Hole saw (bimetal HSS-Co) Abraboro 30 x 38 mm AB30030000

Abraboro bimetal HSS-Co hole saw with a 30 mm cutting diameter and 38 mm cutting depth is designed for drilling precise circular holes in metal and other hard materials. The HSS-Co bimetal construction combines high-speed steel with cobalt alloy to increase heat resistance and maintain cutting performance under heavy loads. The tool is compatible with standard arbors and can be used in hand-held drills and drill presses for sheet metal, pipes, and structural components where a clean circular cut is required.

Advantages

The bimetal HSS-Co construction provides improved wear resistance and longer tool life compared with standard high-speed steel hole saws. The 30 mm cutting diameter and 38 mm cutting depth allow through-cuts in thin to moderately thick materials while maintaining hole accuracy. Teeth geometry and bimetal brazing reduce chipping and maintain cutting speed, and the saw tolerates higher temperatures encountered during prolonged drilling in stainless steel and other tough alloys.

Suitable for

• Cutting circular holes in sheet metal and steel plates
• Drilling openings in stainless steel components
• Creating holes in pipes and tubular structures
• Use with hand-held drills and drill presses for maintenance and fabrication

Key specifications

• Cutting diameter: 30 mm
• Cutting depth: 38 mm
• Material: bimetal HSS with cobalt alloy (HSS-Co)
• Application: metal, stainless steel, and other hard materials
• Compatibility: standard drill arbors; suitable for hand-held drills and drill presses

How to use

Fit the hole saw to a suitable arbor and secure it in the drill chuck according to the arbor manufacturer's instructions. Mark the center of the hole and, if possible, use a pilot drill to ensure accurate positioning. Start drilling at low speed to establish the cut, then increase speed and apply steady, moderate pressure. Allow the tool to cool periodically when cutting hard materials; clear swarf from the hole saw teeth to maintain cutting efficiency. Use cutting fluid when drilling stainless steel or other heat-sensitive alloys to reduce heat buildup and extend tool life.

Usage recommendations

For best results, select drill speeds and feed rates appropriate for the workpiece material, keep the saw teeth clear of swarf, and use a suitable cutting lubricant on stainless steel. Inspect the tool for wear before use and replace when teeth show significant dulling to avoid poor hole quality or excessive motor load.
