Hole saw Abraboro bimetal HSS-Co 44 x 38 mm AB30044000

Hole saw Abraboro bimetal HSS-Co 44 x 38 mm AB30044000 is a cutting tool designed for drilling clean, round holes in metal and other hard materials. Manufactured from high-speed steel with cobalt alloying, this bimetal hole saw provides improved wear resistance and higher heat tolerance compared to standard HSS cutters. With an outer diameter of 44 mm and a working depth of 38 mm, it is suitable for use with compatible arbors and pilot drills in both professional and home workshop environments.

Advantages

The cobalt-alloyed HSS construction increases cutting life and helps maintain edge hardness at elevated temperatures. Bimetal tooth construction combines flexibility with toughness to reduce breakage and extend service life under intermittent cutting conditions. Precision-ground teeth enable consistent hole quality and reduced burr formation, while the 38 mm depth allows cutting through relatively thick sheets and thin-walled components. The saw is compatible with standard holders and pilot drills, facilitating quick setup and replacement.

Suitable for

• Drilling round holes in steel and non-ferrous metals
• Cutting holes in stainless steel with careful feed and cooling
• Creating openings in thin-walled tubing and sheet metal
• Workshop and maintenance tasks requiring accurate circular cuts

Key specifications

• Material: high-speed steel (HSS) with cobalt alloying
• Type: bimetal hole saw with precision-ground teeth
• Outer diameter: 44 mm
• Working/cutting depth: 38 mm
• Suitable for use with compatible arbors and pilot/drill bits
• Intended cutting materials: steel, stainless steel (with appropriate technique), non-ferrous metals, and other hard materials

How to use

Install the hole saw on a compatible arbor and secure a suitable pilot drill to guide the cut. Mark the centre of the intended hole, start drilling at low speed to establish the pilot, and then increase speed and apply steady, even pressure. Use cutting lubricant or coolant when working with ferrous materials to reduce heat build-up and prolong tool life. Periodically withdraw the saw to clear chips and inspect the teeth. After completing the cut, deburr the hole edge if necessary.

Usage recommendations

For optimal results, use a robust arbor and a correctly sized pilot drill; select lower speeds and steady feed when cutting stainless steel or other hard alloys, and apply cutting fluid to manage temperature and extend the saw's service life.
