Description

The Kobra 240 HS-6 is the only machine in this group that appears on the NSA/CSS Evaluated Products List for Paper Shredders - it is named there as "Kobra 240 HS-6" in the January 2026 edition. It reduces a sheet to 0.8 x 5 mm particles, a 4 mm² fragment that satisfies both the DIN 66399 P-7 ceiling of 5 mm² and the NSA requirement that particles measure no more than 1 mm by 5 mm. Kobra states a single sheet becomes roughly 20,000 pieces. Everything else about the machine is subordinate to that: it takes 4-5 sheets a pass and shreds nothing but paper and film.

Key Features

Steel gears and metal chain drive. Kobra calls this the Super Potential Power Unit; it is the mechanical difference between the 240 cabinet and the lighter deskside +1/+2/+3 chassis.
24-hour continuous duty motor with thermal protection. No published duty cycle to work around during a heavy purge.
Carbon-hardened steel cutting knives. Rated by Kobra as unaffected by staples and paper clips.
Energy Smart standby with illuminated indicators. Automatic start and stop through electronic eyes, with a visible standby state.
Safety stop on bin removal. Pulling the 9.5-gallon bin stops the cutting knives; the bin slides out without lifting the cutting head.
0.8 x 5 mm high-security particle. 4 mm² - inside the 5 mm² DIN limit for P-7, and inside the 1 mm x 5 mm maximum set by NSA/CSS Specification 02-01.
On the NSA/CSS EPL for Paper Shredders. Verified against the January 2026 published list, where the model appears by name. A P-7 rating alone does not confer this - the exact model has to be listed, and this one is.
Full rating P-7 F-3. The F-3 element covers microfilm and film media alongside paper.

What's in the Box

Ships as a single assembled unit: cutting head seated on the cabinet, 9.5-gallon pull-out bin, and power cord. Kobra states this model does not require plastic bags, and none are supplied. The bin slides out without lifting the cutting head, so emptying is a one-person job.

Who Should Buy This - and Who Should Not

Buy the 240 HS-6 when the requirement comes from a classification authority rather than a preference: classified or Top Secret paper, a facility security officer's specification, an NSA EPL requirement in a contract. Nothing below P-7 satisfies that, and no amount of cross-cutting substitutes for a listed machine.

Do not buy it as a general office shredder. Four or five sheets a pass is roughly a third of what the 240 C4 manages, the 35-litre bin fills quickly because P-7 waste is bulky and light, and Kobra lists only paper and films as shreddable - no cards, no discs. For commercial confidential records the Kobra 240 C2 Turbo at P-5 does the job four times faster, and for everyday paper the Kobra 240 C4 Turbo at P-4 takes up to 26 sheets. Also note this is a small-office high-security machine: for a whole secure facility, Kobra's larger listed models such as the 300 HS-6 or 400 HS-6 are built for the volume.

Frequently Asked Questions

Is the Kobra 240 HS-6 genuinely NSA approved?

Yes, and this is one of the few shredders where the claim can be checked. NSA/CSS Specification 02-01 requires two things: a particle no larger than 1 mm x 5 mm, and the specific model appearing on the NSA/CSS Evaluated Products List for Paper Shredders. The 240 HS-6 cuts 0.8 x 5 mm and is named on the January 2026 EPL. A P-7 rating on its own would not be enough - plenty of P-7 machines are not listed.

How many sheets can it actually take?

Kobra's European datasheet gives 4-5 sheets at 70 g/m2 and 3-4 sheets at 80 g/m2; its US page quotes up to 6. We publish the lower, paper-weight-labelled figures because they are the conservative ones and because US 20 lb bond sits near 75 g/m2. Either way, a high-security head cutting 20,000 particles from a page cannot take the stacks a P-4 machine handles. Plan on four sheets.

Can it shred credit cards, CDs or badges?

No. Kobra lists only paper and films as shreddable materials for the 240 HS-6, and the full rating is P-7 F-3 - there is no O or T element. Feeding a plastic card or a disc into a 0.8 mm high-security cutting head risks damaging it, and the repair is not cheap. For card destruction alongside this machine, the Kobra 240 SC is the purpose-built option.

How often will the bin need emptying?

Often. P-7 particles are tiny and trap a lot of air, so the 35-litre bin fills in far fewer sheets than the same bin on a P-4 machine - expect on the order of 150-250 sheets. That is a genuine operational consideration in a secure facility, because bin emptying is usually a controlled procedure. Budget time for it rather than being surprised.

Does the paper have to be de-stapled first?

Kobra specifies carbon-hardened steel cutting knives for this machine, but the published shreddable materials list is paper and films only, and a 0.8 mm high-security head has far less tolerance for metal than a cross-cut one. Standard practice in secure environments is to remove staples, clips and fasteners before feeding a high-security shredder. Treat that as the rule here.

Is it quiet enough for an office?

At 61 dB(A) it is the loudest group in this range along with the other 240-series machines, and the sound is continuous because you will be feeding it small batches for a long time. It is not disruptive in a private office or a dedicated shredding room, which is where classified destruction usually happens anyway.

What is the difference between the 240 HS-6 and Kobra's larger HS-6 models?

Cutting specification is the same 0.8 x 5 mm P-7 across the HS-6 line, and several larger models - 260 HS-6, 300 HS-6, 400 HS-6 and others - also appear on the NSA EPL. What changes is scale: throat width, bin volume, motor size and sheet capacity. The 240 HS-6 is the small-office member of that family. If a whole facility shreds classified paper daily, a larger cabinet will finish the work in a fraction of the time.
