My new Makita jigsaw came with a variety of blades and I also just bought
some L-10 which are 155mm long for a job later this week. They came with
yet more Makita blades.
I'm trying to make sense of what does what. Found Lawsons site, which was
some help & copied a table into an Excel spreadsheet involving much deleting
Length, material, no of teeth all make sense.
What puzzles me is that they have blades in Type A, B, C & D. This seems to
refer to the set and grinding angle of the teeth.
Anyone know what the code letters mean?
Hmmm.... Why do Bosch make a jigsaw that's supposed to have a135mm
capacity, but you have to buy Makita blades to get ones long enough to
I don't know Lawsons', but aren't their Bosch part numbers all a few
IMHO, go with Bosch blades for indoor work. Their taper ground blades
give a better finish than Makita blades. The "swiss army knife" tooth
shape (each tooth is prominently triangular in plan, not chisel shaped)
of the T301 seris blades gives a particularly good finish on typical
man-made woodish boards in kitchens. They're as good as a reverse-cut
blade, but easier to control.
For outdoor stuff and carpentry, Makita have better tooth profiles for
aggressive cuts, particularly for fast cuts in softwood. Bosch don't
make a 4mm pitch blade with anything like enough gullet space to clear
softwood chips, so use the Makita B12 instead. The Bosch Progressors
are particularly bad here -- the big 4mm pitch one (T345) is equally
useless at everything
Supposedly the Makita hollow ground gives less kerf friction than a
taper grind, but the numbers just don't add up for a blade this narrow.
Snake oil, IMHO.
The Bosch "cheap and cheerful" yellow set-rather-than-ground blades
(T111 and T119) series aren't much good for anything, and they steer
badly. Best avoided - decent ones don't cost that much more.
If you want to understand tooth profiles, read something on bandsaws -
like Duginske's book.
