Maykestag HSS-E NC Machine Reamer 9.9mm Left-Hand Spiral

At a Glance: Precision 9.9mm H7 NC machine reamer manufactured from HSS-E with left-hand spiral flutes and a precision 10mm h6 cylindrical shank.

The Maykestag Code 3080 9.9mm NC machine reamer is designed for precision sizing and finishing of pre-machined holes. Manufactured from HSS-E high speed steel and produced in a Form D, left-hand spiral configuration similar to DIN 212, it provides the controlled cutting geometry required for accurate machine reaming. The 9.9mm reaming diameter is manufactured to H7 tolerance, while the 10mm cylindrical shank uses an h6 tolerance for accurate tool holding.

Precision finishing for accurately sized holes

A reamer removes only a small amount of material from an existing hole, bringing it to its final diameter while improving dimensional accuracy and surface finish.

Product highlights

  • H7 reaming diameter: 9.9mm precision diameter for accurate hole finishing.
  • HSS-E construction: Cobalt-alloyed high speed steel offers excellent wear resistance and cutting performance.
  • Left-hand spiral: Spiral flute geometry designed for controlled machine reaming.
  • Precision shank: 10mm cylindrical shank manufactured to h6 tolerance.
  • Form D geometry: Maykestag NC machine reamer design similar to DIN 212.

Extra Information

  • A machine reamer is a finishing tool and should be used on an accurately positioned, correctly sized pre-machined hole.
  • The catalogue specifies a 9.9mm finished reaming diameter with H7 tolerance.
  • The 10mm shank diameter is manufactured to h6 tolerance.
  • Maykestag lists this Code 3080 range as similar to DIN 212.
  • No suitability rating is specified by Maykestag for steels above 45 HRC or plastics.

Pro Tips

  • Do not use a reamer to create the original hole. Drill, bore or otherwise pre-machine the hole first, leaving only the appropriate amount of material for final reaming.
  • Use the correct cutting speed, feed and lubricant for the workpiece material. Maykestag cutting-condition recommendations can be referenced in the MaySpeedGuide.
  • Accurate alignment between the reamer and the existing hole is important for achieving the intended H7 result and preventing premature tool wear.
  • Avoid stopping or reversing the reamer while its cutting edges are engaged in the workpiece unless specifically permitted by the machining process.
