HSR ™ Carbide- and Cermet-Tipped Reaming Tools
• Achieve solid carbide and solid cermet metal removal rates from 14–32mm (.551–1.26")
with no customisation required.
• Ground to H7 tolerance class to accomodate most applications.
• Specifi c coatings and lead confi guration for high-speed machining of steel, stainless steel,
cast iron, and non-ferrous materials at accelerated speeds.
• Coated and uncoated micrograin substrate carbide and coated cermet specifi cally
engineered for reaming.
Features and Benefi ts
• Lapped ground leads for high-speed cutting.
• Long tool life with increased hole and surface quality.
• High metal removal rates at higher speeds and feeds.
• Decreased runout and improved straightness due to
unequal fl utes.
• Adjustment screw at straight-fl uted HSR reamers to
change internal coolant supply from axial to radial.
• Optimised coolant options for blind holes and blind hole
applications with interrupted cut.
