Copy 35° is the largest of Denitool's three 35° copying (profiling) programs (MicroCopy 35° with VC 0501.., MiniCopy 35° with VC 0702.., Copy 35° with VC 1303..). It uses the 35° rhombic insert VC 1303 (ISO VCGT 1303.., ANSI VCGT 2.52..). Denitool is DENI AG, Veltheim, Switzerland, and its US subsidiary Denitool Inc., Raleigh NC. The program has two parts:

- **Boring bars** for internal turning, copying and back boring: five tool styles (SVOC 5°, SVXC 113°, SVLC 95°, SVVC 72.5°, SVQC 95° back boring), right-hand and left-hand, with carbide shank (with coolant) or steel shank (with or without coolant). Metric shanks ⌀ 16 to 32 mm, inch shanks .625" to 1.250". Minimum bore diameter DMIN from 20 mm (.787") up to 43 mm (1.693"), depending on bar.
- **Square-shank toolholders** for external turning and copying: SVXC 113°, SVLC 95°, SVGC 90° (right/left) and SVVCN 72.5° (neutral), metric 10 × 10 mm to 32 × 25 mm, inch .375" to 1.250".

All bars and holders take the same insert size, screw and driver.

What the page says about the range:
- Good quality is economical: economic operation with well known Denitool performance thanks to highly precise VCGT 1303.. (VCGT 2.52..) inserts and holders.
- Machine well: extremely precise carbide inserts with a great range of geometries and coatings available.
- Reliable: high lifetime and longer replacement cycles.

## Common data for all Copy 35° tools

| Item | Value |
| --- | --- |
| Insert size | VC 1303 (VCGT 1303.. / VCGW 1303.., ANSI VCGT 2.52..): 35° rhombus, 7° clearance, inscribed circle 7.94 mm (.3125"), thickness 3.18 mm (.125"). Insert page: https://www.denitool.com/en/indexable-inserts/i/vc-1303-vc-2-52.html |

| Tightening torque of the screw | 2.20 Nm (19.5 in-lb), see https://www.denitool.com/md/en/tightening-torque.md |
| Shank tolerance (boring bars) | Carbide shank (E) h6, steel shank (A, S) g7. All bar shanks are cylindrical with a clamping flat. |
| Coolant | E and A bars have an internal coolant channel to the insert; S bars have none. Toolholders: no internal coolant is listed. |
| Hand | Bars: right-hand (R) and left-hand (L) in every size. Holders: R and L, SVVCN neutral (N). |
| Drawings | The tool drawings on the page show the right-hand tool. |

## Designation and abbreviations

Boring bar example: **E20S SVLCR-13**. Full key: https://www.denitool.com/md/en/boring-bar-designation.md

| Part | Meaning |
| --- | --- |
| E | Shank type: E = carbide with coolant, A = steel with coolant, S = steel without coolant |
| 20 | Shank diameter in mm (inch bars: sixteenths of an inch, e.g. 12" = 12/16" = .750") |
| S | Length letter: M = 150 mm, Q = 180 mm, R = 200 mm, S = 250 mm, T = 300 mm (inch bars use the same mm lengths) |
| S (second) | Insert clamped by a screw |
| V | Insert shape V = 35° rhombus |
| L | Tool style: O = 5°, X = 113°, L = 95°, V = 72.5°, Q = 95° backwards (back boring) |
| C | Insert clearance angle 7° |
| R | Hand: R right, L left (holders: N neutral) |
| -13 | Insert size 13 (VC 1303..) |

Inch bars carry an inch sign after the length letter, e.g. `E12S" SVQCR-13` (the shop writes it as a typographic ”). Inch toolholders carry it before the shank digits, e.g. `SVXCR "0808 G13` (shop: “ or ”).

Toolholder example: **SVXCR 2020 K13** = screw clamping (S), V insert, style X (113°), 7° clearance (C), right-hand (R), shank height 20 mm × width 20 mm, length letter K (125 mm), insert size 13. Holder length letters: G = 90 mm, H = 100 mm, K = 125 mm, M = 150 mm, P = 170 mm.

| Abbreviation | Meaning |
| --- | --- |
| KAPR | Tool cutting edge angle, measured from the feed direction |
| 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 (bars) or the shank reference side (holders) to the cutting corner |
| h × b | Toolholder shank height × width |
| H | Height of the bar shank across the clamping flat (drawing only) |
| WF2 | Second functional width shown on the drawing |
| LDRED | Length of the reduced neck on bars with a neck (drawing only) |
| GAMP, GAMF | Axial and radial rake angle (drawing only) |

Carbide (E) bars reach deeper than steel bars of the same shank: CLMBD = 6 × DCON for carbide, 4 × DCON for steel (for example 120 mm vs 80 mm at ⌀ 20 mm).

In the tables below each row is one size; the left-hand bar has identical dimensions. Metric tables: mm, inch in brackets. Inch tables: inch, mm in brackets.

## Inserts VC 1303 (VCGT / VCGW 1303..)

All Copy 35° bars and holders take the full VC 1303 range. Designation example: VCGT 130304 FN-18M DX2 = V (35° rhombus), C (7° clearance), G (tolerance class G: inscribed circle ±0.025 mm, thickness ±0.13 mm), T (chip breaker on one face; W = without chip breaker), 13 (cutting edge length 13 mm), 03 (thickness 3.18 mm), 04 (corner radius 0.4 mm), FN-18M (geometry: F = sharp edge, N = neutral, 18 = 18° rake angle, M = polished rake face), DX2 (grade). In the geometry codes, F = sharp edge, E = rounded edge, N = neutral, R = right-hand, L = left-hand, W = wiper, M = polished rake face. The number stands for the rake angle in degrees for FN-18M / EN-18M (18°), FN-25M and -25 (25°) and FR-15W (15°); FN-250 also has 25°. Exceptions per the catalog: FL-10 / FR-10 and FL-15 / FR-15 have a 12° rake angle, FR-01W 20°. Key: https://www.denitool.com/md/en/insert-designation.md

Corner radius codes: 005 = 0.05 mm, 01 = 0.1 mm, 02 = 0.2 mm, 04 = 0.4 mm, 08 = 0.8 mm, 00 = wiper without corner radius.

## Cutting data

The page embeds four documents (Google Drive viewers) in collapsible sections labeled "Metric", "Inch", "Cutting Data Int'l" and "Cutting Data U.S.". This file does not reproduce their values. Recommended ranges of vc, f and ap per ISO material group (P, M, K, N, S, H) are also published per insert on https://www.denitool.com/en/indexable-inserts/i/vc-1303-vc-2-52.html

## How to find and order

Store API search (Switzerland), one tool style at a time. The hyphenated form `-13` finds boring bars only, because toolholders are written without the hyphen:

```
curl -s "https://ch.denitool.com/wp-json/wc/store/v1/products?search=SVQCR-13&per_page=50"
```

This returns the 18 right-hand SVQC bars, metric and inch (e.g. E20Q SVQCR-13, A32T SVQCR-13, E12S” SVQCR-13). Replace SVQCR by SVOCR, SVXCR, SVLCR, SVVCR or the L variants. The US store (Denitool Inc.) works the same: `https://store.denitool.com/wp-json/wc/store/v1/products?search=SVQCR-13&per_page=50`

Toolholders: `https://ch.denitool.com/wp-json/wc/store/v1/products?search=SVVCN&per_page=50` (returns SVVCN ..13 and the smaller ..07 holders of MiniCopy 35°; filter on the suffix 13).

Inserts: `https://ch.denitool.com/wp-json/wc/store/v1/products?search=VCGT%20130304&per_page=100`. Search by geometry (e.g. `search=FN-18M`) or grade also works. The search is a substring search: `search=SVXCR` also returns the smaller SVXCR-07 and -05 bars of MiniCopy 35° and MicroCopy 35°, so filter on `-13` or `13`.

In the shop, inch designations use typographic quotes (”, “). Search with the style code (e.g. SVQCR-13) instead of typing the inch sign.
