Model guide availableDEWALT DWE1622K
a corded two-speed option for buyers who need a 2-inch annular capacity without maintaining a battery fleet
- Annular diameter
- 2″ maximum
- Cutting depth
- 2″ maximum
A 2-inch annular cutter rating does not mean this drill accepts a 2-inch twist drill. It also does not turn the two fixed spindle speeds into variable speed. Do not copy specifications from DWE1622K-QS or other regional versions into a US purchase.

Model guide availableHougen HMD904
a general fabrication model whose part-number differences matter almost as much as its headline capacity
- Annular diameter
- 1.5″ maximum
- Cutting depth
- 2″ maximum
The newer permanent-magnet HMD904 is a distinct configuration, not a feature to assign to every HMD904. Likewise, swivel models have different weights and magnetic force figures. A product card should identify the exact configuration instead of combining the most attractive attributes across the range.

Model guide availableHougen HMD130
a purpose-built low-profile option when physical clearance prevents an upright drill from reaching the hole
- Annular diameter
- 1.375″ maximum
- Cutting depth
- 1″ maximum
Cutter compatibility is the main purchasing trap. RotaLoc Plus uses a bayonet-style shank, so an ordinary 3/4-inch Weldon set is not a direct substitute. The 1-inch depth limit also means a compact body does not give the same material range as a full-size 2-inch-depth drill.
