Hole saw for metal GEKO 20 mm with titanium drill bit, carbide cutting tip

GEKO 20 mm hole saw for metal with a titanium-coated center drill and a carbide cutting tip is designed to cut clean, precise 20 mm holes in metal sheets and profiles. Intended for use with standard drills and drill presses, the tool combines a durable carbide tooth geometry with a corrosion-resistant titanium-coated pilot drill to improve centering and prolong life when working with steel, stainless steel, and non-ferrous metals. The compact diameter and robust construction make it suitable for professional and hobby applications where a consistent circular opening is required.

Advantages

The carbide cutting tip ensures higher wear resistance and predictable cutting performance on a range of metal thicknesses, reducing the need for frequent sharpening. The titanium-coated center drill improves pilot hole accuracy and resists overheating during high-speed drilling. The hole saw body is built to withstand the torque loads typical for metal cutting, while the 20 mm diameter provides a versatile size for pipe penetrations, fastener access, and wiring passages. The overall design balances cutting efficiency with tool longevity.

Suitable for

• Drilling 20 mm holes in thin to medium-thickness metal sheets and profiles
• Plumbing and HVAC installations for pipe and conduit passages
• Electrical installations requiring circular openings for conduit or cable glands
• General metalworking and maintenance tasks in workshops and construction sites

Key specifications

• Cutting diameter: 20 mm
• Center drill: titanium-coated pilot drill for improved centering and heat resistance
• Cutting edge: carbide (widiowa) tipped for increased wear resistance
• Material suitability: steel, stainless steel, aluminum and other common metals (depending on thickness)
• Compatibility: fits standard drill chucks and drill press arbors with appropriate arbor/mandrel

How to use

Secure the hole saw to a compatible arbor or mandrel and tighten according to the arbor manufacturer’s instructions. Mark the center of the desired hole on the metal surface. Use the titanium-coated center drill to establish a pilot hole and align the saw, applying steady pressure and moderate drill speed. Use cutting lubricant when drilling harder steels to reduce friction and extend tool life. After cutting through, withdraw the saw carefully and remove the slug from the cylindrical body using a punch or the arbor's ejection function if provided.

Usage recommendations

Operate at appropriate speeds for the material being cut and use cutting fluid for steel and stainless steel. Secure the workpiece firmly and wear suitable personal protective equipment including eye protection and gloves. Avoid excessive side pressure that can damage the carbide tip; allow the tool to cut at its own rate with steady, controlled feed.
