What are Fine Hard Wire Cutters for Nitinol, Stainless Steel and Tungsten?

Tronex makes many types of hand cutters, mostly for cutting soft copper or similar wire for electronics manufacturing and jewelry making. Tronex offers oval head cutters, taper head cutters, angulated cutters, tip cutters and stand off cutters for these types of applications.

Tronex Fine Hard Wire Cutters are designed especially for cutting exceptionally fine (.003″ – .025″) hard wire.  These specialty cutters are often used under a microscope and cut very fine hard wire including Nitinol, stainless steel, Elgiloy and Tungsten. These cutters are ideal for cutting stents, catheters and braided mesh.

Tronex makes two types of Fine Hard Wire cutters: Class T Fine Hard Wire Cutters and Class W Fine Hard Wire Cutters.

Class T Cutters:

Tronex Class T cutters are made from precision machined cutter blanks where solid tungsten carbide material has been silver brazed in the cutter jaw. Diamond grinding then forms the head shape and sharpens the cutting edges. This tool design, with its dual material construction, combines the high yield strength of carbon steel with the intense localized hardness of tungsten carbide. Cutting edges of CLASS T cutters have a hardness of 79 to 81 HRC. CLASS T cutters can cut thicker and harder hard wire than CLASS W cutters. Also, the handles and jaws of CLASS T cutters are tougher than those of CLASS W cutters.

Tronex Class W cutters are made entirely from solid tungsten alloy steel. This material is machined and formed at the Tronex factory to high dimensional tolerances with exceptionally sharp cutting edges and a solid joint design. The cutters undergo a special furnace-hardening process to achieve a hardness of 66 to 68 HRC on both cutting edges. (Cutters made of carbon steel have maximum edge hardness of 62 to 63 HRC.) CLASS W cutters have smaller tips than CLASS T cutters. This property enables these cutters to cut in more confined areas than CLASS T cutters. CLASS W cutters are lighter than CLASS T cutters. The cutting edges of CLASS W cutters are also less brittle than cutting edges of CLASS T cutters.

Tronex also offers a special heavier duty hard wire cutter which has compound action allowing additional leverage with less pressure and effort on the operator’s part – Tronex Model 7011T. The 7011T can cut hard wire from .012″-.032″ in diameter.
