Standaard boormaten
Bij het ontwerpen van boorgaten is het het beste om de standaard boormaten aan te houden. De onderstaande referentietabel helpt jou te begrijpen wat als een standaardboor wordt beschouwd, van de kleinste naar de grootste. Voor gaten buiten dit bereik kan speciaal gereedschap nodig zijn.
Maten op imperiale boorkits worden meestal aangeduid met cijfers of letters. Metrische boor laten we meestal gewoon de daadwerkelijke meting gebruiken. De onderstaande grafiek met vier kolommen is een handige kruisverwijzing voor boorbits.
