🔧 Compatible Materials & Thickness

Material	Max Thickness	Application
Stainless Steel	≤ 4mm	Industrial fabrication, kitchen equipment
Aluminum Alloy	≤ 20mm	Automotive, aerospace, structural parts
Iron / Angle Iron	≤ 20mm	Construction, structural steelwork
Cast Iron	≤ 20mm	Machinery, pipe fittings, heavy equipment

⚠️ Important Usage Precautions

1 Check that the center drill is tightly fastened before operation. Start the machine to verify concentricity. Keep the hole saw perpendicular to the metal surface at all times to avoid alloy tooth detachment. Apply cutting fluid when drilling thick metal to reduce heat and extend tool life.
2 Strictly follow the recommended drilling speed table to prevent overheating or damage to the saw teeth. Exceeding the recommended RPM may significantly shorten tool life.
3 When using a hand drill, ensure the hole saw remains perpendicular to the workpiece. For higher precision and stability, bench drill operation is highly recommended.

❓ Frequently Asked Questions

Q What materials can the TCT Alloy Hole Saw cut through?

The TCT Alloy Hole Saw is designed to drill through stainless steel (≤4mm), aluminum alloy, iron, angle iron, and cast iron (≤20mm). Its YG10X tungsten carbide teeth provide the hardness needed to handle these demanding materials efficiently.

Q What size range is available for this hole saw?

This TCT hole saw is available in a wide range of sizes from 12mm to 270mm, making it suitable for a broad variety of drilling applications across different industries and workpiece dimensions.

Q Is this hole saw compatible with standard electric drills?

Yes. The TCT Alloy Hole Saw is fully compatible with both electric drills and bench drills. It supports handheld and fixed-position operations, offering flexibility for different job site requirements.

Q Do I need to use cutting fluid when drilling?

Cutting fluid is strongly recommended when drilling through thick metal materials. It helps dissipate heat generated during cutting, reduces wear on the carbide teeth, and significantly extends the overall service life of the tool.

Q What is the maximum drilling depth of this hole saw?

The TCT Alloy Hole Saw has a maximum working depth of 20mm, which accommodates most standard metal sheet and plate thicknesses used in industrial and construction applications.

Q How can I ensure the best cutting accuracy and safety?

Always verify that the center drill is securely fastened before starting. Maintain the hole saw perpendicular to the workpiece surface throughout the operation. For maximum precision and safety, bench drill operation is highly recommended over handheld use. Always follow the manufacturer's recommended drilling speed guidelines.
