Adjustable reamer - manual - without guide bush Range: according to the chosen variant Standard: without standard, replacement for ČSN 221424 Manual adjustable reamers are ONLY suitable for through holes. The cutting edges ream gradually (conical hole), ie the set diameter will not be reamed until the reamer passes the cutting edges through the hole. Adjustable reamers are used in finishing machining operations with cylindrical holes. Reamed holes have a precise size, geometric shape and a smooth surface. The size of the reamer is continuously variable within the specified range. The set size is measured via a pair of opposing knives. The commonly supplied knife geometry is suitable for machining gray cast iron and bronze.

Adjustable reamer without guide / bet guide sleeve, ČSN 221424 Scope: according to the selected variant Dimensions: see product description for individual variants or see attached catalog sheet Standard: ČSN 221424 Hand adjustable reamers are ONLY suitable for through holes. The blades are reamed gradually (conical hole), i.e. the set diameter will only be reamed when the reamer passes through the blades. Adjustable reamers are used in finishing machining operations of cylindrical holes. Reamed holes have an exact size, geometric shape and a smooth surface. The size of the reamer is continuously variable within the specified range. The set dimension is measured over a pair of opposing knives. The commonly supplied blade geometry is suitable for machining gray cast iron and bronze.
