Hand reamers are designed to be rotated clockwise during operation. This is crucial because the geometry and cutting action of the reamers are specifically engineered for this direction. The cutting edges of a hand reamer are typically angled to facilitate cutting efficiently only when turned clockwise.

When using a hand reamer, it's important to apply steady pressure and maintain alignment to achieve a smooth, precise finish in the hole being reamed. Rotating the tool in the correct direction enables the cutting edges to engage the material properly, allowing for effective removal of metal and precise sizing of the hole.

Although there are instances where other tools may operate effectively in varied directions, hand reamers are unequivocally intended for clockwise rotation to ensure optimal performance and maintain tool integrity. Understanding how hand reamers function within this context is essential for inexperienced users to avoid damaging the tool or producing inferior work results.
