Utoolmart 3mm H8 Alloy Steel Hand Reamer - 6 Straight Flute Precision Milling Cutter Tool (1pc) - Perfect for Metalworking, DIY Projects & Jewelry Making

Utoolmart Chucking Reamer Lathe Machine Reamer Round Shank Milling Cutting Tool for Metal Non-Ferrous Metal Copper High-speed steel tool is good for general purpose applications, with combination of hardness and toughness for wear resistanceFeatures just the base substrate without any additional treatment or coatings, suitable for wide ranges of applicationsCan be used with a wide variety of tool holding systems. Reamers are used for light cut, repair work, removing stock or simply for enlarging holesAllows chips to collect in the flutes when cutting, well suited for most applications in shallow cuts Designed for accurate reaming in most materials, using all types of equipment including screw machines, turret lathes, drill presses and machining centers The Reamer is made of high-speed steel, high temperature, wear resistance, good toughness, etc.Used for semi-finish machining and finish machining of holes. Suitable for stainless steel, carbon steel, cast iron, die steel, alloy steel, tool steel, non-ferrous materials.Can be used on processing holes, mainly to improve machining precision of holes and reduce the roughness. Can be manually operated or installed on drilling machines to work. Feature The Reamer is 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. Technical Parameters Precision: H7 Material: HSS(high-speed steel) Surface treatment: Uncoated Package Content Chucking Reamer Tips: 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 genrally); 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.
