Bandsaw Blades

Tool-default.png
Synonyms: band saw blades, saw bands, band blades;
DE: Bandsägeblätter, Sägebänder
Material: various (see list)
Used with: bandsaws
Location: wood workshop (above bandsaw)
Access Requirements: bandsaw introduction
Tutors: same as for bandsaws
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:

ID Status Tooth Pitch (Zahnteilung) Zahnweite Width Kerf Min. Radius [3] Tooth Shape Materials Comments
OK 6 TPI Z4 13 mm approx. 100 mm hook wood, acrylic glass Metabo original
6 TPI Z4 8 mm hook wood, acrylic glass
broken, re-ordered 4 TPI Z6 10 mm 40 mm hook wood steel type "GBLADEunicut41C", from Maschinenhandel Meyer: "Bandsägeblatt 10 x 0,5 mm - für kleine Bandsägen"
broken, re-ordered 3 TPI Z9 ("Z9+") 15 mm 95 mm hook wood suitable for up to 350 mm high pieces (resawing!), steel type "GBLADEwoodcutUHB15+", from Maschinenhandel Meyer: "Bandsägeblatt 15 x 0,5 mm"
gone 3 TPI "3Z" 16 mm 95 mm(?) hook wood source unclear, did not perform as well as the 15 mm, 3 TPI blade
uncertain 6 TPI Z4 13 mm hook wood, acrylic glass duplicate entry?
More needs to be documented! Any help would be most 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
