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.
