Hole saw for metal GEKO G39680 — 16 mm carbide-tipped with titanium pilot drill, pack of 100

GEKO G39680 is a 16 mm carbide-tipped hole saw designed for cutting precise holes in metal. Supplied with a titanium-coated pilot drill bit, this pack of 100 units is intended for repeated use in metalworking operations where stable 16 mm through-holes are required. The carbide tip provides hardness and wear resistance for cutting into steel and non-ferrous metals, while the pilot drill improves centring and repeatability when used with standard drills and drivers.

Advantages

The carbide-tipped cutting edge delivers longer life and consistent hole quality compared with high-speed steel alternatives. The titanium-coated pilot drill reduces friction, improves centring and extends the service life of the starter bit. Supplied in a bulk pack of 100, the set reduces the need for frequent reordering for production environments and maintenance teams. The 16 mm diameter offers compatibility with common fasteners and fittings, enabling efficient installation and assembly work.

Suitable for

• Drilling 16 mm holes in steel sheets and profiles
• Creating openings for fasteners, rivets, and pipe penetrations
• Maintenance and repair work in workshops and service departments
• Production and assembly lines requiring repeatable hole sizes

Key specifications

• Cutting diameter: 16 mm
• Tip material: carbide-tipped cutting edge
• Pilot drill: titanium-coated centre drill for improved wear resistance
• Intended material: metals including mild steel and non-ferrous alloys
• Pack quantity: 100 hole saws with pilot drills

How to use

Select a compatible drill or driver capable of delivering steady rotational speed and adequate torque for metal cutting. Secure the workpiece to prevent movement and mark the drilling location. Fit the hole saw and its pilot drill into the drill’s arbor, clamp firmly, and position the pilot on the mark. Start at low speed to allow the pilot drill to establish the centre, then increase speed and apply steady pressure while keeping the drill perpendicular to the work surface. Clear chips periodically to avoid heat buildup and inspect the hole saw for wear; replace if cutting performance decreases.

Usage recommendations

Use cutting fluid or lubricant when drilling thicker or harder metals to reduce heat and extend tool life. For best results, match drill speed and feed rate to the metal type: lower speeds for stainless steel or harder alloys, higher speeds for thin mild steel and aluminium. Always wear appropriate eye and hand protection and secure the workpiece before drilling.
