## Long description

AWTools OTWORNICA BIMETAL HSS-Co 8% 27 mm Black Line hole saw is a bimetal cutting tool designed for precise circular holes in metal and mixed materials. Manufactured from HSS-Co high-speed steel alloy with 8% cobalt, this 27 mm diameter saw offers improved wear resistance and higher heat tolerance compared with standard high-speed steel. The tool is intended for use with compatible arbors in workshop, construction and maintenance environments where accurate, repeatable holes are required.
Advantages
The bimetal construction combines a durable high-speed steel cutting edge with a flexible backing, providing resistance to chipping and extended tool life. Cobalt alloying increases hardness at elevated temperatures, reducing blade wear during prolonged cutting in steel and other hard materials. The 27 mm diameter and Black Line finish help maintain cutting stability and visibility, while compatibility with common arbors ensures straightforward integration into existing tool setups.
Suitable for
Cutting holes in mild and stainless steels
Making openings in sheet metal, pipes and ducts
Installing electrical boxes and conduit penetrations
General maintenance and repair work requiring circular cuts
Key specifications
Cutting material: bimetal with HSS-Co alloy containing 8% cobalt
Nominal diameter: 27 mm
Designed for use with standard hole saw arbors and drills
Finish: Black Line surface treatment for reduced glare and identification
Suitable for metal and mixed-material cutting applications
How to use
Fit the hole saw to a compatible arbor and secure it to a drill or drilling machine with appropriate power and speed range for metal cutting. Mark the centre point of the desired hole, use a pilot bit if available to stabilize the cut, and start drilling at moderate speed with steady, even pressure. Apply cutting lubricant when working with thicker or harder metals to reduce heat and prolong tool life. Clear swarf regularly to avoid binding and allow the tool to cool between long cuts.
Usage recommendations
For best results, use cutting fluid when drilling steel or stainless materials, select a drill with sufficient torque for a 27 mm hole saw, and ensure secure clamping of the workpiece. Replace the hole saw if rounded teeth or excessive wear are visible to maintain cut quality and safety.
