uxcell 5/16" H8 Precision Hand Reamer - Alloy Tool Steel 6-Flute Straight Shank Milling Cutter (2-Pack) - Perfect for Metalworking, DIY Projects & Precision Drilling

Hand Reamers 9CrSi (Alloy Tool Steel) Tool The 9CrSi steel is a low alloy tool steel and low speed cutting tool steel. It has high hardening capacity and high tempering stability. Good for wide ranges of applications. Straight Flute Straight flute tools allow chips to collect in the flutes when cutting. Well suited for most applications in shallow cuts. For reaming cylindrical shape holes. Easy to Use Can be hand operated by use of wrenches. Great for light cut, repair work, or simply for enlarging holes. Always keep reamers clean, and used with machine oil for long service use. Features Designed with the base substrate without any additional coatings With high hardness and durability, the reamers provide finish cuts. Holes can be with exact size and shape after the reamers' processing. Wide Applications Used for handicraft processing, and bore machining. Suitable for accurate reaming in aluminum, cast iron, copper, plastic, wood, and other soft materials. 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. Tips Reamers are with one or more cutter teeth. 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.
