Airway Sisal Buffing Wheel Polishing Wheel for Mild Steel Mirror Finish

A buffing wheel that fits your spindle without a bushing, and cuts mild steel before the colour goes on, is a made-to-order item. This one is built to your 4 numbers: diameter, bore, thickness and hardness. Stitched natural sisal layers carry the cutting power that lifts scratches out of mild steel; a ventilated airway core lets heat leave at the bore instead of soaking into the face. Cotton sits in the same build, the colour is natural beige, and the carton is export grade. It is the cut-and-pre-polish stage, one step before the mirror.

Three things go wrong with a buffing wheel bought off the shelf. The bore is not your spindle, so it goes on with a bushing and runs out of true. The face is either hard enough to burn a colour into mild steel, or soft enough to smear scratches instead of lifting them. By the time the face is worn flat, your size has left the catalogue.

This wheel does not start from a stock size. It is an airway sisal buffing wheel: natural sisal fibre laid into multiple stitched layers and clamped at a ventilated core, supplied in natural beige. Sisal is the cutting fibre, the one that lifts scratches and pre-polishes mild steel; the cotton in the build holds those layers in place. The core is the other half: it keeps air moving through the middle while the wheel runs.

What makes it yours is 4 numbers: diameter, bore, thickness and hardness. Send those and the disc is built to them, so a 1-pass change on the spindle needs no adapter. It mounts on the 3 mounting families: bench grinder, polishing lathe, buffing machine.

Each wheel leaves in an export-grade corrugated carton, made in China, in 1 colour. Given four numbers, the second box behaves like the first, and the operator stops re-learning pressure at every change.

What a stock-size sisal wheel does not give you:

• Stitched sisal layers — multiple layers of natural sisal, packed and stitched rather than pressed into one pad, so the cut sits at the face.
• Ventilated airway core — the centre is open to airflow, so heat leaves at the bore rather than soaking into the face and loading it with compound.
• Two fibres in one build — sisal supplies the cut, cotton holds the body together: 2 materials, 1 disc, no backing plate.
• Four dimensions made to order — diameter, bore, thickness and hardness are specification lines, not matching after delivery.
• Bore cut to your spindle — 3 mounting families covered (bench grinder, polishing lathe, buffing machine) with the bore you ask for, so nothing is bushed to fit.
• Hardness as a choice — soft for driving colour into mild steel, hard for taking material down: 1 spec sheet covers both.
• Dense layer stack — tightly stitched layers resist deformation and wear, so the face flattens with use instead of the disc losing shape.
• One job, done first — scratch removal and pre-polish before the final colour, the stage where sisal earns its place.
• Natural beige — 1 colour only, so a reorder looks like the previous box on the rack.
• Export-grade carton — the wheel travels flat and square rather than pressed oval under other freight.

The usual choice is between a stock wheel that almost fits and sending the work out. A wheel built to four numbers is the third option.

• Your bore, not a bushing. The 4 numbers you send are the numbers the disc is built to, so it seats the way the old one did and runs true on the first pass.
• Two stages off one face. Scratch removal and pre-polish sit before the colour stage; doing both with sisal means fewer changes in the spindle and less compound on the bench.
• Heat leaves at the centre. A ventilated core lets a running wheel shed heat instead of glazing its own face, which is what keeps a mirror finish even across a panel.
• Reorders match. 1 colour and one spec sheet, so box two is built like box one and the operator does not recalibrate pressure.
• Hardness is a decision, not luck. Soft for colour, hard for cutting down: the same wheel format covers both, which keeps 1 mounting in the spindle instead of two.
• Wear goes into the face. Dense stitched layers resist deformation, so the disc stays round and the replacement interval stops depending on how the wheel was stored.

Whatever your spindle takes — there is no stock size to match. Measure the wheel you are replacing for diameter, bore and thickness, then tell us the hardness you want: those 4 numbers are the whole specification.

No — it takes it to pre-polish, which is the stage before the colour. Sisal is the cutting fibre: it lifts scratches out and leaves an even surface. The mirror itself is put on by a softer wheel with compound afterwards.

A softer, finer wheel with compound, for colour. Keep this airway sisal wheel on scratch removal and pre-polish; using it as a colour wheel wastes a face that is built to cut.

Airflow. The ventilated core lets heat leave at the bore instead of trapping it in the face, which is what stops the sisal glazing over and loading with compound during a long run.

Yes. Hardness is one of the four made-to-order dimensions. A softer build suits driving colour into mild steel; a harder build suits taking material down before finishing.

If the bore matches, yes. The wheel is bored to your spindle and is built for the 3 mounting families we supply: bench grinder, polishing lathe and buffing machine — no adapter needed.

No. Natural beige is the only colour, and there are no fixed sizes — diameter, bore and thickness are always made to order, which is why 1 order and the next one behave the same.

Export-grade corrugated carton, and four numbers from you: diameter, bore, thickness and hardness. Those four lines are enough for us to build the wheel and quote the order.
