Devices and methods for tissue removal are disclosed herein, including those in which a powered rotary tool actuates a cutting blade to sever tissue and drives an auger to transport the severed tissue proximally through the device. The severed tissue can be collected in an on-board collection chamber for subsequent use as graft material or otherwise (e.g., assay, analysis, post-processing, etc.). Devices of the type disclosed herein can reduce or eliminate the need to move the device in and out of the surgical site, reduce user input force, and provide improved ergonomics and increased user focus.
