Cheap Router Motor vs. $250 Router in a Table: Runout, Collets and Lift Charts

Yo, let me tell you a story. A guy on the Fine Woodworking forum drops a BORA router motor into a Woodpeckers lift and table. Nice setup. Then he puts a dial indicator on the inside face of the spindle and gets about 0.001 in. of runout. Clean. Then he checks it against a bit shank with the manufacturer's supplied ER collets and gets "more than 10x as much." Roughly 0.01 in. Replacement collets from the maker? Just as bad.

That's the whole cheap-router-versus-good-router argument in one number, and here's the kicker: the motor in that story is a BORA, the class of machine that runs around $286 on Amazon. So before we get anywhere near a $100 bargain motor, we've got to talk about what runout actually means, who's measuring it, and what a lift compatibility chart is going to do to your plan.

The $100 Motor Is a Category, Not a Model

I'm going to be straight with you, because I don't do the thing where I make up a test I didn't run. Nobody in this research confirmed a specific router motor selling at or near $100. So when I say "cheap motor" in this piece, I mean the category: the low-cost fixed-base and trim routers you find in the $100 neighborhood. I'm not naming one. I don't have a verified price on one.

What I do have verified is the next class up. The Bosch 1617EVS is a 12-amp, 2.25 HP fixed-base router, and Amazon listed it at $198.08 from a third-party seller. The BORA PM-6200 is 15 amp, 3.25 HP, with a 10,000–20,000 RPM dial. That's the real shape of the market: the $250+ class is documented, the $100 class is a category I can only describe.

And that matters, because the cheapest path into a router table isn't a motor at all. It's the Bosch 1617EVS sitting in its fixed base, screwed down through holes that are already there.

Runout: Read the Number, Then Read the Argument

Runout gets expressed as TIR — Total Indicator Reading, the difference between the highest and lowest dial readings over one revolution. The tooling supplier Eversource CNC makes a point worth taping to your fence: a runout spec means nothing unless it states whether it's the collet alone, the holder alone, or the whole assembled system, and at what distance from the collet face it was measured. Two "0.001 in." claims can be describing two completely different things.

That's exactly why the Fine Woodworking thread is worth reading in full instead of grabbing the headline. The 0.001-versus-0.01 number is one user, on one motor, with his own setup. A respondent in that same thread pushed back hard: 0.01 in. is unlikely to cause visible surface problems, and the poster's indicator setup wasn't consistent — the indicator angle differed between tests, and one measurement may have been taken against a bearing rather than a shank. Another voice suggested the collet nut, not just the collet, could be the real culprit, and recommended checking drill rod of known diameter instead of a router bit.

I'm not going to tell you which side wins that argument, because there's no lab result. What I will tell you is this: if you're chasing runout, the collet is a real cost lever, and it cuts both ways. Replacement ER collets run from about $5 for cheap imports to nearly $100 from McMaster-Carr, per that same thread. A bargain motor with a sloppy collet can sometimes be fixed with a decent one. Sometimes the nut is the problem. Sometimes the spindle is. Don't generalize from one guy's dial indicator.

Speed Control: The Feature You Can't See on the Box

Mid-priced machines advertise speed holding. The Bosch 1617EVS runs 8,000–25,000 RPM no-load variable, and Bosch's product page says its Constant Response circuitry "will maintain a constant speed throughout the cut." The BORA PM-6200 gives you a 10,000–20,000 RPM dial with soft start, per Popular Mechanics. Those are named features on named machines.

Now here's what I can't give you: a verified RPM droop measurement on a cheap motor under load. I don't have one, and I'm not going to pretend a test I didn't see happened. What I can say is that "maintains constant speed under load" is the kind of feature that shows up on the spec sheet of a $200–$286 router and tends to go unmentioned on the bargain end. Whether your specific bargain motor sags is something only your ear and your feed rate will tell you.

The Lift Chart Is Where the Cheap Plan Dies

Here's the part that actually costs you money. A router lift is not a universal motor holder. Timber & Tools' buying guide says it plainly: a lift clamps a compatible removable motor, and you need to record your motor's diameter and base type and check the lift maker's current chart, including any adapter or reducing collar.

The Kreg PRS5000 runs on numbered clamp-block hole patterns keyed to router families. Bosch 1617EVS is pattern 5, the 3.5-in. motor group alongside DeWalt DW618 and Porter-Cable 690/890. Porter-Cable 7518 is pattern 1. The guide lists Milwaukee 5625 and Triton TRA001 as unverified for that lift — and specifically warns you not to assume the 5625 fits because the 5626 shows up in Kreg's chart.

So walk the cheap route with me. You buy a bargain motor. You go to the lift chart. Your motor isn't on it. Now what? You buy a different motor — the ~$286 BORA, or the ~$198 Bosch — or you buy a different lift, and I don't have a verified lift price to quote you anyway. Either way, the "$100" plan just grew a second purchase.

Meanwhile, the Bosch 1617EVS skips the lift entirely. Its RA1161 fixed base has threaded holes in a common 3-hole pattern for router-table mounting and gives you above-table bit-height adjustment, per Bosch. Fine Woodworking forum users confirm running it that way, and one notes it mates with a JessEm Rout-R-Lift II as a reasonably priced combo. Above-table bit changes are a lift-or-base feature, not a motor feature. A bare motor with neither leaves you reaching under the table every time you want to touch the bit.

And if you're wondering about the old gold standard, the Porter-Cable 7518: multiple forum users reported it discontinued and unavailable new in 2020–2021. The Triton 3-1/4 HP motor was built to the same 4.2 in. diameter, per Infinity Tools, so it drops into the lifts the 7518 used to fill. Don't plan a build around buying a new 7518.

What the Cheap Motor Genuinely Can't Do

I want to be fair here, because bargain motors have real uses. But in a table, three things are documented gaps.

No documented lift compatibility. Unless your motor appears on a specific lift manufacturer's chart, above-table bit changes and fine height adjustment aren't assured.

Lower power ceiling. The verified mid and upper class runs 12 to 15 amp, 2.25 to 3.25 HP. A trim router in the cheap class is typically 1 to 1-1/4 HP — the Makita RT0701C is 1-1/4 HP, verified. That's the class least suited to large raised-panel or heavy template bits in a table. I'm not going to claim it fails; I have no cut test. I'm telling you the horsepower difference is real and it's not in your favor.

No above-table adjustment without a lift or a base that has it.

Put a Cost on It

Here's the math I'd actually run before buying anything. The Bosch 1617EVS at $198.08 gives you a table-mountable base with above-table height adjustment out of the box. The BORA PM-6200 at ~$286 gives you 3.25 HP and a dial, but it needs a lift you haven't priced yet. A bargain motor gives you a lower price tag and a question mark on the chart, plus collets that might run you $5 or $100 to chase down if the runout bugs you.

The difference isn't $100 versus $250. It's whether your motor's name is on a compatibility chart and whether your base can raise the bit from above the table. Go check the chart for whatever motor you're eyeing before you spend a dollar. If it's not on there and your base can't do above-table adjustment, you already know what you're buying: a motor that lives under the table and a hand that lives under it too.
