## Long description

Delphi Tools GLOB PREMIUM IN SITU — bi-metal hole saw designed to cut precise circular openings in a range of construction and installation materials. The saw combines a high-speed steel cutting edge with a flexible alloy body to balance wear resistance and toughness. Intended for use with compatible mandrels and drill drivers, it handles tasks such as creating holes for pipes, conduits and fixtures in metal, wood and many plastics.
Advantages
The bi-metal construction provides improved durability of the cutting teeth while retaining flexibility to resist cracking. Hardened cutting edge geometry delivers clean cuts and reduces the need for secondary finishing. The saw is compatible with standard drill mandrels and typical power drills, allowing straightforward mounting and removal. Its design supports consistent hole roundness and depth control when used with an appropriate pilot drill.
Suitable for
Cutting circular openings in sheet metal and non-ferrous metals
Creating holes in wood for fixtures, pipes and cable passages
Drilling openings in rigid and semi-rigid plastics
Installation tasks in construction, electrical and plumbing work
When it may not be suitable
This hole saw is not intended for continuous cutting of very hard tool steels, ceramic tiles, masonry or reinforced concrete; using it on these materials will accelerate wear and may damage the tool. For precision bores in delicate finishes or tight-tolerance mechanical components, a dedicated drill or reaming tool is preferable.
Key specifications
Blade material: bi-metal (high-speed steel cutting edge bonded to flexible alloy body)
Designed cutting applications: metal, wood, plastics
Compatibility: standard drill mandrels / drill drivers
Typical use: manual or powered drilling with pilot bit for guidance
How to use
Fit the hole saw onto a compatible mandrel and secure it in the drill chuck. Install a pilot bit to centre the saw and set drill speed according to the material: lower speeds for metals, medium to higher speeds for wood and plastics. Apply steady, moderate pressure and clear chips periodically to avoid overheating. For larger diameters or thick material, perform cutting in stages and maintain alignment to ensure a round, clean hole. After cutting, deburr the hole edges as needed.
What to consider before purchase
Confirm the hole saw diameter needed for your application and that it matches available mandrels
Verify compatibility with your drill’s chuck size and required pilot bit type
Assess the main materials you will cut (metal, wood, plastics) to ensure bi-metal is appropriate
Usage recommendations
Use a pilot bit and appropriate feed speed for the material, keep the cutting zone clear of chips, and allow pauses to prevent overheating when working in metal. Store the saw dry and inspect teeth before use to maintain cutting performance.
