Hand Reamer Workhorse For Metalworking Seven Sixteenths Inch Alloy Tool Steel 9CrSi H8 With Six Flutes High Precision Reamer Square Shank 72mm Flute Length 130mm Overall Length Milling Cutter Tool
This hand reamer is a high-precision tool designed for metalworking and fabrication, ideal for enlarging and finishing holes in aluminum, cast iron, copper, magnesium alloys, and plastics. Made from 9CrSi alloy tool steel and hardened to H8-level drilling accuracy, it helps reduce surface roughness on workpieces. The chamfered angle at the bottom provides orienting effects to maintain axis position and roundness.
✅ 9CrSi alloy tool steel construction for durability and H8 precision
✅ Six-flute design for smooth cutting and better hole finish
✅ Chamfered bottom angle helps orient and maintain axis alignment
✅ Hand-operated with wrenches for light cuts, repair work, or enlarging holes
✅ Suitable for reaming aluminum, cast iron, copper, magnesium alloy, and plastic
