Hougen HMD904 Guide: Capacity, Fit and Buying Checks
Hougen HMD904 is a general fabrication model whose part-number differences matter almost as much as its headline capacity. This is a specification-based buying guide, not a hands-on test. Use the exact model number and the required hole dimensions to decide whether it belongs on your shortlist.

What the documented specification tells you
Depends on part number. A model-specific minimum mounting thickness has not been confirmed here; check the exact operator manual before choosing a workpiece.
- Power: 115V US variants; separate 230V variant
- Annular diameter: 1.5 inches maximum
- Cutting depth: 2 inches maximum
- Speed: 450
- Cutter interface: 3/4-inch; Hougen 12,000-Series and Copperhead cutters
- Base: Electromagnetic standard variants; distinct permanent-magnet 0904122
When it belongs on your shortlist
Make a package matrix before comparing prices. Hougen lists 0904101 as a basic 115V model, 0904102 with coolant bottle, 0904103 with swivel base, and 0904104 with both. Fabricator kits add another layer. A lower-priced basic drill is not necessarily a better value than a package containing accessories you already planned to buy.
Suppose two offers both say HMD904 and one includes a swivel base. The extra adjustment may be valuable when repeatedly locating holes, but it should be compared as a separate feature with its own weight and price. If you already own compatible cutters, a large cutter bundle might add little value. The most economical package is the one that fills actual equipment gaps.
Inspect the exact Amazon offer
Check model, regional version, included accessories and current seller details before ordering.
Check AmazonThe limitation to check first
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. Confirm the exact part number so you do not combine a swivel model’s features with a standard model’s specifications.
Questions, answered
Does every HMD904 include a coolant bottle?
No. Hougen's part-number table distinguishes versions with and without a coolant bottle. Match the manufacturer's configuration to the exact offer.
