Spline or Rotary Drive Tools
Explore our collection of heavy-duty chisels, drills and coring bits designed for select top-hammer models from brands like Bosch, DeWalt, Hitachi, Metabo, Milwaukee and more. In this category, “spline/rotary drive” refers to a special shank style that allows your hammer’s drive teeth to spin freely while the tool itself remains fixed — no ridged splines to rotate the chisel. 
Whether you’re tackling demolition, chiseling thick concrete, or working through reinforced slabs, the tools in this category deliver rugged, construction-grade performance.
Need help confirming if the shank style fits your hammer? Use our “Chisel Lookup by Hammer” tool at the top of the page — or call us at 800-239-1434 for guidance.
