Solid and Expandable Solutions

Solid And Expandable Mono-Block Reaming

Mono-block reamers are available in both expandable and solid (non-expandable) configuration styles for producing high-quality bores. Compensation for wear can be made by tightening a conical screw in the expandable Mono-block style reamers, while both the solid and expandable styles can be reconditioned for prolonged tool life.

We offer precision mono-block reaming solutions from DIATOOL with options and features including:

  • Solid and expandable Ø 5.600 – 60.599 mm
    (on request up to Ø 100.599 mm)

Advantages of DIATOOL

DIATOOL reamers offer a multi-blade design with unequal spacing of the cutting edges that produces very round and cylindrical bores compared to conventional reamers and at much higher feed rates than single-point tools. 

We offer DIATOOL’s quick turnaround re-tipping to customers with competitor’s products as well. This is a huge advantage for those who do not wish to waste their initial investment but cannot afford the long lead times they are experiencing from DIATOOL’s competitors.
