Hole Saw for Metal GEKO G39689 — 50 mm Carbide-Tipped with Titanium Drill Bit

Hole Saw for Metal GEKO G39689 — 50 mm Carbide-Tipped with Titanium Drill Bit is a circular cutting tool designed for creating clean, round openings in metal substrates. The set includes a 50 mm carbide-tipped hole saw and a titanium-coated pilot drill bit that ensures accurate centring and initial penetration. Intended for use with standard hand-held drills and drill presses, this hole saw is suitable for working with sheet metal, thin-walled profiles and similar metal components encountered in plumbing, HVAC, electrical installation and light fabrication.

Advantages

The carbide-tipped cutting edge provides enhanced wear resistance and maintains cutting performance when working with ferrous and non-ferrous metals. The titanium-coated pilot drill bit offers improved durability and reduced friction for smoother starts and better guidance. The tool’s geometry promotes efficient chip removal and stable cutting, helping to reduce chatter and produce round holes with consistent diameter. Compatibility with common drill arbors and chucks makes the hole saw straightforward to fit and use.

Suitable for

• Cutting holes in sheet metal for pipe and conduit penetration
• Creating access openings in HVAC ductwork and panels
• Making cable and wiring entry points in electrical enclosures
• Light fabrication tasks involving thin-walled metal profiles

Key specifications

• Nominal diameter: 50 mm
• Cutting material: carbide-tipped teeth for improved wear resistance
• Pilot drill: titanium-coated for reduced friction and enhanced durability
• Intended materials: sheet metal and thin-walled metal profiles
• Recommended machines: hand-held drills and drill presses with compatible arbor

How to use

Secure the pilot drill in the arbor and fasten the hole saw according to the drill manufacturer’s instructions. Mark the cutting point on the workpiece and clamp the material to prevent movement. Start drilling at low speed to allow the pilot bit to establish a centred hole, then increase speed moderately while applying steady, even pressure. Use cutting fluid when working with thicker or harder metals to reduce heat and extend tool life. After cutting, withdraw the hole saw carefully and clear any chips from the teeth before the next use.

Usage recommendations

Use appropriate personal protective equipment, such as safety glasses and gloves. Select a drill and arbor that provide sufficient torque and stability. For best results on stainless steel or harder alloys, use cutting fluid and moderate feed rates to avoid overheating the carbide tips.
