The two corded clippers that built this category. They take the same blades and they are not the same machine: one runs 4,400 strokes a minute, the other 2,700.
Buy the Andis AGC Super 2-Speed for a doodle, poodle or any dense curly coat: 4,400 SPM cuts cleanly where 2,700 chews, and the vent-free housing cannot clog with undercoat. Buy the Oster Golden A5 for long thick coat, heavy weekly use, or if you want a clipper you can have serviced in five years. Both take the same A5 blades.
This page is for you if
You have decided on a corded, detachable-blade clipper and you are choosing between the two oldest names in the category.
You are on the wrong page if
You want cordless, or you are not sure a clipper is the right tool at all. Start at the main clipper roundup, or at Andis vs Wahl if the Oster is not really in your shortlist.
What they have in common
Both are corded rotary-motor clippers built around the detachable A5 blade standard— the standard Oster created and Andis and Wahl adopted. That is the most reassuring fact in this comparison: every A5 blade and guide comb fits both bodies, so your blade collection is not locked to a brand and a clipper upgrade later does not strand it. If you already own A5 blades, either of these will take them.
Both are also genuine working clippers rather than trimmers, with the torque to keep moving through coat that would stall a cheap unit, and both are heavier and louder than any cordless option. And both ship with a single short blade, typically a #10 at 1/16 inch, which is a sanitary-area length and not a body length. Budget for a #4F or #5F with either one — see the blade size chart.

Speed figures are the manufacturers' published numbers, cited in the sources below. Weight and cord figures are published for the Andis; where Oster does not publish an equivalent we have left the row qualitative rather than estimating it.
Blade speed is the difference that shows on the dog
4,400 against 2,700 strokes per minute is not a spec-sheet detail. Blade speed decides how many times each cutting tooth passes the comb tooth while the hair is between them, and on a dense curly coat that determines whether the hair is cut or pushed. Clipping a Bernedoodle with a slower clipper is where the tracking lines and the chewed, uneven finish come from, and no amount of technique fully compensates.
The flip side is heat. Faster blades get hotter, which is why the Andis design removes the fan intake entirely and why the Oster uses filters you can pull out and clean. Neither approach removes your obligation to oil the blade and check its temperature against the back of your hand every few minutes; both approaches work if you do.
On a long, thick, knot-prone coat — a Great Pyrenees jacket, a heavily coated farm dog — the slower Oster is not at a disadvantage. There the job is shifting bulk, torque matters more than blade speed, and the A5 has the reputation it does for good reason.
The same A5 blade fits both clippers. What differs is how many times a minute it passes the comb teeth.
Noise, and why it decides more than you think
The Oster is the louder and buzzier of the two, and it is the louder of almost anything in this category. That matters because a dog that will not stand still gets a worse haircut than a dog that will, whatever is in your hand. If your dog is noise-reactive, the Andis is the better of these two and a cordless lithium clipper is better still — see cordless clippers, accepting that a 5-in-1 adjustable blade has less bite than a dedicated one.
Serviceability, which is a real argument
The Golden A5 has been in production for decades, so parts, brushes, armatures and service exist in a way they do not for most modern tools. If you groom several dogs a week and you would rather rebuild a clipper than replace it, that is a genuine reason to choose it — and the used market is deep, which also means a second-hand A5 is the cheapest real route into a detachable-blade clipper.
The counterpoint: for a one-dog household, you will not wear either machine out, so serviceability buys you nothing and blade speed buys you a better finish every eight weeks.
Neither one shaves a double coat
Both of these have the power to take a Husky, Samoyed or Shepherd down to the skin, and doing it damages the coat — the guard hairs may come back thin, pale or not at all. A clipper on a double coat is for trousers, sanitary areas and feet. Read why not to shave a double coat before you put a blade on one.
Before the clipper comes out
Whichever you buy, the clip is only as good as the brush-out before it. A blade will not pass through a tangle; it stops, pulls and leaves a line. Get the coat combed through to the skin first — the right tool for that is in the dog grooming brush roundup — and if the coat is already felted, clip underneath the mat rather than fighting through it.

Every pick, in order
01
Dense, curly and doodle coats
Andis UltraEdge AGC Super 2-Speed
3,400 and 4,400 SPM with a vent-free housing that fine undercoat cannot pack into. The faster, cooler machine.
Andis publishes 3,400 and 4,400 strokes per minute, which is roughly 60 percent more blade speed than the Oster at the top end, and blade speed is what gives a clean cut on dense curly coat rather than a chewed one. The vent-free housing is the other half of the case: there is no fan intake for doodle undercoat to clog, which is the failure mode that kills clippers on this coat type. It is the one we recommend by default for anything curly.
Blade speed9.5
Heat management9.0
Torque through felt8.5
Noise and vibration6.5
Serviceability7.5
Overall8.6 / 10
What it gets right
+Two usable speeds rather than one compromise speed — 3,400 SPM for bulk removal, 4,400 for finish work
+Takes the whole A5 detachable blade range, so one clipper covers every coat length you will ever need
+The vent-free housing is the reason it survives doodle coats: there is no fan intake for undercoat to pack into
+14 ft cord means you are not fighting an extension lead around a grooming table
What it gets wrong
−Corded, so you work around a cable with a dog that may not stand still
−Ships with one blade; a doodle or double coat needs at least two more, which is a real added cost
−Heavier in the hand than a cordless unit over a long session
Who should skip itSkip it if you own one short-coated small dog — this is more clipper than that coat will ever need.
The A5 blade standard is named after this clipper, and it has been in production long enough that parts, blades and service are everywhere. Oster publishes 2,100 and 2,700 SPM from a 45 watt motor with removable, cleanable air filters, which is a different design philosophy from the Andis: it is cooled by moving air through the body rather than by having no intake at all. Slower at the blade, strong on long knot-prone coat, and the one of the two that a worn unit can be rebuilt rather than replaced.

Serviceability9.5
Overall7.6 / 10
What it gets right
+The original A5 clipper — blade availability is effectively unlimited and cheap second-hand
+Torque where it matters: long coats prone to matted knots are what it was built for
+Serviceable. Parts exist, and a worn unit can be repaired rather than binned
What it gets wrong
−Loud and it vibrates more than a modern brushless clipper
−Runs warmer than the newer vent-free housings, so blade temperature needs watching
−Heavier than anything cordless
Who should skip itSkip it if your dog is noise-reactive — this is the loudest clipper in this set.
Yes. The detachable A5 mount is a shared standard, so Andis UltraEdge, CeramicEdge and Oster Cryogen-X blades all fit both bodies, as do A5 guide combs. The one exception is a proprietary 5-in-1 adjustable blade, which fits neither.
+−Is the Oster A5 or the Andis AGC faster?
The Andis, substantially. Published figures are 3,400 / 4,400 SPM for the AGC Super 2-Speed against 2,100 / 2,700 SPM for the Golden A5 2-Speed. On dense curly coat that gap is visible in the finish.
+−Which one is better for a doodle?
The Andis AGC Super 2-Speed, for two reasons: the higher blade speed cuts curl cleanly, and the vent-free housing has no fan intake for fine doodle undercoat to pack into. Full picks on best clippers for doodles.
+−Is the Oster Golden A5 still worth buying?
For long thick coats, high-volume use or a repairable tool, yes. It is the clipper the blade standard is named after and it is still in production. For a single curly-coated dog, the Andis is the better buy.
+−Do either of them come with a useful blade?
Not for a body clip. Both typically ship with a #10 at 1/16 inch, which is a sanitary length. Buy a #4F or #5F at the same time; the blade size chart explains which length gives which finish.
+−Which is quieter?
The Andis, clearly. The Golden A5 is the loudest clipper we cover, with more vibration through the body. On a sound-sensitive dog that is the deciding factor, not the blade speed.
How this page was put together
We define the coat problem the tool has to solve, shortlist products currently sold, compare the manufacturers’ documented specifications against what that coat actually needs, and cross-check against published findings from named sources. We do not test these tools on our own dogs under controlled conditions, and we will not say we do. Where a figure comes from a manufacturer, we name them; where it comes from someone else’s testing, we cite them. We print no prices — a stale number is worse than none. Read the full method.
