Key features and what they mean to me
I appreciate how the swivel base reduces the fumbling around when I’m trying to center a pilot or align a cutter on a piece of structural steel. The unit is around 31.9 pounds, so I still consider it portable compared to older mag drills, but expect to use two hands for transport over uneven ground.
Real-world use and limitations
In short, this is my go-to when I need a capable, portable mag drill that won’t slow me down on a mix of shop and field tasks.
Replacement Handle 1/2-20 Thread Hougen
This replacement handle is a practical, no-frills fix when a factory handle is damaged or missing. It’s small and inexpensive yet machined well enough to feel solid during use.
When a handle on a mag drill gets banged up or lost, this 1/2-20 replacement handle is an easy, inexpensive fix I’ve used in the shop. It’s small (4.5" long) and feels robust enough for normal feed control tasks.
Why I keep one around
If your drill’s handle uses the 1/2-20 thread, this part will get you back to work fast and avoid waiting on a longer OEM order. I also like that it’s American-made — that often gives me confidence in fit and finish.
Practical note
Overall, a handy little part to have in a maintenance drawer if you operate Hougen HMD904 units.
Hougen 10731 1/2" Keyed Chuck Adapter
This 1/2" keyed chuck lets you use standard twist drills and jobber bits in your mag drill, which I found useful for pilot holes and tapping work. Fitment can be tricky — confirm threading before purchase.
I like having a 1/2" keyed chuck on hand when I want to switch from annular cutters to conventional twist drills for pilots, taps, or through-holes that don’t need a slug. The 10731 fills that role and is simple to fit when you have the correct spindle adapter.
Practical benefits
That said, one of the common frustrations is thread mismatch — some users have reported it being 5/8-16 instead of the expected size, so I always measure before I commit. When the thread fits, it works fine for lighter drilling tasks.

Practical tip
Overall, it’s a sensible buy if you want better protection and organization for your HMD904 setup.
Final Thoughts
My top pick overall is the HMD904S Fabricator's Kit with Coolant (9.6/10). Why? It’s the most turnkey option I tested — integrated coolant, quality cutters, a chuck and adapter, plus a solid carrying case. If you want to walk into a job and start drilling clean, cool holes immediately, this kit saves time and keeps cutter life longer. Ideal for serious fabricators who tackle varied hole sizes and thick plate and who want fewer trips to the tool crib.
If you need a reliable shop workhorse, choose the HMD904 115V Fabrication Magnetic Drill (9.3/10). It delivered consistent hole quality, fast repeatable setups, and useful safety features like the lift detector. I reach for this one when speed and repeatability matter in production runs or frequent on-site jobs where 115V power is standard.
Quick tip: if you frequently work in tight or awkward positions, the HMD904 Swivel Base is a great secondary pick for its portability and alignment flexibility.
As a fabricator, I can’t overstate how much the 12006 annular cutter kit changed my workflow. Those M2 HSS cutters in 12,000 series are tough and give a clean cut up to 2″ DOF. If you do heavy holes, invest in good cutters — cheaper ones will chew up fast.
Great point, Sophie. Would you recommend a particular maintenance routine (sharpening or regrinding) for extending their life?
Yes — keep them sharp and maintain the weldon shank surface. Use proper speeds/feeds and coolant. When they dull, have them reground by a shop that knows annular cutter geometry — it’s worth it.
Good article, but wanted more on ergonomics. The HMD904S swivel base model looks promising for awkward setups, but I found the handle placement a bit cramped on my last job. If you’re doing repetitive mounting on I-beams, try the swivel base — it really helps align without wrestling the whole unit.
I bought the factory replacement handle (mag replacement handle 1/2-20) — simple and solid. Not a comfort miracle but it’s durable and cheaper than fancy grips.
Thanks, Daniel. Noted — we should include a short ergonomics section in future reviews. Did you swap handles or try any aftermarket crank handles for comfort?
I swapped to a slightly thicker wood grip for long days. Cheap fix, big difference.
I’m torn between the HMD904 115-Volt Magnetic Drill with integrated coolant and the HMD904S swivel base coolant model. Anyone have a clear use-case for choosing one over the other? Also — does the replacement carrying case (09202) fit the swivel base snugly?
If you need more alignment flexibility and work on awkward geometries, choose the swivel base HMD904S. For straightforward shop use where portability isn’t as critical, the regular integrated coolant model is a great value. The 09202 case fits the standard HMD904 well; fit for swivel-base models can be tighter — check Amazon listing photos and measurements before buying.
I have the swivel base and the 09202 case fit, but with minimal extra room for accessories. I ended up carrying extra cutters in a small separate pouch.
I love the sarcastic title, lol. I have a small shop and the HMD904 (115V with integrated coolant) has been my go-to for two years.
Pros: coolant keeps cutters cooler, less smoke, nicer finish.
Cons: it’s not featherweight — if you need to move it solo a lot, consider the swivel-base for easier positioning.
Also pro-tip: label your cutters and keep a slim magnet tray in the case. Cuts down on cussing when a slug disappears into your toolbox. 😂
How thick do you usually cut with yours? I’m thinking of using the 12006 cutter set for some heavier plate.
Haha that ‘cussing’ line 😂 I lost a slug into my bucket once and it played hide and seek for days. Labeling cutters is underrated.
Love the pro-tip, Ava — the magnet tray is such a small addition but a huge time-saver. Appreciate the real-world notes on portability too.
Eddie: I routinely run up to 1″ plate with the 12006 series when I need big holes. Feed slow and use the coolant — they eat through thick steel nicely.
Great roundup — I actually bought the Hougen HMD904S complete kit after reading something similar earlier this year. The integrated coolant and the Rotabroach cutters are worth every penny if you do repetitive work. Case is sturdy too. I will say it’s a bit of an investment upfront but saved me time hunting accessories.
Thanks for sharing, Jenna — glad the kit worked out for you. Did you have to replace any cutters early on or did the included set hold up for a while?
Totally agree. The carrying case made it easy to bring to sites. Saved me from forgetting the adapter once — not fun. 😅
I’ve had the same kit for about 8 months. Cutters still good for most steel I use, but I keep a backup set for cast iron — they dull faster. Also the coolant really extends cutter life.
Nice comparisons. One detail I keep worrying about: the 1/2-20 replacement handle threading and the 1/2″ chuck compatibility — does anyone know if there are slight thread spec differences between HMD904 production runs? I don’t want to order a handle or chuck that won’t thread.
Thanks — I’ll measure and double-check the Amazon Q&A before hitting buy. Saves a headache.
There have been occasional variations between production runs. Best practice is to confirm the exact part numbers on your unit or measure the thread before ordering. Some sellers list compatibility explicitly — check those listings or Hougen’s parts diagrams.
I had to return one chuck once — wrong thread. Seller replaced it quickly. If buying aftermarket, pick sellers with clear fitment guarantees.
Nice write-up. Quick question: anyone tried the 1/2″ chuck (Hougen 10731) on the HMD904S kit? I want to use standard twist drills for pilot holes but worried about fitment or losing precision.
I installed one last month. Took a tiny bit of fiddling to thread it fully but once seated it’s fine for pilot/tap work. Just don’t expect the same accuracy as an annular cutter — use it for prep, not final bore on tight-tolerance parts.
Good question — the review noted that fitment can be tricky. If you order the 10731, double-check the thread spec on your unit (some models vary). When fitted correctly, it’s handy for pilot holes but not as rigid as annular cutters.
Short, sarcastic review from my side: I tried to magnetically attach one of these to my old rocket for giggles — obviously didn’t work. 😂
On a serious note: the integrated coolant models actually do make a difference for finish and cutter life. Anyone tried water-soluble coolant vs oil-based on HSS cutters?
I use a semi-synthetic water-soluble in the shop. Cleaner than oil and still decent cutter life. For stainless I switch to specialty coolants.
Lol about the rocket. Regarding coolant: water-soluble coolants are common for annular cutters on steel — good cooling and wash-off. Oil-based can give better lubricity for some alloys but makes cleanup harder. Choose based on materials you cut and shop cleanliness preferences.
Thanks — I’ll try the semi-synthetic. Less mess sounds like a win.
