| ToolInfoBox Bandsaw Blades | |
|---|---|
| |
| Synonyms: | band saw blades, saw bands, band blades; DE: Bandsägeblätter, Sägebänder |
| Material: | various (see list) |
| Used with: | bandsaws |
| Location: | wood workshop (currently under the chop saw station - not ideal |
| Access Requirements: | upon personal introduction |
| Tutors: | Lukas |
| Similar (More or Less): | Circular Saw Blades |
A bandsaw's capabilities heavily depend on which blade you choose. This page should let you see what we have in the Space and help you select the proper blade for each project.
Parameters to consider for each use:
- tooth pitch (Zahnteilung): spacing of teeth
- usually expressed as teeth per inch (TPI) or Zähne pro Zoll (ZpZ)
- for wood, 3-5 teeth should be in the cut (thicker workpiece: fewer teeth per inch!) [1]
- alternative notation: Zahnweite, expressed as mm between teeth (e.g. "Z5" = 5 mm from tip to tip)
- width
- determines the minimum radius you can cut (the narrower the blade, the smaller the achievable curves)
- kerf (Schnittbreite): a bit higher than the blade's back thickness because of the teeth's set (Schränkung)
- tooth shape
- greatly influences which materials that can be cut
- carbide tipped blades with a longer lifespan are become more widespread, but are still very expensive [citation needed]
...and to consider when buying blades:
- length: found in the manual
- thickness: should usually not be more than 1 ‰ of the guide wheel diameter or the blade might break [2]
- different for three-wheel saws?

2225 mm Blades
These blades are compatible with our Metabo BS 1638 W. Here's what we have:
| Tooth Pitch (Zahnteilung) | Zahnweite | Width | Kerf | Min. Radius [3] | Tooth Shape | Materials | Comments |
|---|---|---|---|---|---|---|---|
| 6 TPI | Z4 | 13 mm | approx. 100 mm | hook | wood, acrylic glass | ||
| 6 TPI | Z4 | 8 mm | hook | wood, acrylic glass | |||
| 4 TPI | Z6+ (?) | 10 mm | approx. 50 mm | hook | wood | Use with caution - has a bend to the left and needs sharpening! | |
| More | needs | to | be | documented! | Any | help | welcome :-) |
1400 mm Blades
These blades are compatible with our CMI C-S-BS 250. Here's what we have so far:
| Tooth Pitch (Zahnteilung) | Width | Kerf | Min. Radius | Tooth Shape | Materials | Comments |
|---|---|---|---|---|---|---|
| 14 TPI | 6 mm | soft non-ferrous metals (e.g. aluminum, copper, bronze) | ||||
| 6 TPI | 6 mm | hook | wood | may not cut too well - the set (Schränkung) of the teeth seems to have suffered |
