Starcke supplies the bulk of our sanding disc and belt range, spanning three abrasive materials and multiple hole patterns sized to match specific sanding machines rather than a one-size-fits-all disc.
Single-Hole vs Multi-Hole Discs
Starcke's 178mm discs are supplied single-sided without a centre hole pattern, designed for Bona Edger and other 178mm-compatible edging sanders. The 150mm range, by contrast, comes in 8+1 hole (eight holes plus a centre hole) versions built specifically for Festool sanders' dust extraction ports, as well as single-hole and hole-free variants for other machines. Getting this match right affects dust extraction efficiency, not just whether the disc physically fits.
Abrasive Materials in the Starcke Range
Starcke's discs use different abrasive grains depending on size and application. The 178mm edging discs are silicon carbide, formulated with an open-coat design that resists heat build-up and clogging during continuous edging work. The sanding belts are available in both zirconia (built to handle more heat and pressure, suited to heavier belt-sander work) and aluminium oxide (a versatile option valued for aggressive, time-saving cuts on the initial passes of a job).
Belt Sizing and Construction
Starcke belts come in two widths — 200x750mm (8") and 250x750mm (10") — sized to match different belt sander models, with grits from 24 through to 120 covering everything from initial cutting-back to final finishing passes. The belts themselves are joined using kevlar tape, in either a straight or finger-type joint, which affects how smoothly the join runs over the floor during sanding.
Common Questions About Starcke Products
How do I know which hole pattern I need?
Match it to your machine — 8+1 hole discs are built for Festool sanders' dust extraction, while single-hole or hole-free discs suit other edging sanders such as Bona Edger. Using the wrong pattern reduces dust extraction efficiency even if the disc still fits.
What's the difference between zirconia and aluminium oxide belts?
Zirconia generally handles more heat and pressure, making it suited to heavier, sustained belt-sander use. Aluminium oxide is a versatile all-rounder, particularly effective for aggressive initial cutting passes.
Should I choose 200x750mm or 250x750mm belts?
This depends entirely on your belt sander's specification — check your machine's compatible belt size before ordering, since the two widths aren't interchangeable.
What grit should I start with for a heavily worn floor?
A coarse grit (16–24) is typical for stripping back a heavily worn or old finish, working progressively finer through the medium grits before finishing.
