Translate 'burr' to German.

The translation of 'burr' to German as 'Grat' is accurate because 'Grat' specifically refers to a rough or uneven edge or protrusion that is left on a material after machining or cutting. In technical contexts, this term is widely used to describe the unwanted remnants created on materials like metal or wood that need to be removed to ensure a smooth finish.

Other terms listed do not match the definition of 'burr.' For example, while 'Bolzen' refers to a bolt, 'Scheuern' translates to 'to rub' or 'to scrub,' and 'Verbrauchsmaterial' means 'consumable materials.' These translations pertain to distinct meanings and contexts that do not relate to the concept of a burr. Thus, 'Grat' is the most relevant and precise translation for 'burr' in technical language.
