MAPAL HPR Replaceable-Head Reamers

The HPR range of replaceable head reamers includes series for through and blind bores from a diameter of 8.00 mm. The replaceable head reamers are available either of fixed design (series 100) or of finely adjustable design (series 200) and can be tipped with different cutting materials such as carbide, cermet, PcBN or PCD.

Key Features

• The HPR range of replaceable head reamers includes series for through and blind bores from a diameter of 8.00 mm.
• The replaceable head reamers are available either of fixed design (series 100) or of finely adjustable design (series 200) and can be tipped with different cutting materials such as carbide, cermet, PcBN or PCD.
• High-performance CVD and PVD coatings increase tool lives and the cost-effectiveness of the reamers.
• The innovative CVD coating HC419 reliably machines the complete range of cast iron materials, with high cutting speeds and maximum productivity.
• ​​​​​​​ The reamers can be configured in the diameter range from 8.00 to 65.00 mm in steps of 0.10 mm; the tolerance range can also be configured.
• A broad range of H7 dimensions is available as a preferred series.
• The related holders with the HFS (Head Fitting System) feature exact radial run-out and changeover accuracy, along with safe and simple handling, particularly during assembly and dismantling of the tool head.
• HFS guarantees high precision and power transmission, here changeover and radial runout accuracies less than 3 μm can be achieved reliably.
• Due to the simple construction with direct coolant supply to the cutting edge, the system is suitable for minimum quantity lubrication (MQL).
