c. Use of reamers.
(a) Use a solid straight hole reamer for most work, since it is the most
accurate and rugged of the straight hole reamers.
(b) When using a taper pin, expansion, or adjustable reamer, a series of
small cuts should be taken rather than one deep cut. Check the hole for size after
each cut to insure that you do not remove too much metal from the hole.
(c) Never force a small reamer into a hole with too much pressure, since
reamers are delicate and easily broken.
(d) Most reamers are hand-driven tools; however, some are power- driven.
