Frequently Asked Questions
Is P-2 acceptable for shredding customer information?
No. A 3.8 mm strip leaves complete lines of text intact and can be reassembled without special equipment. DIN 66399 P-2 is intended for internal, non-sensitive material. For anything covered by HIPAA, GLBA, state privacy law or GDPR, the working expectation is a cross-cut machine at P-4 or better - in this range, the 260 TS C4 AO. Buy the 260.1 S4 for volume, not for protection.
How is this different from the 260.1 S2?
The knife width, and everything that follows. The S4 cuts 3.8 mm (P-2) and takes 22-24 sheets at 80 gsm with an 80-litre bin in a 41-inch cabinet. The S2 cuts 1.9 mm (P-3), takes 12-14 sheets, has a 60-litre bin and stands 33 inches tall. The S2 also runs oil-free and does not accept optical media; the S4 does accept CDs, DVDs, Blu-ray and floppies.
Can it shred CDs and DVDs?
Yes - Kobra rates the 260.1 S4 for CDs, DVDs, Blu-ray discs and floppy disks alongside paper, credit cards and chip cards, at O-2 for optical media. Feed discs one at a time and not mixed in with a stack of paper. Hard drives, USB sticks and phones are outside what any paper shredder will do safely; those need a dedicated media destroyer.
How many sheets in practice?
Kobra quotes 26-28 sheets at 70 gsm and 22-24 at 80 gsm. Typical US 20 lb bond sits around 75 gsm, so 24 sheets is a realistic everyday figure. Stapled bundles count as their full thickness and folded sheets count twice. Consistently feeding at the maximum wears the knives faster than the time saved is worth.
Does it need oiling?
Kobra publishes an oil-free cutting system for the 260.1 S2 but does not make that claim for the S4, so treat this one as a machine that should be lubricated. Oil the head at bin changes during heavy use. Kobra excludes damage caused by insufficient lubrication from its warranty, and shredder oil is inexpensive next to a cutting head. Use purpose-made shredder oil, not a household lubricant.
How often will the 80-litre bin need emptying?
Strip waste is bulky and does not settle, so the bin fills by volume well before it fills by weight. In an office running the machine daily for bulk clearance, expect two or more bag changes a week; in lighter use, every week or two. The bin-full interlock stops the cutters, which prevents waste packing back up into the head.
