MBM DSH0067 2445 super micro-cut 1/32" x 3/16" (.8 x 5 mm)

The Destroyit 2445 super micro-cut takes the same 25-inch cabinet as the rest of the 2445 family and fits it with a cutting head that reduces a sheet of paper to 0.8 x 5 mm particles — 4 mm², the smallest DIN 66399 recognises. MBM states that this cut meets NSA/CSS specifications and is DOD approved. Two things follow from that head, and both matter more than the price: capacity drops to 5–7 sheets of paper only, and the warranty on the cutting shafts is one year rather than lifetime.

It is worth being precise about what P-7 means, because the term gets used loosely. DIN 66399 caps P-7 particles at 5 mm² and additionally requires the particle width to be no more than 1 mm. This machine's 0.8 x 5 mm cut satisfies both conditions with margin on the width. There is no level above P-7 in the standard — any listing quoting a higher-numbered level is describing something the standard does not define — so this is the finest cut the classification recognises.

Key Features

• P-7 super micro-cut, 0.8 x 5 mm. At 4 mm² with a sub-millimetre width, this is the top DIN 66399 tier. There is no level above P-7.
• NSA/CSS particle specification. MBM states the 0.8 x 5 mm cut meets NSA/CSS requirements and that the machine is DOD approved. See the FAQ below for what to verify before relying on this for classified destruction.
• Paper only. Unlike the cross-cut 2445 models, MBM lists no staples, clips, cards or media for this variant. That is a deliberate consequence of the fine cutting head.
• Same footprint as its siblings — 9.5-inch throat, 9-gallon bin, 0.5 HP motor, 53 lb — so it drops into the same space as a standard office unit.
• Automatic cut-off when the cabinet is opened or the bin is full, photocell start/stop, automatic reverse, and zero-energy sleep after 30 minutes.

Specifications

What's in the Box

Assembled cabinet with the 9-gallon shred bin and operating instructions. Shred bags are not included. Because P-7 output is extremely fine, most sites choose to line the bin.

Who Should Buy This — and Who Should Not

This machine exists for material where reconstruction is a real adversarial threat rather than a compliance formality: classified and controlled unclassified information, defence and intelligence contractors, research organisations protecting pre-publication data, and legal teams handling material under protective order. If your requirement is written as a particle size rather than a DIN level, this is the model in the 2445 family that meets it.

Do not buy it as a general office shredder. Five to seven sheets of loose paper with no staples and no clips is a genuinely restrictive way to work, and every stapled document has to be stripped by hand first. The one-year shaft warranty is a material downgrade from the lifetime coverage on the cross-cut models, so the total cost of ownership is not comparable. If your policy is satisfied by P-5, the DSH0065 version of this identical cabinet gives you 6–8 sheets, staples, clips, credit cards and a lifetime shaft warranty for considerably less.

Running Costs and Care

Super micro-cut shafts need oiling more attentively than coarser heads, and the operating instructions supplied with the machine set out the interval MBM expects. Skipping it is the fastest way to shorten the life of a component that carries only a one-year warranty on this variant. Bags are effectively mandatory: P-7 output behaves more like dust than confetti and will escape an unlined bin. Plan on emptying more often than the sheet count suggests, because the waste is very low in density.
