## Notes

- DIN 172 is the press-fit drill bushing with a collar (head, flange): the collar seats on the plate or sits in a counterbore. DIN Media titles it 'Press fit jig bushes, headed' (Bundbohrbuchsen) and lists it as withdrawn, last edition 1992-11; makers (KIPP, Ganter / JW Winco, OPAC, Blohm) still sell parts to the DIN 172 dimensions. Same bores, OD and lengths as DIN 179 (headless), plus the collar d3 × l2. d3 is d2 + 3 mm up to d2 = 15 and d2 + 4 mm from d2 = 18, on every row.
- Fits: bore d1 F7, OD d2 n6; the receiving hole is H7 (Ganter / JW Winco: 'holes with tolerance H7 are recommended for installing the bushings').
- Where the sources agree: d2, d3, l2 and the short and long lengths on every row from 0.9 mm up (KIPP K1022 and OPAC 479); OPAC also has two rows above 48 mm (d2 70 / d3 74 and d2 78 / d3 82, collar 6) and KIPP a first row 0.4 to 0.8. A Ganter sample row (DIN 172 A 5.1 x 10: d2 10, d3 13, l2 3) and one ehorst listing (bore 7.5, d2 12, d3 15, length 20, collar 3) match. KIPP's third length is its 'long'; OPAC has two lengths (see the DIN 179 page). KIPP prints R and two tolerance columns T1 / T2 without defining them; R is shown, T1 and T2 are left out.
- No file: none of the sheets read says whether l1 counts the collar (the ehorst and damencnc listings give 'length' only). Since the shape depends on it, no body is drawn. For a counterbored collar pocket, d3 is the collar diameter and l2 the collar height; the pocket is your design.
- The ANSI inch equivalent with the head is on the ASME B94.33 page; both there and here the head is a straight disc.

## Mating features (exact size; open press / slide / run / socket by your process clearance, leave designed and clamp as drawn)

| feature | exact | mates with | fit | files |
|---|---|---|---|---|
| OD d2 (n6) | Ø3 to Ø78 by row (10 for a 5.1 to 6 bore, 15 for 8.1 to 10) | plate bore Ø d2 to H7 (Ganter / JW Winco: H7 recommended) | press | all |
| bore d1 (F7) | any size inside the bore range of the row | the drill or reamer of the same diameter (ground F7 guide fit) | slide | all |
| collar d3 × l2 | collar Ø d3 (d2 + 3 or + 4) × l2 high, per row | a counterbore of Ø d3 and depth l2 if the collar is to sit flush; otherwise it seats on the plate face | designed | all |

## Questions

**What is the collar size of a DIN 172 drill bushing with a 6 mm bore?**

OD 10 mm, collar Ø13 × 3 mm high (bore range 5.1 to 6.0), lengths 10 / 16 (and 20 in KIPP's table).

**Is DIN 172 the one with or without the collar?**

With: DIN 172 is the headed (collar) bushing, DIN 179 the plain one.

**What hole does a DIN 172 bushing press into?**

A Ø d2 hole to H7 (the bushing OD is n6); a counterbore of Ø d3 for the collar if you want it flush.
