## Summary description

Bi-metal hole saw Glob Premium in situ 110/138 mm designed for cutting circular openings in various materials. The bi-metal construction combines HSS cutting edges with a flexible body for durability and reduced breakage. Suitable for use with drills and drivers for tasks such as installing pipes, conduits, or recessed fittings where precise 110 mm to 138 mm diameter holes are required.

## Long description

Bi-metal hole saw Glob Premium in situ 110/138 mm is designed to cut circular openings with diameters between 110 mm and 138 mm in a range of common construction materials. The tool pairs high-speed steel (HSS) cutting edges with a flexible, shock-resistant body to provide durability and reduce the risk of tooth breakage during use. It is compatible with drills and drivers and intended for tasks such as installing pipes, conduits, recessed fittings and ventilation components where precise round holes are required.
Advantages
The bi-metal construction provides a balance of toughness and cutting performance: HSS teeth maintain sharpness for longer while the flexible body reduces the likelihood of cracking under lateral loads. The saw is suitable for use in handheld and rig-mounted drilling equipment, offering stable cutting and reduced vibration compared with brittle alternatives. Its design supports efficient chip evacuation and consistent hole diameter across repeated cuts, improving work speed and accuracy on-site.
Suitable for
 Cutting circular openings for plumbing pipes and drain lines
 Creating holes for electrical conduits and junction boxes
 Installing recessed lights, ventilation grilles and HVAC fittings
 Work in wood, plasterboard, soft metals and some plastics (material-dependent)
Key specifications
 Cutting diameter range: 110–138 mm
 Construction: bi-metal with HSS cutting edge and flexible body
 Compatibility: for use with drills and drivers accepting hole saw mandrels
 Typical applications: circular through-holes for pipes, conduits and recessed fixtures
 Design features: chip evacuation slots and reinforced cutting rim
How to use
Secure an appropriate mandrel in your drill or driver, ensuring the arbor and pilot bit are suitable for the target material and hole diameter. Mark the center of the intended opening, position the pilot bit on the mark and start drilling at low speed to establish the guide hole. Increase speed gradually and apply steady, even pressure, allowing the saw to cut without forcing it. Periodically withdraw the saw to clear chips and prevent overheating. For through-cuts in thicker or harder materials, use lubrication or cooling where appropriate and consider incremental cutting to reduce strain on the tool.
Usage recommendations
Use appropriate personal protective equipment, including eye protection and gloves. Choose drill speeds and feed rates according to material hardness: lower speeds for metals, higher for wood and plasterboard. Inspect the saw before use for worn teeth or damage and replace it if cutting performance degrades. When working in electrical or plumbing installations, confirm that no hidden services are present before cutting.
