Saws
Miter saw
A miter is and angled joint[1].
A miter saw (or mitre saw) helps such joints -- and anything else that is served by well controlled angles
Classically this was mechanical:
- miter box
- wood with slits that guide 90 and 45 degree angles
- to use a regular handsaw in
- the most basic thing you could call 'miter saw' is a handsaw guided by a mechanical mount
- (and replacable blade)
- preferable in that miter boxes tend to degrade with use, so this is more reusable and more precise
Power miter saws are the variants that are motorized, mainly:
- standard miter saw
- brings down a saw head, at a controlled angle.
- (a chop saw is this without the angle control, always cutting right, 90 degree angles)
- compound miter saw
- adds tilt of the head
- (sometimes the basic rotation may be a little more aribitrary/controlles than in a basic variant)
Options / details:
- sliding miter saw (on a compound or standard miter saw)
- sawblade extends on a sliding rail, rather than only being brought down
- can deal with somewhat larger boards
- ability to angle to both sides rather than one (and, less commonly, to tilt to both sides)
- easier to do certain cuts readjusting the saw rather repositioning than the workpiece
- LED/laser
- a little more precision
Because this is a collection of features realized in different combinations
- some may be unique to areas (or industries)
- and may have specific names in some areas of the world that they do not have in others.
Circular saw
Sort of like a table saw without a table.
Generally for wood, though variations for e.g. metal and concrete may vary in design, not just mounting a different blade.
