## Summary description

Abraboro OTWORNICA BIM 54 mm is a bi-metal hole saw with a 54 mm cutting diameter and 8% cobalt composition designed for drilling holes in metals and other hard materials. The BIM construction combines high-speed steel teeth with a flexible backing for durability and resistance to heat; suitable for metalworking, plumbing and electrical installation tasks where reliable hole cutting is required.

## Long description

Abraboro OTWORNICA BIM 54 mm — cobalt 8% is a bi-metal hole saw designed for creating clean circular holes with a 54 mm diameter in metals and other hard materials. The tool combines high-speed steel cutting teeth with a flexible backing to balance cutting performance and toughness. The 8% cobalt alloy increases heat resistance and edge life compared with standard high-speed steels, making the saw suitable for repetitive drilling in demanding environments such as metal workshops and on-site installations.
Advantages
The bi-metal construction delivers a combination of hardness and flexibility that reduces tooth breakage and extends service life under higher temperatures. A 54 mm cutting diameter and uniform tooth geometry provide consistent hole quality with reduced burr formation. The 8% cobalt content improves wear resistance and maintains cutting performance when drilling into stainless steel, alloyed steels and other tougher materials. The hole saw is compatible with standard arbors and can be used with hand-held drills and drill presses, offering versatility for different workflows.
Suitable for
Drilling holes in carbon steel and stainless steel
Creating circular access points in metal enclosures and panels
Plumbing and heating installations requiring pipe or conduit openings
Electrical installations for junction boxes, switches and outlets
Workshop and maintenance tasks requiring reliable metal cutting
Key specifications
Cutting diameter: 54 mm
Material system: bi-metal (high-speed steel teeth with flexible backing)
Alloying: 8% cobalt in the cutting edge for improved heat and wear resistance
Intended materials: steels, stainless steels and other hard metals; also suitable for some non-ferrous materials
Compatibility: suitable for use with standard hole saw arbors, hand-held drills and drill presses
How to use
Secure the hole saw to a compatible arbor and attach it to an appropriate drill or drill press. Mark the center of the hole and, if necessary, start with a pilot drill to ensure accurate positioning. Use steady, moderate feed pressure and maintain appropriate cutting speed for the material being drilled; reduce speed when cutting stainless or hardened steels. Apply a suitable cutting lubricant or coolant when drilling metals to reduce heat build-up and prolong tool life. After completing the cut, clear chips from the saw and inspect the edge before further use.
Usage recommendations
For best results when drilling stainless or alloyed steels, use lower rotational speeds and apply cutting fluid. Avoid excessive side loading and allow the saw to cool between extended cuts to preserve tooth geometry and maximize service life.
