Ordering & dimensions

Monoblock reamers, Ø5.5 to 23.50 mm H7. Build a valid order code from the printed tables, or read the dimensions straight off them.

Build a code

Five inputs, one order code

Every code Reamtech quotes is assembled the same way — the base code carries construction, series length, and hole type; the diameter is encoded as Ø × 1000; the suffix is the grade for your material.

Order code builder

The catalogue’s rule is Order Code + Diameter + Grade. Set the five inputs and the code resolves, along with the dimensions for that Ø band.

Dimension tables

Nine diameter bands, short and long series, for both constructions. The solid monoblock dimensions match size adjustable at the same series length — only the order code differs.
