FAQ's: Reamers

Bridge reamers are best when hole misalignment is common — their long taper helps guide and center the reamer quickly. Construction reamers excel at enlarging holes to exact diameters.

Spiral flutes provide a smoother cut, reduce chatter, and are better for reaming in softer or gummy materials, while straight flutes give a rigid cut in harder materials.

A reamer with helical flutes designed to cut more smoothly, evacuate chips better, and work well in holes with interruptions or cross-drilled features.

A heavy-duty reamer designed for enlarging or aligning structural steel holes during construction work, often used in fabrication and field assembly.

A drill bit removes material to create a hole; a reamer refines an existing hole’s size, alignment, and finish.

A reamer is a precision tool used to enlarge, align, or finish an existing hole to an exact size with a smooth surface finish.
