How to say "grinder" in Japanese

• グラインダー
  nounA powered grinding tool or machine, the kind used in metalwork and construction to grind down metal or stone; this loanword is what you want for a handheld or bench power tool.
• ミル
  nounA mill — a device with a grinding mechanism for foodstuffs such as coffee beans or peppercorns; use it when English 'grinder' refers to one of these kitchen or table mills.
  飲のむ分ぶんだけ豆まめをローストして、ミルで挽ひくんです。↗

  We roast just enough beans for the amount we're going to drink, and grind them in the coffee mill.
• 圧砕機あっさいき
  nounReally a crusher: industrial machinery that breaks material down by crushing or pulverizing it under pressure. For most senses of 'grinder' this is not the word you want.
• 研削盤けんさくばん
  nounA stationary machine-tool grinder: workshop equipment that finishes metal workpieces with an abrasive wheel to exact dimensions. Use it for the industrial 'grinding machine', not for handheld power tools.
• 研磨機けんまき
  nounA general term for abrasive finishing machines, covering grinders and polishers alike; choose it when the machine grinds, sands, or polishes a surface, as in metal finishing or floor maintenance.

Choose 「グラインダー」 for a powered grinding tool, 「ミル」 for a mill that grinds food, 研削盤 for a stationary machine-tool grinder, 研磨機 for machines that grind or polish, and 圧砕機 only for crushing machinery.
