HSM SECURIO B24 1/32 x 7/16 with External Automatic Oiler - HSM17854

The HSM SECURIO B24 1/32 x 7/16 in with External Automatic Oiler (HSM17854) cuts 0.78 x 11 mm particles of 8.6 mm², placing it in DIN 66399 class P-6, one step above the P-5 machines most offices buy and one below the 1 x 5 mm P-7 model. It ships with HSM's external automatic oiler, which matters at this cut size because a 0.78 mm head clogs with dust quickly when left dry. It suits professional teams with a written P-6 requirement and a shared shredder.

P-6 B24 with oiler at a glance

• P-6 at 0.78 x 11 mm, full classification F-3 | P-6
• External automatic oiler included
• 6 sheets per pass at 80 g/m²
• About 339 sheets of waste in the 9.2 gal (35 L) bin
• Takes staples and paper clips; not cards or discs

Is 0.78 x 11 mm really P-6?

Yes, and the point is often misreported. P-6 has two tests: an area of 10 mm² or less and a width of 1 mm or less. At 0.78 mm wide and about 8.6 mm², this cut passes both. A 1.9 x 15 mm particle is P-5 even though it is longer, because P-5 allows up to 30 mm² and has no 1 mm width test. Note what P-6 is not: it is not an NSA listing. The 11 mm length is more than twice the 5 mm NSA maximum, and only the 1 x 5 mm B24 appears on the January 2026 EPL.

The oiler's job on a P-6 head

Dust builds between the discs much faster at P-6 than at P-4. Without oil, a machine rated for six sheets can drop to three or four and begin to jam. The external oiler doses the block automatically, so the upkeep happens even when no one owns the machine. Refills are an ongoing purchase; use HSM cutting-block special oil only.

The 610 W drive, shared with faster B24 versions, is specified for continuous operation and handles the fine head comfortably at six sheets. At 395 x 317 x 605 mm the cabinet is deskside, and at about 54 dB(A) idle it is quiet. Rated figures come from HSM datasheet 1785111, the EU equivalent of US part 1785113O.

Choosing among nearby SECURIO models

• B24 1/32 x 7/16 in without oiler: the same P-6 cut for less, if one person will oil it reliably.
• B24 1/16 x 5/8 in: P-5 at 9-11 sheets, takes cards and keeps the lifetime roller warranty.
• B24 1/32 x 3/16 in: P-7 at 1 x 5 mm and the B24 version on the NSA/CSS EPL, at 4 sheets.
• B32 1/32 x 7/16 in with oiler: P-6 and an oiler with a 12.2 in throat and 21.7 gal bin.

Who should choose it

Pick it if a client security schedule or internal classification says P-6, the shredder is shared, and you want the smallest machine that meets the rule. Skip it for everyday office paper, for cards, CDs or plastic badges, or if you value the lifetime roller warranty, which you give up by moving above P-5. The source gives no verified US machine warranty term for this model, so confirm it before ordering if it matters.
