TMC 75 Series Lightweight Breadboard

See a larger image


Another in a long line of TMC innovations, our 75 Series Breadboards minimize both weight and cost. A patented manufacturing technique allows us to form countersunk, tapped holes in a thin top skin of stainless steel. The holes are not drilled or punched, but fabricated in a way that effectively “thickens” the skin in a small ring around the threads. No inserts are used and the tapped holes are 3 threads deep.

These tops have relatively high levels of rigidity, as they utilize our standard steel core. However, with their thin top and bottom skins, they cannot have the rigidity and damping properties of our 78 and 77 CleanTop® II Breadboards. They are ideal when light loads are anticipated and low weight and/or cost are the most crucial factors.

The weight savings - 50% less than our 78 Series Breadboard - is derived only from the lighter gauge skins.

This lightweight design is available from stock in the sizes listed below. A full range of sizes and materials is available on a custom basis. Contact TMC for pricing and delivery for custom configurations.
