Hole saw bimetal Abraboro HSS-Co 22 x 38 mm AB30022000

Hole saw bimetal Abraboro HSS-Co 22 x 38 mm AB30022000 is a bimetal circular cutter designed for making precise round openings in metal and a variety of other materials. Constructed from high-speed steel with cobalt alloy (HSS-Co), this hole saw offers improved heat resistance and prolonged cutting edge life compared to standard HSS. With a 22 mm cutting diameter and 38 mm cutting depth, it is suited to tasks that require narrow, accurate holes for installations, piping, electrical boxes and HVAC penetrations.

Advantages

The bimetal construction combines a wear-resistant cutting edge with a resilient body, delivering consistent performance on stainless steel, mild steel, non-ferrous metals and some softer construction materials. Cobalt alloy in the cutting teeth increases thermal stability during sustained drilling, reducing premature dulling. The 22 mm diameter provides a compact hole size for fittings and conduit entries while the 38 mm depth allows for through-cuts or recessed penetrations in many common panels and pipes.

Suitable for

• Cutting round holes in sheet metal and metal panels
• Creating openings for plumbing fittings and pipe penetrations
• Drilling precise access holes for electrical boxes and cable glands
• HVAC installation penetrations and ductwork access

Key specifications

• Cutting diameter: 22 mm
• Cutting depth: 38 mm
• Material: high-speed steel with cobalt alloy (HSS-Co)
• Type: bimetal hole saw for metal and multi-material use
• Recommended use: powered drilling with pilot bit or arbor

How to use

Mount the hole saw on a compatible arbor with a suitable pilot bit and secure it in a drill or drill press. Align the pilot bit to the intended center point, start drilling at low speed to create the initial guide, then increase speed and apply steady pressure appropriate for the workpiece material. Use cutting lubricant when working with stainless steel or other heat-sensitive metals to reduce friction and prolong tool life. Clear chips frequently to avoid clogging and overheating.

Usage recommendations

For best results, operate the hole saw at moderate speeds recommended for HSS-Co tooling, maintain steady feed pressure, and use appropriate cutting fluid on harder metals. Inspect the teeth before use and replace the hole saw when signs of excessive wear or tooth damage appear to ensure clean, accurate cuts.
