Dumont Pattern No. 4 Tweezers are Swiss-made precision instruments ideally suited for handling microscopic parts. The shanks are indented with beveled edges, and the points have been extra honed to a needle-like shape and sharpness. Overall length is 4-1/2" (114 mm) with tips measuring 0.13 mm wide by 0.08 mm thick.

Available in three quality grades — High Precision (HP), Electronic Quality (EQ), and Titanium Swiss (TS) — and across multiple alloys, these tweezers serve the needs of watchmakers, jewelers, and precision assembly professionals at every level.

The High Precision (HP) grade features extensive hand finishing and is considered Dumont's finest quality. These are the tweezers used by the world's most skilled watchmakers. Electronic Quality (EQ) tweezers receive less hand finishing than HP and are optimized for assembly work, making them an excellent choice for everyday professional use. Titanium Swiss (TS) tweezers offer excellent strength with very light weight and are resistant to high temperatures, magnetism, corrosion, and acids.

Features

  • Swiss made to exacting precision standards
  • Extra-honed needle-like points for handling microscopic parts
  • Indented shanks with beveled edges for secure grip and control
  • Available in HP, EQ, and TS quality grades
  • Multiple alloy choices including stainless steel (Inox), anti-magnetic stainless (Dumoxel), Dumostar super-hard alloy, and titanium
  • Dumostar alloy hardened to a minimum Rockwell 61 for near-indefinite point retention
  • Dumoxel alloy is non-magnetic, corrosion resistant, and acid resistant
  • Titanium variant is anti-magnetic, corrosion resistant, acid resistant, and high-temperature resistant
