Edge Sander

An edge sander is a low-profile disc sander built to finish the strip of floor a drum sander cannot reach — along walls, under toe-kicks, in closets and on stairs. It runs a spinning abrasive disc close to vertical surfaces at floor level. The catalog lists 7 models from brands including American Sanders, Jet, Werkmaster and HTC.

How it works

The motor drives an angled abrasive disc housed under a low guard, with handles set so the operator works stooped or kneeling at the perimeter. The disc's slight tilt presents a working edge to the floor; the operator sweeps in overlapping arcs, matching the grit sequence used on the field of the floor so the border blends invisibly. Dust collection runs through a bag or vacuum port, and disc changes step through the same coarse-to-fine progression as the drum passes.

Types & variants

Stair and detail edgers: Compact formats sized for treads, landings and tight closets.
Radial arm and specialty edgers: Extended-reach variants for under radiators and cabinetry overhangs.

How the industry sizes it

Edge sanders are sized by disc diameter and under-clearance: the standard machines handle open perimeter runs, while smaller detail formats work stairs and closets. The choice follows the drum sander — the edger must match the field machine's grit sequence and cut rate so the border does not read differently under finish.

Applications

Sanding floor perimeters after drum sanding the field
Refinishing stair treads and landings
Closet and alcove floors too small for a drum sander
Blending borders under toe-kicks and radiators
Detail removal of finish and stain at wall lines

Safety & operation

The disc grabs at wall contact — a two-hand grip and controlled arcs prevent kickback swings into baseboards.
Wood dust is combustible; bags are emptied often and stored outside the building, per NFPA wood dust guidance.
Older painted floors may carry lead-based coatings; EPA RRP practices apply in pre-regulation housing.
Kneeling work at disc level calls for eye, hearing and respiratory protection as standard.

Standards & certifications

EPA · 40 CFR Part 745 (RRP): Lead-safe practices when sanding painted surfaces in older housing.
NFPA · 664: Combustible wood dust fire prevention.

Frequently asked

Why not sand the whole floor with an edger?

The disc cuts in arcs and shows swirl if used on open field. It exists to finish the border the drum machine leaves; the drum's straight-line cut does the field.

How does the border blend with the field?

By matching grits pass for pass — each drum grit is followed at the perimeter with the same edger grit, so the scratch pattern under the finish is consistent wall to wall.

What marks do edgers leave and how are they avoided?

Swirl and dish marks from staying in one spot or pressing too hard. Constant overlapping motion, fresh abrasive and light pressure keep the border flat.
