DW734 · M2 HSS · 3 knives
FOXBC FOX7342, 12-1/2 in HSS knives for DW734, set of 3
The DW734 set, sold explicitly as costing less than having the old ones sharpened.
Every figure below names its source. Each one is a manufacturer
specification read off the listing itself. The judgments are ours.
Cheaper than sharpening
The only listing on either half of this shelf to make the comparison, and it is
the right one to make.
Sharpening a planer knife means grinding a long thin edge dead straight and
parallel. That is a jig-and-surface-grinder job, not a bench-stone one — so it
goes to a service, with postage both ways and a week without a planer.
Three knives with six edges between them cover a great deal of board.
What the listing does not give is how many meters an edge lasts, which is the
figure that would settle it properly.
A planer knife is bought by its section, not by its machine name.
Length sets which cutterhead it spans. Width sets how far it projects past the
clamping bar. Thickness sets whether the clamp closes on it at all. A knife an
eighth of an inch too long will not seat; one a tenth of a millimeter too thick
will not clamp.
Which is why the machine list on a listing is a convenience and the three
dimensions are the specification — and why two listings on this shelf for the same
DeWalt part publish two different lengths.
And this page gives one of the three
Twelve and a half inches of length. No width. No thickness.
The same maker publishes all three on its DW735 listing on this shelf.
Naming the DeWalt part it replaces is a useful shortcut and not the same thing:
part numbers are reused and superseded, and dimensions are not.
No locator holes stated
Which the same maker publishes on two of its other listings here.
Whether the DW734 cutterhead has pins at all is a different question, and this
page does not answer it. What it means for a buyer is that the setting method is
unknown until the cover comes off.
Reversable, in quotation marks
The listing publishes: double-edged “reversable” high-speed steel construction.
The word is in quotation marks and spelled with an a. Both are above as they
stand.
What it means is not in doubt: an edge on each long side, so a dull knife is
unbolted, turned round and refitted.
