Stainless Steel Alloy Shrink-Fit System



"The MST SLIMLINE is a compact shrink-fit system for cutting tools that features a special stainless steel alloy with a coefficient thermal expansion that is 60% greater than H13, a common shrink-fit material," said a company spokesperson.

"The MST SLIMLINE shrink-fit system requires less than 400 °C (750 °F) to execute the shrink-fit process, a temperature range that will not affect the physical properties of the material. In contrast, the commonly used H13 material requires approximately 700 °C (1,300 °F), a heat range that may affect H13's physical properties. Excessive temperature becomes even more critical for smaller carbide tools, especially those with diameters smaller than 1/4"."

The strength of SLIMLINE'S material makes possible a wall thickness of .059" with 3° taper angle for interference-free cutting. The slender MST SLIMLINE enables machining in tight spaces. The low-interference SLIMLINE system combines high-speed capability with accuracy of .00012" TIR at 4x diameter for most models. And SLIMLINE requires only inexpensive heating devices with industrial hot air guns for the shrink-fit process.

The MST SLIMLINE shrink-fit system is available in two-piece models and integral models including a curve design for 5-axis applications. SLIMLINE is also available in regular and slim designs in various lengths and shank types.
