Built to Grip What Other Kits Spin On

Each of the 20 bits does one job, made from steel hard enough to cut the screw instead of polishing it.

65-HRC M2 High-Speed Steel

Tempered to 63–65 HRC, so the cutting edges cut hardened and stainless screws instead of rounding off on first contact.

20 Dedicated Pieces

Ten burnishing drill bits and ten matched extractors, each on its own shank. No working tip ever sits inside your drill chuck.

Reverse-Spiral Bite

Left-hand flutes wedge deeper as the screw resists, sending your drill's torque straight into backing the fastener out.

Universal 1/4-Inch Hex Shank

6.35mm hex shanks lock into any cordless drill chuck or quick-change holder with no slip, and each is laser-engraved #1–#10.

How It Works in Two Bits and Under a Minute

1. Burnish a Clean Cone

1. Burnish a Clean Cone

Chuck the matching numbered burnishing bit, set the drill to reverse on low speed, and mill a symmetrical seat into the stripped head in about 10 seconds.

2. Lock the Extractor In

2. Lock the Extractor In

Swap in the extractor with the same number. Its reverse-spiral flutes wedge into the fresh cone and grip harder as you turn.

3. Pick the Right Size

3. Pick the Right Size

Ten graduated sizes cover 2mm electronics screws up to 12mm automotive bolts, so one case handles whatever strips next.

Description

Why separate bits matter: Double-ended flip kits clamp one working tip inside the chuck while you use the other end, which crushes the flutes before they reach the screw. Every Cosari bit has its own hex shank, so both the drill tip and the extractor tip arrive sharp.

How to get a perfect bite: Set a standard variable-speed drill to reverse and its low gear, under 400 RPM. Push straight down with steady pressure for both steps. You'll feel the moment the flutes lock in, and then the screw starts turning.

What it handles: Stripped, rounded, and snapped Phillips, Torx, Allen, and slotted screws in wood, steel, aluminum, and brass, from 2mm laptop screws up to 12mm bolts. Not intended for Grade 10.9+ high-tensile bolts or titanium fasteners.

Saved a Saturday smart-lock install in under a minute

One soft brass door-hinge screw stripped completely smooth and turned a quick 15-minute door alignment into a two-hour headache. Tried the rubber band trick and needle-nose Vise-Grips—nothing could touch it since the head was countersunk flush. Ran the Dr#4 bit slow in reverse on my cordless drill to clean out a neat little cone, swapped to the Ex#4 bit, leaned in, and it backed right out on the first revolution.

Finally single-ended bits that actually fit magnetic hex holders

Whoever decided cheap hardware-store extractors should be double-ended clearly never used a standard 1/4-inch magnetic bit extension—the sharp reverse tip always jams against the magnet. Having all 20 Dr# and Ex# bits laser-etched #1 through #10 on separate single-ended hex shanks is night and day better. Pulled four rounded-out stainless screws off my cedar deck steps and the edges still look brand new.

The #10 micro bit rescued my $1,400 gaming laptop

My stomach dropped when the tiny factory M.2 SSD standoff screw cammed out into a perfect silver circle while upgrading storage. Regular extractor sets don't go anywhere near that small. Put the #10 bit into a manual precision hex driver, pressed straight down turning counterclockwise, and felt it bite immediately. Paid for the entire kit in ten seconds.

Night and day vs the gold infomercial extractors

I had an older 4-piece gold-coated set from TV that literally ground itself smooth on a single exterior screw like it was made of cheddar. These matte HSS bits actually cut steel. Pulled three 15-year-old rusted Phillips screws out of an aluminum storm door frame without slipping once or scratching up the trim around the holes.

Follow the low-RPM rule and they bite like a pitbull

Important tip for anyone frustrated with extractors: DO NOT put these in an impact driver and hammer the trigger. Put them in a standard cordless drill set to Speed 1 in REVERSE around 200–300 RPM with steady downward pressure. Once I slowed down and let the burnishing tip form a clean pocket, the spiral bit grabbed a broken patio chair bolt effortlessly. Docked half a star only because the case latch is snug at first.

Bought a second set for my truck toolbox

Used the #2 and #3 sizes to back out two seized license-plate bracket bolts and a stripped fender liner screw on my F-150. Having ten graduated sizes instead of guessing between four vague bits means you always get exact contact inside the stripped head. Keep one case in my rolling garage chest and ordered a second one at 50% off for the truck.

Got a flush pocket-clip Torx screw out of my folding knife

Stripped a tiny blue-Loctited T6 screw on a titanium pocket knife clip. Warmed it slightly with a hair dryer, used the #9 burnishing bit by hand to clean the burrs, and the #9 extractor walked it right out without marring the scale. Hard to find one kit that handles tiny EDC hardware and heavy timber screws equally well.

Cheaper than one hour of shop labor

Snapped the Phillips wings off two carburetor float-bowl screws while rebuilding an old snowblower. The #7 Dr/Ex pair milled a neat dimple and spun both screws out clean without touching the threads in the casting. Solid high-speed steel and zero wobble in my DeWalt chuck.

Clear #1 to #10 markings save a ton of squinting

At 62 my garage eyesight isn't great, so having Dr#1–#10 and Ex#1–#10 clearly marked in dedicated slots makes matching the drill tip to the extractor foolproof. Backed out six painted-over cabinet hinge screws during our laundry room remodel in ten minutes flat.

Handled countersunk deck screws that Vise-Grips couldn't reach

Replacing rotted fascia boards and ran into half a dozen coated deck screws with the heads spun into smooth bowls below the wood surface. Dr#5 and Ex#5 pulled every single one out without splitting the surrounding cedar. Great kit to have on the shelf before disaster strikes.

Frequently Asked Questions

Do I run the drill forward or in reverse?

Reverse (counterclockwise) for both steps. The burnishing bit cuts its cone in reverse, and the extractor bit grips and backs the screw out in reverse. Keep the drill under 400 RPM.

Can I use an impact driver?

No. Use a standard variable-speed cordless or corded drill on its low gear. Impact hammering can chip hardened tips and damage soft fasteners.

Will it work on hardened deck screws and stainless steel?

Yes. The 63–65 HRC M2 high-speed steel cut through hardened deck screws, standard stainless, brass, and carbon steel in our testing. It is not designed for Grade 10.9+ high-tensile bolts or titanium fasteners.

What sizes do #1 through #10 cover?

The #1 bits handle bolts up to 12mm (1/2 inch), and the #10 bits handle screws as small as 2mm, including laptop and electronics screws. Sizes in between cover common wood, hinge, and machine screws.

Are these double-ended bits?

No. All 20 bits are single-ended, with a 1/4-inch (6.35mm) hex shank on one end and one working tip on the other, so the chuck never clamps onto a cutting edge.

What if it doesn't work on my screw?

You're covered by the 30-day money-back guarantee. If it doesn't extract your stripped screw, or a flute chips or dulls under the 2-year warranty, you get a full refund or a free replacement set.
