Right-hand cutting reamer with expanding blades.
Due to the unique Hunger relief grinding operation the blades have a progressively increasing clearance angle giving a soft cutting action.
Starting with size D 12 the adjusting nut is marked with an annular scale. One graduation of the scale corresponds to a change of the reamer diameter by 0,01 mm.
The reamers are fitted with blades made of high quality special steel to ensure superior cutting performance.
The production of reamers with hard chromium coated blades and of hard chromium coated replacement blades has been discontinued.
Remainders of stock are available as long as stock last.
