Morticing Chisels Introduction
Sharpening chisels for morticing machines doesn’t get much
easier than this. Fit the multi- flute conical reamer with the
appropriate size pilot piece, just a few turns removes a tiny
amount of metal from the chisel’s internal bevel. Using the fine
diamond honing stone included with the kit, touches up the
outer faces of the chisel by removing any burrs thrown up by
the reamer, it’s as simple as that. A sharp chisel cuts cleaner and
Types of Chisel
The Japanese pattern has a point on the end
of the bit and one cutting spur and spiral for
rapid chip clearance. The single spur is easy to
sharpen and cuts evenly and fast, even in the
hardest of timbers.
Whatever the choice, the chisels need to be
installed carefully if good results are to be
achieved.
Installation
The chisel needs to be installed square to the
back fence. The other important adjustment
is to get the correct clearance between the cutting edge of the
auger and the conical recess in the base of the chisel; this will
ensure that there is both sufficient support for the auger in the
chisel and adequate space for chip clearance. One convenient
way to achieve this is to install in position with a spacer (such as
a two pence coin) between the collar of the chisel and the
locating face on the machine, then bring the bit up so that the
cutting part is hard against the base of the chisel and then
tighten up the shank of the bit in the chuck. The spacer is then
removed, the chisel moved up to its correct position and
re-tightened.
Sharpening
Sharpening of the cutting spur is best achieved with a flat
needle file whilst the chisels are best sharpened with the special
piloted reamers.
Morticing Chisel Sharpening Set
is far less prone to burning and, of course, puts far less strain on
the morticing machine. It leaves the internal faces of the mortice
smoother and cleaner making for a better fitting joint. This
Axminster mortice chisel sharpening kit will fit most Taiwanese
and Japanese mortice chisels metric and imperial sizes up to
12mm/1/2”. N.B. Touch up the chisels auger at the same time
using a simple triangular needle or saw file.
Diamond Cone Mortice Chisel Sharpener
Sharpening a mortice chisel significantly improves performance.
We can recommend this pair of specially made diamond coated
cones for most Taiwanese and Japanese mortice chisels, and
Veritas square hole punches. A coarse grit cone gives an initial
grind, followed by a finer honing cone to create a sharp even
edge.
