Multi-blade reamers for superior quality bores and process stability.

The proven geometries of DIATOOL reamers produce precision bores at much higher feed rates than single-point tools – reducing cycle time and total cost of ownership.

A German-crafted plug & play solution in consistently short lead times.

Advantages

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

Available Reamer Options

Mono-block Reamers

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

  • Solid and expandable Ø 5,600 – 60,599 mm (on request up to Ø 100,599 mm)
  • With and without internal coolant supply
  • Short and long version
  • Available for many different cutting materials and coatings
  • Wear compensation through an easy-to-use expansion feature.

Cutting Ring Reamers

Cutting rings offer an expandable modular design for larger hole diameters and are interchangeable with major European brands. Compensation for wear is made by turning an expansion nut on the mounting arbor. DIATOOL also offers a unique solid (non-expandable) cutting ring when expansion is not necessary and with the added option of left hand helix.

  • Modular cutting rings Ø 50,600 – 150,599 mm
  • Solid and expandable, left hand and straight fluted
  • Different cutting materials and coatings
  • Simple and precision changeability
  • Holders with internal coolant supply
  • Short and long holder version
  • Easy-to-use expansion feature

Reaming Head Reamers

Rapid-set reaming heads are available as a non-expandable, modular option. Reaming heads are interchangeable with the major European brands.

  • Modular reaming heads Ø 9,600 – 60,000 mm
  • Different cutting materials and coatings
  • Modular reaming system without diameter setting required.
  • Simple, fast and precision changeability
  • Holders with internal coolant supply
  • Short and long holder version
