Overview
A corded electric drill, model DKPHRHG150C1-K1UL-GYAZ, running on 120 volts and drawing 12.5 amps. It turns at 1000 RPM and measures about 11.2 by 7.87 by 16 inches, sized like a larger format drill rather than a compact driver.
The 1-1/4 figure in the title likely points to a drive or chuck size rather than a brand name, since no real brand is given in this listing. A 12.5 amp draw on corded 120V power and a relatively low 1000 RPM top speed both point toward a heavy duty drill built for torque over speed, closer to what tradespeople use for large diameter holes than a general handyman drill.
- Corded electric, 120 volts
- 12.5 amp motor
- 1000 RPM
- 11.2 x 7.87 x 16 inches
Who it's for
Suits users needing a corded, high torque drill for large bore holes in wood or metal, where low RPM and high amperage matter more than speed. Not a fit for light home projects or anyone wanting a cordless, lightweight driver.
Pros and cons
- High 12.5 amp motor for demanding drilling
- Corded for continuous power without battery limits
- Low 1000 RPM top speed limits use for fast drilling
- Bulkier size than a standard handheld drill
- No clear brand listed
Performance notes
At 12.5 amps on a 120V circuit, this pulls more current than typical light duty drills, and the 1000 RPM top speed is low enough to favor torque over spindle speed, a combination usually built for drilling large holes or driving heavy fasteners rather than quick everyday tasks. Its 11.2 by 7.87 by 16 inch size is bulkier than a standard handheld drill, consistent with a heavy duty corded design.
