Tackling tough materials with longer blade life

This upgrade now offers a wider operating envelope within each TPI, coupled with more precise tooth form, making the new, 3851PRX ideal for cutting the toughest materials.

It is a more universal blade which will cut a greater range of workpiece sizes and shapes than conventional blades.

“This represents a massive evolution of the 3851, with improvement in three key areas: raw material, geometry and production process,” says Peter Storr, Bahco’s bandsaw specialist in the UK.

The improvements include: a new, higher grade of HSS Special design wire is now being used, improving both the hardness and toughness of the blade; changes to the geometry giving a distinctive new look to the 3851PRX family and clearly differentiating it from the rest of Bahco’s bandsaw assortment. The more traditional constant tooth (H, HA, R) versions remain unchanged.

Furthermore, the new 3851PRX is manufactured on machinery specially developed for the upgrade, giving a better, consistent finish to the material. It also generates less friction and vibration, consequently improving fatigue failure.

During development the upgrade has been strongly supported by R&D testing and field trials, using prototype, standard and main competitor blades. These field trials were designed to replicate real life applications while scientific tests evaluated how the blades perform when used in extreme conditions. In both test types the new 3851PRX outperformed the old 3851 and its main competitors.

Other benefits mean the improved blade is now available as a complete selection from 6mm to 80mm. This offers cutting solutions in both production cutting and general purpose applications. Improved chipping resistance is achieved without compromising hardness, with less vibration and greater resistance to heat and wear giving longer blade life.

When it comes to applications, the new blades can be used for contour cutting, including aluminium and stainless steel, along with production cutting and general purpose applications, cutting solids, bundles, even profiles and castings.
