Product Description

The 6-Piece HSS Saw Blade Set is the ideal solution for intricate cutting tasks where a full-sized saw would be too bulky. The set includes five graduated blade diameters and a specialized 3.17mm mandrel arbour for secure mounting to your rotary tool. Each blade is heat-treated for superior edge retention and precision-ground to ensure straight, accurate cuts. Whether you are building architectural models, trimming plastic enclosures for electronics, or working with soft sheet metal, this kit provides a professional finish with minimal material waste.

Key Features

Durable HSS Construction: Made from strong high-speed steel for long-lasting sharpness and resistance to wear.
Precision Cutting: Ideal for fine cuts in aluminum, brass, and timber with high accuracy and speed.
Universal Shank: The 1/8" mandrel fits most rotary tools, including Dremel and standard electric drills.
Compact Versatility: Includes multiple sizes to handle different cutting depths and project requirements.
Low Friction Design: The 0.8mm slim profile reduces binding and heat buildup during high-speed operation.

Technical Details

Surface Treatment: Typically finished with a protective coating to prevent rust during storage.
Teeth Geometry: Optimized for high-RPM material removal without binding.
Safety Feature: Designed to operate safely up to 20,000 RPM when properly secured.

Prototyping and Engineering Tips from Robogears

Mandrel Installation: When mounting a blade, ensure the arrow on the blade matches the rotation direction of your tool. Tighten the center screw firmly, and ensure the mandrel is inserted as far into the tool's chuck as possible to prevent vibration.
Control Your Speed: For plastics and PVC, use a lower RPM setting. If the speed is too high, the friction will melt the plastic rather than cutting it, which can gum up the blade teeth.
Soft Metals Only: While these blades can cut aluminum and copper, do not attempt to cut steel, iron, or stone. Hard materials will instantly dull the HSS teeth and could cause the thin blade to shatter.
Lubrication: When cutting thin aluminum, a tiny amount of cutting oil or WD-40 on the blade will prevent the soft metal from sticking to the teeth, resulting in a much cleaner edge.

Package Includes

5 x HSS Circular Saw Blades (22mm to 44mm)
1 x Mandrel / Arbor (3.2mm Shank)

Disclaimer

High-speed cutting tools are dangerous. Always wear safety goggles and hand protection. Ensure your workpiece is securely clamped before starting the cut to avoid the blade "grabbing" or jumping.
