reamer
C1/C2Technical/Industrial; Specialised (woodworking, metalworking, culinary); Potentially Historical/Literary for informal/slang senses.
Definition
Meaning
A rotating cutting tool with a spiral or straight fluted head, used for enlarging, shaping, or finishing holes in material such as wood or metal.
Informally, can refer to a device or person that extracts the contents of something (e.g., a citrus reamer for juicing fruit). Historically, slang for a cheat or swindler (19th-century). The verb 'to ream' is unrelated (meaning to enlarge a hole or to reprimand).
Linguistics
Semantic Notes
Primary use is technical. The culinary tool sense is a functional extension of the core concept (a device for boring/extracting). The historical slang is now obsolete. The verb 'ream' (to enlarge with a reamer) exists but is far less common than the noun.

Learning
Memory Aids
Mnemonic
Think: A 'REAMer' helps you get more from a hole, like turning a small REAM of paper into a bigger one (ream = 500 sheets, historically). It expands the hole.
Conceptual Metaphor
A tool is an extension of the body (it performs a precise manual function). Precision is control (the reamer allows exact, controlled enlargement).

Common Pitfalls
Translation Traps (for Russian speakers)
- Не путать с 'ример' (rimmer) – это разное. 'Reamer' не имеет отношения к 'ream' как 'кипа бумаги' в данном техническом значении.
- Прямого однословного эквивалента может не быть; часто переводится описательно: 'развёртка', 'ример' (для труб), 'соковыжималка для цитрусовых'.
Common Mistakes
- Misspelling as 'reamar' or 'reemer'.
- Confusing the tool 'reamer' with the action 'to ream out' someone (to reprimand).
- Using it as a general synonym for 'drill' (a drill makes the initial hole; a reamer perfects an existing hole).

FAQ
Frequently Asked Questions
No. A drill bit creates a new hole. A reamer is used after drilling to slightly enlarge, smooth, or precisely shape an existing hole to an exact size.
Yes, but less commonly. 'To ream' means to enlarge or shape a hole using a reamer. It is a technical verb (e.g., 'ream the bore'). Do not confuse it with the informal verb 'to ream (someone) out' meaning to reprimand.
Outside technical workshops, it is most commonly encountered as a 'citrus reamer' or 'lemon reamer' – a kitchen tool for extracting juice from lemons, limes, etc.
Etymologically, yes, but the connection is very old and not apparent in modern usage. Both derive from Old French 'raime' (a bundle), but their meanings have diverged completely.
