6pcs Chucking Reamer Set H7 Lathe Machine Reamer Straight Flute 4mm-12mm

Information Reamers are with one or more cutter teeth. Holes can be with exact size and shape after the reamers' processing. Finished product can be smooth, intact and more beautiful. Reamers can be used to process holes in small cuts based on guiding function, such as: holes with diameter tolerance in ≤IT8; holes with requirements in surface roughness (≤Rz12 generally); holes with requirements in roundness tolerance; holes with requirements in cylindricity; stepped holes (different diameter holes on the same axis); series holes (diameter holes on the same axis) with requirements in high coaxality. No Coatings Designed with the base substrate without any additional coatings, good for wide ranges of applications. Features Used for light cut, repair work, removing stock or simply for enlarging holes. Chucking reamers (machine reamers) are used on lathes, drill presses and screw machines. Round shank can be used with a wide variety of tool holding systems. Wide Applications Cut and remove the thin layer metal on hole surface that has been processed, mainly to improve the precision of holes and reduce the surface roughness. Used for semi-finish machining and finish machining of holes. Chucking Reamer: Size: 4mm, 5mm, 6mm, 8mm, 10mm, 12mm; tolerance: H7. Features just the base substrate without any additional coatings, good for wide ranges of applications Material: High-speed steel tools are with combination of hardness and toughness for wear resistance, suitable for general purpose applications Applications: Cut and remove the thin layer metal on hole surface that has been processed, mainly to improve the precision of holes and reduce the surface roughness Features: Straight flute tools allow chips to collect in the flutes and can make shallow cuts in most applications
