FAQ's: Reamers
How do you maintain a reamer?
Keep it sharp, avoid forcing it, use proper lubrication, and store it in protective sleeves to prevent edge damage.
What’s the difference between a chucking reamer and a construction reamer?
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.
How do I choose the right reamer size?
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.
What coatings are available for reamers?
Common coatings include black oxide for rust resistance, TiN (titanium nitride) for wear resistance, and uncoated for general use.
Do reamers need lubrication?
Yes — cutting fluid or lubricant extends tool life, improves finish, and helps with chip removal.
What is the tolerance of a reamed hole?
Reamed holes can achieve tight tolerances, often within ±0.001" depending on the tool and setup.
Can I use a reamer in a hand drill?
Yes for some types, like construction or bridge reamers with hex shanks, but precision reaming is usually done in drill presses or milling machines.
Do reamers come in different shank types?
Yes — including straight shank, tapered shank, and hex shank to fit different drills, reaming machines, and impact wrenches.
Can a reamer drill a hole from scratch?
No. Reamers are for existing holes — the hole must be pre-drilled undersize before reaming.
What materials can reamers cut?
Steel, stainless steel, cast iron, aluminum, brass, and other metals — with the right material and coating for the job.
When should I use a bridge reamer instead of a construction reamer?
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.
What’s the advantage of spiral flutes over straight flutes?
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.
What is a spiral flute reamer?
A reamer with helical flutes designed to cut more smoothly, evacuate chips better, and work well in holes with interruptions or cross-drilled features.
What is a construction reamer?
A heavy-duty reamer designed for enlarging or aligning structural steel holes during construction work, often used in fabrication and field assembly.
What is the difference between a drill bit and a reamer?
A drill bit removes material to create a hole; a reamer refines an existing hole’s size, alignment, and finish.
What is a reamer used for?
A reamer is a precision tool used to enlarge, align, or finish an existing hole to an exact size with a smooth surface finish.
