Kennametal RMB Multiflute Reamers

RMB™ Multiflute Reaming

The RMB Multiflute Reaming System achieves solid carbide and solid cermet metal removal rates from 14–20mm with no customisation required. All standard reamers are ground to an ISO H7 tolerance class hole to address most applications, giving you an economical solution for large diameter sizes compared to solid carbide reamers. Specific coatings and lead configurations enable high-speed machining of steel, stainless steel, cast iron, and non-ferrous materials at accelerated speeds.

Primary Application

Use SIF™ Steerable Hydraulic Chucks or SIF Adaptors for easy compensation of radial runout and angular inaccuracies of the spindle to achieve the highest possible hole straightness and surface quality.

Features and Benefits

Higher Productivity and Profitability

Longer tool life with increased hole and surface quality due to lapped ground leads.
Highest metal removal rate at higher speeds and feeds due to reaming specific grades and substrates.
Improved straightness and cylindrical form compared to competitive tools and reduced vibration tendency due to unequal flutes.
Adjustment screw at straight-fluted RMB reamers to change internal coolant supply from axial to radial.

Customisation

Diameters up to 50mm available with and without internal coolant in 0,001mm steps.
Intermediate diameters of standard program available as Simple Specials with short delivery time.
RMB tooling for machining heat-resistant materials is available on request.
