FAQ's: Reamers

Keep it sharp, avoid forcing it, use proper lubrication, and store it in protective sleeves to prevent edge damage.

Chucking reamers are precision tools used in machine setups for fine hole finishing; construction reamers are heavier-duty and used in fabrication environments for enlarging and aligning holes.

Choose a reamer that’s slightly larger than the pre-drilled hole size you need to finish — the hole should be about 0.010"-0.015" smaller than the final reamed size.

Common coatings include black oxide for rust resistance, TiN (titanium nitride) for wear resistance, and uncoated for general use.

Yes — cutting fluid or lubricant extends tool life, improves finish, and helps with chip removal.

Reamed holes can achieve tight tolerances, often within ±0.001" depending on the tool and setup.

Yes for some types, like construction or bridge reamers with hex shanks, but precision reaming is usually done in drill presses or milling machines.

Yes — including straight shank, tapered shank, and hex shank to fit different drills, reaming machines, and impact wrenches.

No. Reamers are for existing holes — the hole must be pre-drilled undersize before reaming.

Steel, stainless steel, cast iron, aluminum, brass, and other metals — with the right material and coating for the job.

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.
