Usage and Maintenance Tips
When cutting metal or hard plastics, reduce the feed speed appropriately.
After each use, clean debris from the teeth and apply a small amount of rust-preventive oil.
If the blade shows cracks or severe wear, replace it immediately.
Do not exceed the maximum RPM indicated to avoid danger.
Check the extension rod threads regularly; replace them promptly if they become stripped.
Frequently Asked Questions (FAQ)
Q: Can I cut stainless steel tubing?
A: Not recommended. This set is primarily designed for wood, copper, aluminum, plastic, and thin sheet metal (≤1mm). Thick-walled stainless steel requires a specialized cutting blade.
Q: My drill only runs at 3,000 RPM. Can I use it?
A: Absolutely. Lower RPMs provide greater torque, delivering excellent results when cutting plastic and wood. Higher RPMs are mainly used for small engraving machines or pneumatic tools.
Q: Do the extension rods wobble?
A: Our extension rods feature an integrated hexagonal shank design. When secured with washers and screws, they are extremely stable and undergo concentricity testing before leaving the factory.
Q: Can I purchase replacement blades separately after the original set wears out?
A: Yes. Please contact customer service to purchase individual replacement blades; all sizes are available.
Summary: If you frequently need to make quick cuts inside pipes, in tight spaces, or on a variety of materials, this set of hex-shank high-speed steel saw blades with 3 extension rods will be a practical tool in your toolbox. With high RPM, high hardness, and a quick-change design, it makes repairs and DIY projects more efficient and safer.
