Makita 199146-8 Autofeed Screwdriver Attachment for the DFS452

Makita 199146-8 is an autofeed attachment for collated screws for the DFS452 drywall screwdriver. It takes screws of Ø3.5 - 4.0 mm and 25 - 55 mm in length, and has depth adjustment. It measures 225 x 49 x 120 mm and weighs 0.4 kg.

The Y suffix

The stock number ends in Y, which in the shop's system marks a second-hand unit. The condition of the individual item is confirmed before ordering.

What the attachment does

Screws arrive on a plastic collated strip and the attachment feeds them one at a time. The operator only presses and releases - no reaching into a box of screws and no holding a screw between fingers. Boarding a ceiling, that is the difference between a hundred screws an hour and several hundred.

Depth adjustment

Depth is set once and every screw sinks the same. On plasterboard that is not a convenience: too deep tears the paper and the screw loses its hold, while too shallow leaves a head that shows through the filler. The correct setting is flush with the board, dimpled slightly.

Which screws fit

Ø3.5 - 4.0 mm and 25 - 55 mm long, collated. Outside those limits the strip either will not enter or the feed jams. Length is chosen by board thickness - the screw needs at least 10 mm into the stud.

For the DFS452 only

The attachment is machine-specific. It mounts on the nose of the screwdriver and works with its gearing - it is not universal. If your machine is a different Makita model, check article 199146-8 against its parts list.

A note on the number

The article is written 199146-8 - six digits, a hyphen and a check digit. The shop's stock record has it run together as 1991468, which is a transcription error: in that form the number does not exist in Makita's catalogue and cannot be found by searching.

Maintenance

Keep the feed mechanism clear of plaster dust. Dust packs between the feed wheel and the strip and the feed starts to skip - the commonest reason an attachment stops working long before it is worn out.
