EXTRACUT T.C.T. Circular Saw Blades for Aluminium are purpose-built for fast, burr-free cutting in aluminium extrusions, aluminium sheets, and non-ferrous metals such as copper and brass. Featuring a premium 65Mn spring steel body fitted with OKE high-grade tungsten carbide tips ground to a TCG (Triple Chip Grind) tooth geometry, these blades produce clean, mirror-like finishes without material loading or edge burrs. Available in diameters from 4” (100 mm) to 20” (500 mm) with tooth counts from 40T to 120T, EXTRACUT aluminium-cutting blades are the professional choice for window & door fabricators, aluminium profile processors, and general metalworking shops.
Key Features
- Premium 65Mn Steel Core — High-tensile spring-steel body delivers exceptional rigidity and dimensional stability, resisting warping even under prolonged high-speed cutting cycles.
- OKE High-Grade Tungsten Carbide Tips — Fine-grain carbide teeth with a specialised rake angle for non-ferrous metals offer superior wear resistance and maintain a keen cutting edge over extended service life.
- TCG (Triple Chip Grind) Tooth Geometry — The alternating flat-top and trapezoidal tooth pattern shears cleanly through soft, gummy non-ferrous metals, eliminating material adhesion (loading) and producing a smooth, burr-free surface finish.
- Negative Rake Angle Design — Optimised negative rake reduces tooth grab and vibration when cutting aluminium, ensuring safer operation and prolonging carbide tip life.
- Precision Ground & Tensioned Plates — Each blade is laser-straightened, dynamically balanced, and tension-rolled to achieve run-out within ±0.08 mm for whisper-quiet, accurate cuts.
- Wide Diameter Range — 4”–20” (100–500 mm) diameters with 40T–120T configurations cover thin-gauge sheet work up to thick-walled structural aluminium extrusions.
- Corrosion-Resistant Surface Treatment — Rust-inhibiting coating on the steel body extends storage life and maintains appearance in humid workshop conditions.
Applications
Ideal for aluminium window and door frame cutting, aluminium curtain-wall fabrication, aluminium sheet and plate processing, copper and brass bar/stock cutting, non-ferrous metal profiling, and general light-metal fabrication. Suitable for sliding compound mitre saws, panel saws, circular cold saws, and CNC aluminium cutting centres with appropriate arbor sizes. Always use adequate lubricant/coolant and adhere to recommended RPM limits for optimal tool life and finish quality.
