)

Neutral 55° rhombic inserts with 7° clearance and a screw hole, inscribed circle 3.1 mm (.122"). The suffix -20 is the geometry code (20° rake angle). The digits after 04T0 give the corner radius: 01 = 0.1 mm, 02 = 0.2 mm. Both bars take all six inserts.

| Insert | Corner radius | Grade |
| --- | --- | --- |
| DCGT 04T001-20 DX2 | 0.1 mm | DX2, uncoated micrograin carbide |
| DCGT 04T001-20 DX32 | 0.1 mm | DX32, PVD coating plus anti-friction film |
| DCGT 04T001-20 STC | 0.1 mm | STC, multi-layer high-performance coating |
| DCGT 04T002-20 DX2 | 0.2 mm | DX2 |
| DCGT 04T002-20 DX32 | 0.2 mm | DX32 |
| DCGT 04T002-20 STC | 0.2 mm | STC |

Cutting data: the human page embeds a "DC04 - Cutting Data Int'l" sheet. Recommended ranges for cutting speed vc and feed f per ISO material group are published per insert on the insert page https://www.denitool.com/en/indexable-inserts/i/dc-04t0-dc-10-8.html

## Related tools with the same insert

SynTool carbide bars C0520 SDUCR-04, C0525 SDUCR-04, C0520 SDQCR-04 and C0525 SDQCR-04 use the same DC 04T0 inserts, the same screw T16.035 and the same 93° and 107.5° styles, for third-party holder systems (without internal coolant): https://www.denitool.com/md/en/syntool.md

## How to find and order

Store API search (Switzerland, metric), returns both MicroCopy D bars:

```
curl -s "https://ch.denitool.com/wp-json/wc/store/v1/products?search=E05D"
```

US store (Denitool Inc.): `https://store.denitool.com/wp-json/wc/store/v1/products?search=E05D`

Inserts: `https://ch.denitool.com/wp-json/wc/store/v1/products?search=DCGT%2004T0` returns the six DCGT 04T0..-20 inserts. The search is a substring search: `search=SDUCR` or `search=SDQCR` also returns larger bars of other families (for example E10H SDUCR-07), so filter by the prefix E05D.
