Starter set · 15 bits
KOWOOD 15-piece set, 1/4 in shank
Fifteen bits in a wooden case, on five bullets shared word for word with the maker's 24-piece set.
Every figure below names its source. Each one is a manufacturer
specification read off the listing itself. The judgments are ours.
Fifteen bits, none named
A wooden case, a mention of tongue and groove, and fifteen.
That is the contents list.
The published ENT 12-piece set on the European half of this shelf has the same
gap, and its page makes the honest case for buying one regardless: a useful way
to discover which profiles you actually need, and sets are priced by quantity —
the profiles you never use subsidize the four you do.
That argument holds here. The gap is still a gap.
The same five bullets as the 24-piece
Word for word, in the same order, with the same punctuation. Only the count in
the last line changes.
So nothing on either page distinguishes the two sets except a number, and neither
names a bit.
The only decision available is fifteen or twenty-four.
Shank before everything
A router bit is held by its shank, and the collet that holds it has one size.
A quarter of an inch is 6.35 mm (0.25 in). Eight millimeters is eight. A 1/4 in bit drops
loose in an 8 mm (0.31 in) collet and an 8 mm (0.31 in) bit will not enter a 1/4 in one — and a
collet is a precision clamp, not a hole: there is no ring, no bush and no adapter
that makes either fit the other safely.
Which is why the two halves of this shelf cannot be mixed. Every American listing
here is 1/4 in; every European one is 8 mm (0.31 in). The published Spetool page on this
shelf states the rule in one line, and it is the most useful sentence on the
shelf.
Anti-kickback
The only geometry claim on either half of this shelf, and it is a real one.
The steel behind each carbide tip is left standing almost level with the cutting
edge, so the chip thickness is limited by the body rather than by how hard the
wood is pushed.
Which is what stops a bit grabbing and snatching the work out of the hands. It
is standard on better bits and worth having named.
And it says what it will not cut
Stated: do not cut ferrous metal and non wood.
Across fourteen listings on this shelf, two state a limit of any kind. The other
is the published dovetail cutter on the European half, whose page records the
opposite problem — its maker names stainless, carbon steel, cast iron and tool
steel, and not timber.
