Description

The KOBRA 300 HS-6 is a compact P-7 shredder that cuts paper and film into 0.8 x 5 mm particles (4 mm² each) through a 12 in (300 mm) opening, inside a cabinet only 17 in (41 cm) wide. It is listed by name on the NSA/CSS Evaluated Products List for paper shredders. The natural buyer is a government office or cleared contractor that has to keep the shredder inside a small controlled room.

KOBRA 300 HS-6 key points

P-7 F-3 to DIN 66399 / ISO 21964, 0.8 x 5 mm particle
Named on the NSA/CSS EPL for paper shredders (April 2026 revision)
5-6 sheets at 70 g/m², 5 sheets at 80 g/m²
Twin 24-hour continuous-duty motors, 920 W combined
22-gallon (85-liter) steel cabinet on casters, 83 lb

Two motors in a narrow cabinet

A P-7 cut demands a lot of torque for a small machine. KOBRA's answer on the 300 HS-6 is to split the load between two motors, each with its own metal chain and steel gearing, rated together at 920 W (1 1/2 HP on the US datasheet). Both run continuously with thermal protection, so there is no cool-down timer to work around. The carbon-hardened knives back out automatically when a stack is too thick.

The result is a footprint of 17 x 12.25 in, which is narrower than the other P-7 cabinets in this lineup. Where floor area in a secure room is tightly allocated, that width is often the deciding factor.

What the EPL listing covers

At 4 mm², the 300 HS-6's particle sits under the 5 mm² maximum for P-7, and its dimensions satisfy the 1 mm x 5 mm limit in NSA/CSS Specification 02-01. The April 2026 EPL revision lists the Kobra 300 HS-6 under Marquis Business Systems. A P-7 rating alone never counts as NSA approval, and the list is revised from time to time, so have your security officer confirm the current edition.

Daily handling and consumables

Electronic eyes start and stop the cutters, and Energy Smart standby powers the machine down between jobs, with optical indicators showing its status. Opening the cabinet door halts the knives. The unit ships assembled on its cabinet with a power cord and manual. Waste bags are not supplied, and oiling is manual on this model; KOBRA cutting-head oil comes in 1-liter bottles sold by the case of 24.

Weighing the 300 HS-6 against nearby KOBRA models

KOBRA 270 TS HS-6 AO: same 0.8 x 5 mm particle with a touch panel, built-in automatic oiler and a 29-gallon bin; 4-5 sheets at 70 g/m².
KOBRA 260 HS2-6: P-7 on a 1 1/2 HP chassis rated for up to 10 sheets, in a wider 20 in cabinet.
KOBRA 300.1 C4: a P-4 machine with a 12.2 in opening that takes 20-22 sheets at 70 g/m², for personal data rather than classified paper.

Who should pick the 300 HS-6

It fits a secure room with limited floor space, a written P-7 or NSA/CSS 02-01 requirement and modest daily volume. Light enough to roll between rooms, it suits one cleared user or a small team. It is a poor choice as the main shredder for a busy department, since five sheets a pass is slow going for general paperwork, and it accepts no cards or optical media.

Frequently Asked Questions

Is the KOBRA 300 HS-6 NSA approved?

It is listed. The April 2026 revision of the NSA/CSS EPL for paper shredders names the Kobra 300 HS-6 under Marquis Business Systems, and its 0.8 x 5 mm particle meets the 1 mm x 5 mm limit of Specification 02-01. Because the EPL changes periodically, confirm the current revision before you buy against a compliance requirement.

How many sheets can the 300 HS-6 take per pass?

Five to six sheets of 70 g/m² paper, or five sheets of 80 g/m² paper. US 20 lb bond is close to the heavier figure, so plan on five. Counting sheets rather than guessing avoids most stoppages on a P-7 head.

Does the KOBRA 300 HS-6 fit in a small secure room?

That is what it is designed for. The cabinet measures 17 x 12.25 x 32.5 in (41 x 31 x 83 cm) and weighs 83 lb, and it sits on casters so it can be moved between rooms. It is narrower than the other P-7 cabinets in the KOBRA lineup.

Will Legal-size paper go into the 300 HS-6?

Yes. The 12 in (300 mm) opening takes US Letter and Legal without folding, and Tabloid can be fed on its short edge. Sheet ratings are given for A4, so reduce the stack slightly with larger sheets.

Does the 300 HS-6 need oil?

Yes. This model has no automatic oiler, so the cutting head is lubricated by hand. A P-7 head loses capacity and jams more easily when dry. KOBRA sells cutting-head oil in 1-liter bottles; if you want oiling handled automatically, look at the KOBRA 270 TS HS-6 AO.

Can the KOBRA 300 HS-6 destroy CDs or credit cards?

No. It is rated for paper and films only, and it has no separate optical media slot. Rigid plastic can damage the fine knives, so discs and cards need a different machine.
