Free power tool accessory diagrams (CC BY 4.0)

This library holds every diagram drawn for AccessoryFit's guides: shank types, saw arbors and bores, sanding disc hole patterns, grinder wheels, grit systems, drill and router bits, and the checks that decide whether an accessory fits a tool. Each one can be downloaded as a WebP image, and most as an editable SVG. All are free to use, adapt and republish under CC BY 4.0, including commercially, with credit to AccessoryFit and a link to this page.

How do you use a diagram from the library?

Find the diagram below, download it, and paste the credit line shown under it. Each entry has a WebP download at full width and, where one exists, an SVG you can recolour, relabel or translate. The Used in link opens the guide the diagram was drawn for, which carries the measurements and sources behind it. Open Credit line to copy under any image for an HTML snippet that names AccessoryFit, links back to that diagram and names the licence.

Credit line for any diagram: Diagram: <a href="https://accessoryfit.com/diagrams/#ID">AccessoryFit</a>, <a href="https://creativecommons.org/licenses/by/4.0/">CC BY 4.0</a>. The button under each diagram copies it with the right link filled in.

What do the diagrams cover?

The diagrams explain how accessories attach to tools and what the markings on them mean. They fall into a handful of groups.

  • Shanks and holders: SDS-plus and SDS-max shanks, hex driver bits, jigsaw T-shank and U-shank ends, reciprocating saw and oscillating tool mounts, drill chuck capacity and router collets.
  • Saw blades: blade diameter and bore as separate checks, the diamond knockout, kerf and plate thickness, tooth-top shapes, band saw blade dimensions and tooth spacing, and miter and table saw fit.
  • Discs and abrasives: sanding disc hole patterns and dust paths, mesh and punched discs, detail sander pads, flap discs, flat and depressed-centre grinding wheels, cut-off wheels and wheel speed ratings.
  • Grits and sizes: CAMI and FEPA grit grading, how to read drill size, tap drill and pilot hole charts, and hole saw sizing.
  • Bits and cutting forms: twist, masonry, tile, step, Forstner, spade and auger bits, and router bit profiles and bearings.
  • Fault-finding: grinder vibration, blade burning, drill bits walking, recip blades breaking, router chatter and sander swirl marks.

A few diagrams explain how AccessoryFit itself works, such as how a specification is traced back to its source; these are free to reuse too. To see the topics in more depth, start with the compatibility guides for fit questions or the technique guides for choosing and using accessories.

What does the CC BY 4.0 licence let you do?

Creative Commons Attribution 4.0 lets you copy, share, adapt and republish the diagrams in any medium, for any purpose, including commercial use, without asking first. The one condition is attribution: credit AccessoryFit, link to https://accessoryfit.com/diagrams/ (or the diagram's own anchor on this page), name the licence, and say if you changed the image. You may not suggest that AccessoryFit endorses you or your product.

That covers blog posts, product listings, training slides, school worksheets, printed manuals and books. If you redraw a diagram from scratch in your own style, crediting it as based on the AccessoryFit diagram is still appreciated.

How should you credit a diagram?

Use the credit line under the image you take, which is already formatted with the right links. On a web page it reads: Diagram: AccessoryFit, CC BY 4.0, with AccessoryFit linked to the diagram on this page and CC BY 4.0 linked to the licence. In print, where links do not work, write the address out: Diagram: AccessoryFit (accessoryfit.com/diagrams/), CC BY 4.0. If you edited the diagram, add adapted, as in Diagram adapted from AccessoryFit.

Put the credit next to the image or in a figure caption rather than only in a page footer, so it stays with the diagram when your page is quoted or shared.

How accurate are the diagrams?

The diagrams are conceptual illustrations, not manufacturing drawings, and they are not drawn to scale. They show which parts and dimensions matter and how they relate, for example that a blade's bore and its diameter are two separate checks. The actual sizes, speeds and tolerances are on the linked guides, where every figure comes from a manufacturer specification or standard and is listed under References. Before cutting, drilling or fitting anything, check the markings on the accessory and the tool's manual.

The editorial process behind the guides and their figures is set out in the AccessoryFit methodology, and the site's data and statistics pages are collected under AccessoryFit research.

Can you request a new diagram?

Yes. If there is an accessory interface, marking or size system you need explained and it isn't in the library, send a request through the contact page. Say what the diagram should show and where you plan to use it. Requests that fill a gap in an existing guide are the most likely to be drawn, and new diagrams are added to this page under the same licence. The same form is the place to report a diagram that looks wrong.

Questions readers ask

Can I use AccessoryFit diagrams on a commercial website?

Yes. CC BY 4.0 allows commercial use, including on shop pages and product listings, as long as you credit AccessoryFit with a link to this page and name the licence.

Can I edit the SVG files?

Yes. You may recolour, relabel, translate or crop them. Credit the original to AccessoryFit and say it has been adapted.

Are the diagrams drawn to scale?

No. They are conceptual illustrations of how parts relate. For real dimensions use the guide each diagram links to, or the accessory and tool manufacturer's own data.

Do I need to ask permission before using a diagram?

No. The licence already grants permission. Attribution is the only requirement, and a note through the contact page telling us where it appears is welcome but optional.
