Andis T-Outliner review
The default outlining tool on most barber stations, and one of the few grooming products that publishes both figures that decide it.

The short version
Buy it if you cut your own lines and want a tool that publishes its figures. A magnetic motor at a published 7,200 SPM behind a published carbon-steel T-blade, 14.5 oz, with a published 2-year warranty. Corded is not a compromise for this job - a lineup is stationary work in front of a mirror. The obligation is maintenance: carbon steel rusts if you leave it wet.

It publishes the two figures that matter
This is rarer than it should be. Across the whole of men's grooming, motor claims are adjectives - "powerful", "high-torque" - and blade material is frequently just "stainless steel" or nothing at all.
Andis publishes 7,200 SPM and carbon steel. Both are checkable, both are comparable against something, and together they describe the tool completely: how fast it cuts and what it cuts with.
Carbon steel, and the obligation attached
Carbon steel takes a finer edge than stainless and holds it longer. On a tool whose entire job is cutting a crisp line, that is the correct material choice and it is why professionals use it.
It also rusts. Hair carries moisture and product residue, and a T-blade left damp in a drawer will corrode - and a corroded blade pulls, which on a hairline is exactly what you are trying to avoid.
Brush it out and oil the blade after every use. This is not optional maintenance, and it is the single thing most likely to determine whether this tool is still cutting cleanly in five years. The routine is thirty seconds.
Corded, and why it does not matter here
A cord looks like a compromise on a spec sheet and mostly is not for this particular job. A lineup is stationary work: you stand at a mirror, you make small precise movements, and you are done in two minutes.
What a cord buys you is no battery - nothing to fade halfway through a line, nothing to degrade over years, nothing to eventually make the tool useless. On a device otherwise built to last decades that is a reasonable trade.
The exception is your own nape. Working behind your own head with two mirrors is awkward enough without managing a cable, and that guide is honest about the difficulty - which is why the cordless version at 7.8 oz is the better pick for self-cutting.
One gap worth noting: Andis does not publish the cord length, which is an odd omission on a corded tool.
Who should buy it
- Anyone cutting lines - hairline, temples, beard edges. The default tool for the job, and it publishes why.
- Anyone who already owns a clipper. This is the second tool that does what the first cannot; the clipper roundup covers the first.
- Anyone cutting other people's hair. Corded, metal, two-year warranty.
- Anyone who will actually oil a blade. Carbon steel rewards it.
Who should not
- Anyone buying a first hair tool. This cuts lines, not hair. Buy a clipper first.
- Anyone doing their own nape regularly. Take the cordless version.
- Anyone who will leave it wet. Carbon steel is unforgiving.
- Anyone who wants guards in the box. There are none at this item number.
The verdict
A single-purpose professional tool that does one job properly and publishes both figures that decide it - which on this site counts for a great deal, because almost nothing else in the category does.
Buy it as a second tool alongside a clipper, oil it after every use, and learn the line before you think about zero-gapping it.

Our pickThe line every barber cuts
Andis T-Outliner T-Blade Trimmer (04780)
A magnetic motor published at 7,200 SPM behind a carbon-steel T-blade, corded, 14.5 oz, with a published 2-year warranty. It is the default outlining tool in professional use and it publishes the two figures that matter: motor speed and blade material. Corded is not a compromise here - a lineup is a stationary job.
- Material
- Carbon steel T-blade
- Made in
- Not published
- Refill
- Proprietary to the maker
- Warranty
- 2 years
- Assumed service life
- 2,600 uses
The arithmetic: 260 uses a year x 10 years of assumed service life = 2600 uses.
What it gets right
- Published 7,200 SPM magnetic motor - a real figure, which most trimmers do not give
- Published carbon-steel T-blade, hardened for cutting life
- Published 14.5 oz weight and 2-year warranty
- Corded, so there is no battery to fade mid-line
Flaws
- Corded, so it is tethered - and the cord length is not published
- Magnetic motors are louder and buzz more than rotary
- Carbon steel will rust if it is left wet; it needs oiling
- No guards included at this item number - it is an outlining tool, not a clipper
The working behind the 6.6
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 8.0
- Published motor speed and blade material remove the two biggest unknowns in this category (++), corded means no fade mid-line (+), but the cord itself is the friction (-) and carbon steel needs oiling (-).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.
- What the maker publishes: 6.7
- 2 of 3 specifications a buyer would expect are published: material, warrantyLabel. Not published: madeIn. 2 / 3 x 10 = 6.7.
Axes with no published input are dropped and the remaining weights re-normalized, so a product is not punished for a category where an axis does not apply. Specifications compiled 3 September 2026 from Andis T-Outliner 04780 published motor, blade and warranty.

Wahl Professional 5-Star Detailer (8081)

Wahl 5 Star Magic Clip (8148)

Questions people actually ask
What is a T-blade for?
Cutting an edge. The blade is wide and square with teeth overhanging the housing on both sides, so you can drive a corner along a line with nothing blocking your view. The roundup covers why a clipper cannot do it.
Is carbon steel worth the maintenance?
It takes and holds a finer edge than stainless, which is why it is the professional default. It also rusts if left damp, so brushing it out and oiling it after every use is an obligation rather than a suggestion - the routine is here.
Should I zero-gap it?
Not until you can already cut a straight line. Zero-gapping moves the cutting blade nearly flush with the guard for a harder line, and it removes the margin that keeps steel off skin. Every barber who does it could already cut the line without it.
Magnetic or rotary motor?
Magnetic runs at a fixed high speed with more vibration and noise; rotary is smoother and quieter with more torque under load. Both Andis tools publish the same 7,200 SPM despite using different motor types, so for this job the difference is mostly comfort.
Does it come with guards?
Not at this item number - it is an outlining tool, not a clipper. The GTX version of the same trimmer ships with four combs if you want length capability too, and the T-blade roundup compares them.
