Hole saw set Abraboro AB30500000 — bimetal holesaws 19–54 mm, multiple diameters

Abraboro hole saw set AB30500000 includes bimetal hole saws in a range of diameters from 19 mm to 54 mm, offering multiple sizes for cutting round openings in wood, plastics and thin metals. The bimetal construction combines a high-speed steel cutting edge with a flexible backing steel body to improve wear resistance and extend service life under frequent use. The set is intended for general workshop, installation and maintenance tasks where different hole sizes are required.

Advantages

The bimetal design provides enhanced durability and heat resistance compared with standard carbon steel saws, reducing wear during repetitive cuts. A range of diameters from 19 to 54 mm eliminates the need for separate purchases of individual saws for common opening sizes. The saws are compatible with typical drill presses and hand drills when used with appropriate arbors, allowing versatile use in different working conditions. The cutting geometry and bi-metal edge help deliver consistent, clean circular cuts in softer metals, wood and plastic.

Suitable for

• Creating round openings for cable glands and conduits in electrical installation
• Drilling holes for plumbing and fixture mounting in wood and plastic panels
• Cutting access holes and service openings in thin sheet metal
• General workshop tasks requiring a variety of hole diameters

Key specifications

• Diameter range: 19 mm to 54 mm (multiple diameters included)
• Material: bimetal construction (high-speed steel cutting edge with steel backing)
• Suitable materials: wood, plastics, thin metals
• Intended for use with drill presses and hand drills using appropriate arbors
• Design: tooth geometry optimized for general-purpose cutting and long life

How to use

Select the hole saw diameter appropriate for the required opening and mount it on a compatible arbor or drill chuck according to the arbor manufacturer's instructions. Secure the workpiece and mark the hole center. Operate the drill at a moderate speed, applying steady pressure and cooling or clearing chips as needed when cutting metal to avoid overheating. For wood and plastics, use a lower speed for larger diameters to maintain control and reduce tear-out. After cutting, withdraw the saw and remove the core plug, taking care to clear any burrs or sharp edges.

Usage recommendations

For cutting in metals, use cutting fluid or intermittent cutting to reduce heat buildup and extend saw life. Always use appropriate personal protective equipment (eye protection, gloves) and secure the workpiece to prevent movement. Choose the correct arbor and pilot bit for stable, accurate drilling.
