Hole saw DRAUMET BI-metal 27 mm — model 9032640, bi-metal construction for cutting metal and wood

Bi-metal hole saw DRAUMET BI-metal 27 mm (DRAUMET 9032640) is made of HSS tool steel with an M2 high-carbon steel cutting edge. It is designed for drilling holes in steel, stainless steel, non-ferrous metals, aluminium, wood and plastics. The tool has an M14 thread and a HEX mounting method. Cutter diameter 27 mm, cutting depth 37 mm.

Advantages

The bi-metal construction combines toughness and wear resistance for longer life compared with simple high-speed steel saws. The M2 high-carbon cutting edge provides effective metal cutting performance while the HSS body ensures strength and resistance to deformation. The M14 threaded shank with HEX mounting allows secure attachment to compatible arbors and power tools.

Suitable for

• Drilling through mild and stainless steel
• Creating holes in non-ferrous metals and aluminium
• Making openings in wood and plywood
• Cutting holes in plastic materials

How to use

Fit the hole saw to a compatible arbor or mandrel with an M14 thread and HEX mounting, tighten securely. Mark the drilling position and start at low speed to create a pilot indentation, then increase speed as appropriate for the workpiece material. Apply steady pressure, avoid side loading, and withdraw periodically to clear chips. Use cutting fluid when drilling metals to reduce heat and extend tool life.

Usage recommendations

For best results on steel and stainless steel, use appropriate cutting fluid and moderate speed. When drilling thicker metal, use incremental drilling and allow the tool to cool. Ensure the drill or driver supports an M14 threaded arbor and HEX mount before use.
