Broaches create splines, keyways, and complex profiles in one pass, while reamers finish holes to tight tolerances. Made from HSS or Cemented Carbide with advanced coatings, these tools deliver high precision for automotive, aerospace, hydraulic, and general machining applications.
Broaches and reamers are precision cutting tools used to produce accurate internal and external profiles or to finish holes to tight tolerances. Broaching is a machining process in which a multi‑tooth tool with progressively increasing cutting height removes material in a single linear pass. It is ideal for keyways, splines, polygons, and complex internal shapes. Reaming is a finishing operation that enlarges pre‑drilled holes to achieve precise diameters, improved roundness, and superior surface finish. Broaches are typically made from high‑speed steel (HSS), powder‑metal HSS-PM, HSS-E-PM, or Cemented Carbide, depending on required hardness and wear resistance, while reamers are produced from HSS, cobalt-alloyed HSS, or solid Cemented Carbide with coatings such as TiN or TiAlN to extend tool life. Tooling includes pull broaches, push broaches, shell‑type broaches, straight‑flute and spiral‑flute reamers, as well as holders and guiding fixtures ensuring alignment. Applications span automotive transmission components, gears, hydraulic fittings, aerospace precision parts, mouldmaking, and general metalworking where high accuracy and geometric repeatability are essential.

Citește mai multThe cost-effectiveness of high speed steels is strongly dependent on their alloy components. Strong fluctuations in the raw materials market and resulting price variations have compelled voestalpine BÖHLER Edelstahl to rethink the basic alloy concepts of the high speed steels in our product portfolio. The result is the patented BÖHLER S730 material, which is an economical alternative to the generally applicable standard sort 1.3243 or M35 (BÖHLER S705). Despite its economic advantage, BÖHLER S730 is fully equivalent to the standard 1.3243 in terms of performance.
