Drill bushings DIN 172 (headed, with collar): bore range, OD n6, collar diameter and height, lengths, 0.4 to 63 mm — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/drill-bushings-din-172-headed/ (sheet CC BY 4.0) Basis: KIPP data sheet K1022 and OPAC's DIN 172 table (agree), DIN Media for the standard's title, Ganter / JW Winco for the fits; McMaster-Carr linked for CAD Catalog version: 2026-10-20 Sizes: see table below - 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 DIN Media titles it 'Press fit jig bushes, headed' (Bundbohrbuchsen) and lists it as withdrawn, last edition 1992-11; makers (KIPP, Ganter / JW Winco, OPAC, Blohm) still sell parts to the DIN 172 dimensions.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. bore d1 range, mm (F7) OD d2, mm (n6) collar Ø d3, mm collar height l2, mm l1 short, mm l1 long, mm (KIPP: medium) l1 extra long, mm (KIPP only) R, mm (KIPP, as printed) sources 0.4 – 0.8 3 6 2 6 — — 1 KIPP 0.9 – 1 3 6 2 6 9 — 1 KIPP + OPAC 1.1 – 1.8 4 7 2 6 9 — 1 KIPP + OPAC 1.9 – 2.6 5 8 2 6 9 — 1 KIPP + OPAC 2.7 – 3.3 6 9 2.5 8 12 16 1 KIPP + OPAC 3.4 – 4 7 10 2.5 8 12 16 1 KIPP + OPAC 4.1 – 5 8 11 2.5 8 12 16 1 KIPP + OPAC 5.1 – 6 10 13 3 10 16 20 1.5 KIPP + OPAC 6.1 – 8 12 15 3 10 16 20 1.5 KIPP + OPAC 8.1 – 10 15 18 3 12 20 25 2 KIPP + OPAC 10.1 – 12 18 22 4 12 20 25 2 KIPP + OPAC 12.1 – 15 22 26 4 16 28 36 2 KIPP + OPAC 15.5 – 18 (OPAC: from 15.25) 26 30 4 16 28 36 2 KIPP + OPAC 18.5 – 22 (OPAC: from 18.25) 30 34 5 20 36 45 3 KIPP + OPAC 22.5 – 26 (OPAC: from 22.25) 35 39 5 20 36 45 3 KIPP + OPAC 26.5 – 30 (OPAC: from 26.25) 42 46 5 25 45 56 3 KIPP + OPAC 30.5 – 35 (OPAC: from 30.25) 48 52 5 25 45 56 3 KIPP + OPAC 35.5 – 42 55 59 5 30 56 67 3.5 KIPP + OPAC 42.5 – 48 62 66 6 30 56 67 3.5 KIPP + OPAC 48.5 – 55 70 74 6 30 56 — — OPAC only 56 – 63 78 82 6 35 67 — — OPAC only Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - KIPP (via marek.eu): K1022 drill bushes with collar DIN 172: D1 range, D2, D3, L1 short / medium / long, L2, R, T1, T2 — web — Publisher's page; dimensions are facts — https://www.marek.eu/data/katalogove-listy/kipp/K1022.pdf - OPAC: DIN 172 drill bushes with collar: bore range, OD, collar diameter, collar height, short / long length — web — Publisher's page; dimensions are facts — https://www.opac.net/en/producto-479-din-172 - DIN Media: DIN 172 'Press fit jig bushes, headed' (Bundbohrbuchsen): withdrawn; editions 1953-01 to 1992-11 — web — Publisher's page; dimensions are facts — https://www.dinmedia.de/en/standard/din-172/103715612 - ehorst.de (Ganter DIN 172 A listing): DIN 172 A 7.5 x 12 / 15 x 20, collar 3 mm: bore, OD n6, collar, length, collar thickness; H7 receiving holes recommended — web — Publisher's page; dimensions are facts — https://www.ehorst.de/en/Bundbohrbuchse-DIN-172-A-7-5x12-15x20-mm-Bundstaerke-3-mm-lang-1-0718-carbonitriert-HRC-62-2-1402299.html - McMaster-Carr: Drill bushings (press-fit, headed and plain, inch and metric) (free STEP/IGES per part, for your own design use; no redistribution) — STEP, IGES, PDF — McMaster-Carr site terms: personal design use, no redistribution [verify license at link] — https://www.mcmaster.com/products/drill-bushings/ No true-size file yet: the published figures do not fix the whole shape; a measured scan is planned.
