This high speed steel hole saw is specially developed for metal hole drilling work. Adopting high grade 9SiCr alloy tool steel, the cutting teeth maintain good hardness and wear resistance for long-term service.
Every production step is strictly inspected to ensure cutting stability and smooth chip removal. Integrated pilot drill helps accurate positioning to avoid deviation during operation. A complete range of sizes from 20mm to 55mm supports diversified hole making demands in metal processing. Independent inner box packaging protects the cutting edge from impact.
Our HSS hole saws are crafted from premium high-speed steel, heat-treated to achieve optimal hardness and wear resistance. The variable tooth geometry reduces vibration and ensures smooth cutting, while the deep gullet design efficiently clears chips, preventing clogging and overheating. Each saw is compatible with standard arbor systems and can be used with hand drills, drill presses, or magnetic drilling machines. Below are the key technical specifications and features that set our product apart.

Frequently Asked Questions (FAQ)
1. What types of metal can this hole saw cut?
Our HSS hole saw is designed for cutting a wide range of metals, including mild steel, stainless steel, aluminum, copper, brass, and alloy steel. For hardened steel or thick plates, we recommend using a lower speed and applying cutting fluid.
2. What is the maximum thickness this hole saw can cut in one pass?
The standard cutting depth is up to 35mm. For materials thicker than 35mm, we offer extended cup versions (up to 50mm) or you can drill through in multiple passes by clearing chips.
3. Can I use this hole saw with a regular hand drill?
Yes, it is compatible with most hand drills, drill presses, and magnetic drilling machines. Ensure the drill speed is set appropriately (typically 200–600 RPM depending on diameter) to avoid overheating.
4. Do you offer custom diameters or shank types?
Absolutely. We provide customization services for diameter, shank type (hex, round, SDS-plus), and coating. Minimum order quantity may apply for custom sizes, but we are flexible for OEM/ODM partners.
5. How do I prevent the hole saw from overheating?
Use cutting oil or a suitable lubricant during drilling. Reduce the feed pressure if you notice smoke or discoloration. Our variable tooth design helps dissipate heat, but proper cooling is always recommended.
6. What is the typical lead time for bulk orders?
For standard sizes, lead time is 7–15 days after order confirmation. For custom orders, it may take 15–25 days depending on complexity. We ship from major Chinese ports (Tianjin, Ningbo, Shanghai, Guangdong).
7. Can I get a sample before placing a large order?
Yes, we provide free samples (buyer pays shipping) for quality evaluation. Sample orders are usually processed within 3–5 working days.
8. Does your company have quality certifications?
Yes, we are certified under ISO9001 and ISO14000. Our products are manufactured in a facility with strict quality control procedures, and we can provide a certificate of conformance upon request.
