  • The HMT ImpactaMag HSS reamer is a unique double-use reamer for enlarging and aligning holes in metals and hard materials; with a specially designed cutting geometry that is designed to allow the tool to be used in an Impact wrench or a Magnet drill.
  • When used in an Impact wrench it is secured into a special adapter meaning the tool is easier to control, apply correct feed rate, and withdraw from the finished hole, enhancing tool life.
  • This reamer will also fit into a standard weldon magnet drill arbor, providing a versatile 2 in 1 solution for circumstances where it may be more appropriate to use a magnet drill.
  • Ideal for steel erectors and bridge work. Used for Network Rail bridge refurbishment and strengthening.
  • Ideal for modifying and enlarging holes ready for the installation of TCB bolts and friction grip bolts.

ImpactaMag reamers are now available in intermediate sizes.

UNIQUE 6 flute design for faster, smoother cut.

For 1/2in Drive Impact Wrench use 00200-12A-19 HMT ImpactaMag Adapter. For 3/4in Drive Impact Wrench use 00200-34A-19 HMT ImpactaMag Adapter.

Impact wrench driven reamers are not recommended for use with laser or plasma cut holes. Heat affected holes can be enlarged using the ImpactaMag reamer with a slow speed magnet drill.
