When necessary, the blade can also be rotated with respect to the frame to make sharper curves in the material being cut. Blade breakage is much rarer than with a fretsaw. A coping saw (with the correct blade) can also be used to cut through aluminium tubing and other metal objects, though a hacksaw is much more efficient for this task. The ...
Although the coping saw is often used for similar work, the fretsaw is capable of much tighter radii and more delicate work. It has a distinctive appearance due to the depth of its frame (typically between 10 and 20 inches (25 and 51 cm)), which together with the relatively short five-inch (13 cm) blade makes this tool appear somewhat out of proportion compared with most other saws.
These sleeves are a tool used to hold machine cutting tools or holders in the spindles of machines such as a drill or milling machine. The reamer shown is a finishing reamer. A roughing reamer would have serrations along the flutes to break up the thicker chips produced by the heavier cutting action used for it.

Benchtop drill press (left) and floor-standing drill press (right) A drill press is a drilling machine suitable for quick and easy drilling of straight holes, countersinking or counterboring that are perpendicular to both directions of a table surface. In comparison, it is more difficult and less repeatable to drill perpendicularly with a hand ...
Hacksaw blades are normally quite brittle, so care needs to be taken to prevent brittle fracture of the blade. Early blades were of carbon steel, now termed 'low alloy' blades, and were relatively soft and flexible. They avoided breakage, but also wore out rapidly. Except where cost is a particular concern, this type is now obsolete.
