Expandable Reamers increase tool life and reduce downtime.
Press Release Summary:
Respectively available in 14–20 mm and 14–42 mm dia, RMB-E™ monobloc and RHM-E™ modular reamers operate with rotation wrench that offers linear expansion of 2 microns for every 30° turned. Tools support expansion to 3X IT6 tolerance class, increasing tool life by up to 300%, while elastic expansion within steel body and failsafe runstop design (after 2 complete revolutions) ensure tool is not damaged. Expansion may be reversed, and straight and helical fluted geometries are available.
Original Press Release:
Innovative RMB-E and RHM-E Expandable Reamers Increase Tool Life by up to 300%, Significantly Reduce Downtime
LATROBE, Pa. — Kennametal introduces a new line of innovative, expandable, high-performance reamers that increase tool life by up to 300% and significantly reduce downtime. RMB-E™ monobloc and RHM-E™ modular reamers are one-of-a-kind, accurate, and easy-to-use expansion tools.
Both RMB-E and RHM-E expandable reamers operate with a rotation wrench that offers a predictable linear expansion of 2µ for every 30° turned. This means that no adjustment measurements are required and the tool does not need to be removed from the machine during the expansion process. The simple adjustment process also requires less training and eliminates manual calibration, making it easier to expand tool sizes and dramatically reduces downtime.
These expansion platforms are capable of a large expansion range of up to three times IT6 tolerance class, increasing tool life by up to 300%. The elastic expansion within the steel body, along with its proprietary, failsafe runstop design after two complete revolutions, ensures the tool is not damaged. This expansion system also allows the user to reverse any expansion in case the tool has been expanded too much or if a smaller expansion is needed.
The RMB-E and RHM-E platforms are both offered with internal through coolant capabilities and are available in two geometries: straight fluted for machining blind holes and helical fluted for through holes. Kennametal is offering these products in two different grades. KC6305™ is for multipurpose applications, and KC6005™ is engineered especially for cast iron. Further cutting, such as cermets, PCD, or CBN materials, will be available as custom solutions. All of these grades provide superior wear resistance and outstanding frictional properties for longer tool life and good surface quality. RHM-E reamers are available in diameters ranging from 14–42mm, while RMB-E diameters range from 14–20mm.
