Ø 4.0 - 60.0 H7, Straight/Spiral Flute Cylinder Shank

Righthand cutting, straight flutes, expandable, slotted, with pilot. cyl. shank with square.

The Expandability is due to the limited elasticity of hardened steel and the above-stated approximate values should therefore not be exceeded. Consequently, it is possible to adjust all Þ ts to compensate for wear. The reamers are ground to nominal size and not on the tolerance H7.
Expandability approx. 0.10-0.60 mm.

We carry the full range sizes up to 60mm. Do contact us for quotation above 20mm.
