1. Neiko 01925A — the all-rounder for a home shed
The Neiko is the one we’d put in most drawers, and it’s the cheapest here. You get five spiral-flute extractors — the tapered, reverse-threaded bits that dig in as you back them out — matched to five left-hand drill bits, and that pairing is what earns it top spot. The left-hand bits are made to drill anticlockwise, so on a screw that isn’t seized solid the bit alone often grabs the metal and spins the broken piece straight out before you’ve picked up an extractor. When it doesn’t, you’ve already drilled the pilot hole and the matching extractor is sized to drop into it.
The extractors are an alloy, softer than the hardened steel a trade set uses, and there are only five sizes, so it’s not the kit for a stud snapped deep in an engine block. For the broken screws and sheared bolts a home shed throws up — a rusted deck screw, a stripped hinge, a snapped-off tap — the range covers it, and the two-tools-in-one setup gets there with the least fuss. (Joel: the two-in-one is what sells this one — you drill the pilot hole and back the screw out with the one cheap kit, no trade money for a job that comes up twice a year.)
2. GEARWRENCH 84787 Bolt Biter — the buy-once set
If you’d rather buy once, the GEARWRENCH Bolt Biter is the best-made set here. Instead of a threaded taper that can snap off inside the hole, these four extractors use tapered cutting edges along the side and tip that shear into the fastener as they turn — a design GEARWRENCH rates for far longer life than a standard easy-out. The hex base takes a spanner or a socket, and it’s drill- and impact-driver-rated, so you can bring real turning force without the extractor being the first thing to snap. They’re bi-directional too, so the same bit that backs a ruined bolt out can also tighten a good one up.
It sits second only because it’s the leanest kit — four extractors and no drill bits, so you supply your own to cut the pilot hole. It’s dearer than the Neiko for fewer pieces. What you’re paying for is a set that takes an impact driver without shattering and carries the maker’s lifetime warranty, which makes it the one to own if you hit stuck fasteners often enough to want more than a cheap extractor under them. (Matt: an extractor snapping off inside the hole turns a bad afternoon into a nightmare — the tougher steel is the whole point.)
3. Bosch BSPE6D — the one with the widest range
The Bosch is the biggest kit here — twelve pieces, six spiral-flute extractors paired with six matched drill bits, covering the widest span of screw and bolt sizes of the three. If you don’t yet know what you’ll be pulling out, or you want one box that handles everything from a small stripped machine screw up to a broken coach bolt, this is the set with a size for it. The extractors are heat-treated carbon steel, and their gripping threads are rolled rather than machined — a cold-formed finish that comes out tougher and holds more evenly than a cut thread.
It lands third on value; the build itself is fine. It’s the dearest set by a clear margin, the carbon steel isn’t as tough under an impact driver as the GEARWRENCH’s high-strength steel, and for most people it’s more kit than a couple of broken screws a year calls for. Buy it if the range is the thing you want — a full ladder of sizes from a name you know — more than you want the lowest price or the single toughest tool. (Matt: the matched bits and the spread are the draw; you’re paying for never being caught without the right size.)
How to get a broken screw out
An extractor is only as good as the hole you drill for it. Start by centre-punching a dimple in the middle of the broken fastener so the drill bit doesn’t wander off the edge. Then drill a pilot hole straight down the centre — if your set has left-hand bits, use one and run the drill in reverse, and there’s a fair chance the bit grabs and winds the screw out on its own. If it doesn’t, seat the matching extractor in the hole and turn it anticlockwise with a tap wrench or a spanner; the flutes or cutting edges bite deeper as the fastener resists, until it backs out.
Rust is what makes most of these jobs stubborn, so treat it before you drill: flood the screw with penetrating oil and give it ten minutes to creep into the threads. It won’t back the screw out on its own, but it loosens the seize enough that the extractor has something to turn against instead of a welded lump. Keep everything square, too: an extractor leaned to one side is the classic way to snap the tip off inside the hole, and a broken extractor is far harder to shift than the screw ever was. And know the limits — if the head’s still on the bolt but rounded so a socket just spins, that’s a different tool; a bolt extractor set grips the outside of the head instead.
Warranty and what you’re covered for
Only the GEARWRENCH carries a warranty worth the name — GEARWRENCH backs its Bolt Biter extractors for life. That cover runs through authorised sellers, so it’s worth confirming who a listing ships from before you lean on it. The Neiko and the Bosch don’t advertise the same lifetime cover; treat those two as consumables that earn their keep the first time they rescue a job. Whichever you buy, Australian Consumer Law may still entitle you to a repair, replacement or refund if a tool turns up faulty or isn’t of acceptable quality, whoever sold it.
The verdict
You want one set that covers the broken screws a home shed throws up: the Neiko 01925A. The extractors and the matched left-hand drill bits in one cheap box, and the left-hand bits alone spin most screws out before an extractor’s needed. Not a trade brand and only five sizes, but the right kit for the job most people face.
You hit stuck fasteners often and want to buy once: the GEARWRENCH 84787 Bolt Biter. Tapered cutting edges and a hex base that takes an impact driver without shattering, plus the only lifetime warranty here. You supply the drill bits and pay more for four pieces, but it’s the one that won’t snap off when a bolt really fights you.
You want the widest range of sizes in one box: the Bosch BSPE6D. Twelve pieces spanning small machine screws up to broken coach bolts, with matched drill bits throughout. The dearest here and not the toughest under an impact driver, but the set least likely to leave you without the right size.
Any of the three will free a broken screw. What separates them is the job you’re buying for — the occasional stripped screw, the fasteners that fight you on every job, or a full spread of sizes waiting for whatever turns up.
