Wastage vs addition, named exactly
Shaping changes a material's form two ways. Wastage cuts material AWAY -- snips, saws, files, planes, chisels, gouges, rasps, abrasives, the lathe -- which is what almost every tool here does. Addition builds a shape UP by joining or adding material (laminating, fabricating, 3D printing). The mark goes to the specific named tool and the job it does -- a coping saw for curves, a half-round file for a concave edge -- not a vague "cutting tool".
The four bored holes by purpose
Boring marks each hole by what it is for. A pilot hole is small, drilled first to guide a screw or drill so it runs true. A clearance hole is wider than the screw shank, so the screw passes through the top piece freely and grips only the one below, clamping them. A countersunk hole is a cone recess for a flush cone head; a counterbored hole a flat-bottomed recess for a cylindrical head below the surface. Threads need a tapping-size hole.
Threading and turning -- tap, die, lathe
Two wastage processes make threads and round forms. A tap cuts a thread INSIDE a drilled tapping-size hole (internal, like a nut's); a die cuts one on the OUTSIDE of a round bar (external, like a bolt's). On a lathe the workpiece rotates against a fixed tool to make a round form: a centre lathe turns metal, a wood lathe wood. A close-grained wood such as beech turns cleanly because its fine, even grain cuts without tearing; coarse grain splinters.

Defaulting to the laser cutter
A standing examiner key message: centres drill one answer -- "laser cutter" -- and give it for tasks it cannot do. A laser cuts flat sheet along a profile; it cannot bore a counterbore, cut a thread or turn a cylinder. The marks go to the correct named hand tool or process. Match a tool to what the task needs; use CAM only where it genuinely suits the job.
Flagged s23 P32/P33 (standing key message on laser-cutter over-dependence).
Enclosed cut with no drilled hole
To cut an aperture inside a panel you must drill a hole in the waste, thread the saw blade through it, then saw round the line. Candidates forget the starter hole, or name a saw that cannot make an enclosed cut -- a band saw or tenon saw only cuts from an edge. Use a coping, fret or abrafile blade threaded through the hole. The mark is the method plus the saw.
Flagged s23 P32 Q6; w23 P31 Q13a (internal cut needs a hole drilled first; a band saw cannot).
Vague file names score nothing
File and tool names must be exact. "Curved" or "rounded" is rejected -- the answer is a half-round file (for a concave edge) or a round/rat-tail file. A hand file has one "safe edge" (an uncut edge that will not mark an adjacent surface). Examiners reject imprecise names -- learn each file by its full name and job, not by its shape.
Flagged s23 P32 Q13b; w23 P32 Q6 ("curved"/"rounded" rejected for half-round/rat-tail/hand file).
Pilot hole vs clearance hole
These two holes do opposite jobs. A pilot hole is small -- it starts and guides a screw or drill so it runs true and does not split the material. A clearance hole is wider than the screw shank, so the screw slides through the top piece without gripping and the thread bites only in the piece below, clamping the two. Neither is a tapping-size hole.
File vs rasp -- fine vs coarse
A file and a rasp are not the same tool. A file has fine teeth: it smooths and finishes an edge, removing small amounts of material. A rasp has coarse teeth: it removes wood fast and rough for quick shaping, and leaves a surface that must then be filed and abraded smooth. Using a rasp to finish, or a file for bulk removal, wastes time and loses accuracy.
Wastage vs addition (cut vs build up)
The two families of shaping are opposites. Wastage removes material to leave the shape -- sawing, filing, planing, chiselling, turning. Addition builds a shape up by joining or adding material -- laminating, fabricating, 3D printing. A question asking for an addition method scores nothing for a saw or file. Read which family the task needs first.
Tap cuts inside, die cuts outside
A sharp, testable error is swapping the threading tools -- fix it by where the thread ends up. A tap goes into a drilled hole and cuts a thread on the INSIDE (internal, like a nut's). A die closes around a round bar and cuts one on the OUTSIDE (external, like a bolt's). Hook: a tap taps into a hole, a die goes over the bar. The tap needs a tapping-size hole first.
Countersink vs counterbore
A common belief is that a counterbore is just a deeper countersink. They are different shapes for different heads. Countersinking cuts a cone recess for a cone (countersunk) head, so it sits flush. Counterboring cuts a flat-bottomed recess so a cylindrical or bolt head sits below the surface and can be plugged. A cone head will not sit in a flat counterbore.
Name the tool, say what it does, link it
Shaping marks reward a chain, not one word: name the exact tool (coping saw, half-round file, plane), say what it does ("a coping saw cuts curves as its thin blade turns"), and for higher marks link it to this material and task. Stopping at the tool name leaves marks behind.
Match depth to the command word
Match your depth to the command word. Describe wants the ordered method. Explain wants why the tool or step is chosen. Evaluate wants a judgement weighing hand tools against a power or CAM alternative. A sequence given when a reason is asked for caps the mark.
State a process in the right order
Process questions reward the right sequence. Internal cut: mark out, drill the starter hole first, thread a coping blade, saw the line, file. Tapped thread: drill the tapping-size hole, start the tap square, back off to clear swarf. Dropping a step loses the marks.
