27.5" Closed‑Cell Foam Planer · Insulation Trimming Equipment 110V
Foam Planer main view
Product Overview

The wall with the polyurethane coating is not clean and smooth, and this tool can make the wall clean and tidy and trim corners quickly and easily. By placing its head directly on the stud, it also uses a rotating head to send itself into the wall. This minimizes the amount of work required to operate the trimmer. The planer is suitable for processing closed-cell PU foam materials and can be used in conjunction with the PU spraying machine.

Features
Planing Roller

Ultra‑Long Cutter Head

The ultra-long knife head design increases the flat area, resulting in faster work efficiency. The planing roller is equipped with diamond-shaped convex blocks for multi-point synchronous cutting, greatly improving closed-cell PU foam planing efficiency.

Drive Chain

Heavy‑Duty Support

The support point is made of extra thick aluminum plate, sturdy and durable. The chain drive maintains linear tracking, precisely matching feed speed and cutting depth, substantially improving planing flatness.

Baffle

Safety & Protection

Safety features include guards and a chain break system. The baffle locks securely, adapting to high-frequency vibration, improving operation safety and convenience.

Handles

Precision Trimming

The rotating head is designed to cut the foam to the studs without damaging them, suitable for steel or wood studs. Inboard bearings allow fast, clean corner trimming.

Ergonomic Handles

Ergonomic Handles

The double handles allow the operator to firmly hold, meeting ergonomic standards and relieving fatigue caused by single-hand operation.

Power Head & Chain

Power Head & Chain System

The power head is an electric chainsaw with correctly positioned handles. The chain break system ensures safety, while the roller chain keeps linear tracking for precise planing.

Installation Operation
Installation steps
Operation Method
  • 1. Grip the two handles of the machine firmly with both hands.
  • 2. Start by completely trimming the bottom of the wall so you can avoid running the cutter bar through a pile of trimmings.
  • 3. Do not run the cutter over the edges of the steel hangers or braces, as the power and speed needed to cut foam quickly may cause the ridged edges to tear off the cutter teeth.
  • 4. To use the cutter more easily and cleanly, run it up the wall with the cutter turning and taking a light cut.
  • 5. Use the small drill-powered cutter to trim around receptacles, hangers and other tight places.
