Circular Saw Blades for uPVC & Timber Window Installation

Precision circular saw blades for uPVC, timber and sheet materials used in window and door installation. Clean cuts, reduced melting, and long-life performance trusted by UK glazing professionals.

About Our Circular Saw Blades

Every blade in this collection is selected for the specific cutting demands of window and door installation. Whether you are cutting uPVC profiles, timber frames, plywood sheets or aluminium trims, these blades deliver clean, accurate cuts with minimal finishing required.

Key features across the range include carbide-tipped teeth for long service life, optimised tooth geometry that reduces heat build-up (preventing uPVC melting), and low-vibration designs for cleaner edges on frames and sills.

Compatible with all major trade circular saws including Bosch, Makita, DeWalt, Festool and Milwaukee.

How to Choose the Right Blade

Fine-tooth trim blades (80+ teeth) — Best for uPVC trims, beading and finishing cuts where a smooth edge is essential. High tooth count gives a clean cut with no burrs or melting.

General-purpose blades (48–60 teeth) — Good all-rounders for timber frames, battens and sheet materials. Suitable for ripping and crosscutting in softwood and hardwood.

Multi-material blades — Designed to cut uPVC, timber and aluminium without changing blades. Ideal for window fitters who switch between materials throughout the day.

Plywood and sheet blades — High tooth count with alternate-top-bevel (ATB) grind for chip-free cuts in plywood, MDF and laminated panels.

Trade Tip

Mark your blades with tape to track which ones are dedicated to uPVC — using a timber-dulled blade on plastic causes melting and rough edges.

Frequently Asked Questions

Which blade is best for cutting uPVC without melting?

Use a fine-tooth blade (80+ teeth) designed for plastics. The higher tooth count spreads the cutting load, reducing friction and heat build-up that causes melting. Run the saw at a moderate speed and let the blade do the work.

Can I use the same blade for timber and uPVC?

Multi-material blades are designed for exactly this. They use a tooth geometry that handles both timber and uPVC cleanly. However, for the best finish on uPVC trims, a dedicated fine-tooth plastic blade will always give a superior result.

What bore size do I need?

Most trade circular saws use a 30mm bore. Some compact saws use 20mm or 16mm. Check your saw's specification before ordering. Many blades include a bore reduction ring for compatibility.

How often should I replace my blade?

Replace when you notice increased resistance, rough cut edges, or burning marks on uPVC. A sharp blade should cut cleanly with minimal force. For professional daily use, expect to change blades every 2–4 weeks depending on material and volume.
