Tronex® Cutters Overview
Tronex® Fine Hard Wire Cutters
Tronex® Hard Wire Cutters are designed specifically for cutting very
fine hard wire typically used in medical device manufacturing.
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 used in medical device manufacturing.
There are two classes of Tronex® Hard Wire Cutters: Class W Cutters and Class T Cutters. See the table below for comparison:

Class W, Tronex® Fine Hard Wire Cutters
Tronex® Class W Fine Hard Wire Cutters are made entirely from a solid alloy of tungsten, cobalt, chromium and vanadium to
have cutting edges that are very sharp and very hard. The cutting edges are hardened by a special
heat-treating process to a hardness exceeding 67 on the Rockwell C scale. The hardness of the edges
extends to a significant case depth. The razor-sharp edges cut hard wire in stainless steel, nickel,
Nitinol (nickel and titanium), maximum diameter for tungsten wire is 0.025mm (0.001").
Precision cutting of very fine wire is achieved through an especially fine joint design. The joint
incorporates a hardened screw/nut combination,
matched bearing rings and a Delrin® washer. Ends are cut flush, smooth and free of burrs.
Tronex® Cutters
feature stainless steel springs, cushion grips and an anti-dulling protection device.

Class T, Tronex® Fine Hard Wire Cutters
Tronex® Class T Cutters are made from precision machined cutter blanks in which 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 hard wire than Class W Cutters.
Handles and jaws of Class T Cutters are tougher than those of Class W.
