Sumitomo Electric Hard Metal Carbide solid reamer + SumiReamer + SSR type (for H7 tolerance / blind hole)

Achieves high-efficiency machining with a feed rate of f = 1.6 mm / rev with a balanced design that combines sharpness and cutting edge strength!
Achieves high efficiency and high precision hole drilling with excellent cutting edge quality and weak right-handed twisted flute.
Stable and long-life processing is possible with the reamer exclusive coating.
High-precision hole drilling: Achieves good hole surface quality with excellent cutting edge quality without minute chipping.
Stable and long-life Reamer coating: High-grade, high-hardness, high-strength film with excellent wear resistance and heat resistance.
Stable hole diameter: Stable hole diameter due to reduced rubbing resistance by optimizing the back taper and finishing by cutting.
Smooth chip evacuation: A balanced design that combines sharpness and cutting edge strength with a slightly right-handed twisted flute.
High-speed finishing of pilot holes in carbon / alloy steel (~ 0.28%), carbon / heat-treated steel (0.29% ~), heat-treated steel, high-hardness steel (~ 45HRC), cast iron, and ductile cast iron.
