Hole saw bimetal HSS-Co 19 × 38 mm Abraboro AB30019000

The Abraboro Hole saw bimetal HSS-Co 19 × 38 mm is a bimetal cutting tool designed to create clean, consistent 19 mm diameter holes up to 38 mm deep in metal and mixed materials. Manufactured from high-speed steel with added cobalt (HSS-Co), this hole saw offers improved heat resistance and wear performance compared with standard HSS tools. It is intended for use with compatible mandrels and drills in installation, maintenance and workshop environments where reliable metal cutting is required.

Advantages

The bimetal construction combines a hardened cutting edge and a flexible backing for resistance to chipping and longer service life. Cobalt alloy in the cutting teeth increases tolerance to high temperatures generated during prolonged cutting, reducing dulling and extending tool life. The 38 mm cutting depth allows drilling through thicker sheet assemblies and thin-walled pipes in a single pass. Teeth geometry is designed to produce fast cutting and efficient chip evacuation when paired with suitable cutting speeds and lubrication.

Suitable for

• Cutting 19 mm diameter holes in thin steel sheets and non-ferrous metals
• Drilling openings in pipes and conduit with thin walls
• General metal fabrication and installation tasks requiring a consistent 19 mm hole
• Applications where increased heat resistance is needed during prolonged drilling

Key specifications

• Cutting diameter: 19 mm
• Cutting depth: 38 mm
• Material: bimetal high-speed steel with cobalt (HSS-Co)
• Suitable for use with standard hole saw arbors/mandrels and power drills
• Designed for cutting ferrous and non-ferrous metals, and mixed material applications

How to use

Mount the hole saw on a compatible arbor or mandrel and secure it to a drill with adequate power and speed control. Mark the hole centre on the workpiece and, if possible, use a pilot drill or centre punch to prevent wandering. Start drilling at a moderate speed, applying steady pressure and allowing chips to evacuate; do not force the tool. For thicker or harder materials, use cutting fluid or coolant and reduce cutting speed to limit heat build-up. After cutting, remove the plug carefully and deburr the hole if required.

Usage recommendations

For optimum performance and tool life, use appropriate cutting speeds for the material being cut, apply cutting lubricant on ferrous metals, and allow intermittent pauses when cutting large volumes to avoid overheating. Inspect teeth regularly for wear and replace the hole saw when significant dulling or damage is observed.
