The 28PG drives twenty-eight 3mm chisel tip needles at 2200 blows per minute, a slower, heavier stroke than the 19-needle tools. It breaks up thick paint systems, pack rust and scale on structural steel and plate, and the wider bundle covers more surface per pass.
Pick the 28PG when the coating is heavy or the area is large; for light rust and tight detail, the smaller 19PG is easier to control.
Run across failing paint, the 28PG needle bundle fractures the film and lifts it with the rust beneath, leaving a peened steel surface with texture for the next coat to key into. Light, steady pressure is all it needs; leaning on the tool slows it down.
Dress for it: hearing protection, eye protection and a respirator matched to the coating are part of the job, and the work area needs cleanup after scaling.
The same 28PG body runs needles, a 1/2" square chisel holder or a 5/8" hex chisel holder. The hex version takes the long reach range of 1", 2" and 4" chisels and the 4", 8" and 12" scraper heads, so one tool can strip floor tile as well as scale steel.
Choose the needle scaler for rust and coatings, a chisel scaler for spatter and slag, or one of the two kits to carry both setups.

Novatek rates the 28PG at 7.5 cfm (220 lpm) of air, and the tool is meant to run at 90 psi at the inlet. Use a 3/8" bore airline, keep the run to about 50' where you can, and put a filter, regulator and lubricator in the line so the air reaches the tool clean, dry and oiled.
It is the 28PG chisel scaler with a 5/8" hex chisel holder instead of the 1/2" square one. The hex holder takes Novatek's long reach chisels and scraper heads, which suits tile, mastic and thick deposit removal. The needle kit with Super Scraper adds 5/8" hex chisels in 1", 2" and 4" widths.
It ships with 28 x 3mm x 7" chisel tip needles. With the matching needle holders it takes 65 x 2mm needles or 19 x 4mm needles.
The 28PG hits harder with a wider bundle at 2200 bpm and weighs 8.3 lbs; the 19PG is lighter at 5.7 lbs with a quicker 3000 bpm stroke. Use the 28PG for heavy coatings and large areas, the 19PG for lighter rust and longer overhead work.
Yes. Put three drops of light machine oil into the air inlet before you start, and run an inline lubricator if you have one. Novatek's manual notes that running its scalers without air preparation could void the warranty.
No. Novatek says the 28PG is not built for explosive atmospheres or for work close to flammable materials, and a steel needle striking steel can spark. Wear hearing and eye protection and a dust mask suited to the coating you are removing.
