Overview
The Bosch 1191VSRK is a corded electric drill running on 120 volts and 7 amps, with a top speed of 480 RPM and a weight of 4.1 pounds.
480 RPM is slow for a general purpose drill, which points to a tool geared for high torque, low speed drilling rather than quick hole boring in wood. The 7 amp motor backs that up. The listing doesn't specify chuck size or masonry bit compatibility, so confirm that before buying if it matters to your job.
- 120V, 7 amp corded motor
- 480 RPM top speed
- 4.1 lb weight
- 11 x 11 x 9 inch dimensions
Who it's for
Fits users needing a corded drill built for high torque, slower speed work such as large diameter holes or mixing paddles. Not the right choice if you want fast bit speed for everyday wood drilling or driving screws.
Pros and cons
- 7 amp motor delivers strong torque at low speed
- 4.1 lb weight keeps it manageable for a corded tool of this power
- 480 RPM top speed is slow for general wood drilling
- Chuck size and bit compatibility aren't listed
Performance notes
With only 480 RPM at 7 amps, this drill trades speed for torque, meaning it turns slower but resists stalling under heavy resistance, the kind of setup suited to large bits or dense material rather than quick general drilling.
