Tough performer

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. Bahco claims 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.

A summary of the improvements made include:

Raw Material: a new, higher grade of HSS special design wire is now being used, improving both the hardness and toughness of the blade.

Geometry: the changes on geometry have only affected the variable tooth, giving a distinctive new look to the 3851PRX family, clearly differentiating it from the rest of Bahco’s bandsaw blade range. The more traditional constant tooth (H and HA & R) version remains unchanged.

Production process: 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.

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

Product features and benefits: the improved blade is now available in sizes from 6mm to 80mm. It 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.

Applications: Contour cutting, including aluminium and stainless steel, along with production cutting and general-purpose applications, cutting solids, bundles, profiles and castings.
