Hole Saw 20mm Bi-Metal Cutter for Wood, Plastic & Metal

A 20mm bi-metal hole saw built for cutting neat, consistent holes in wood, plastic and metal. With a maximum cutting depth of 38mm, it suits a wide range of installation, repair and general workshop jobs where a clean round cut is needed.

Used for electrical work, plumbing and mechanical jobs, this cutter is handy when fitting pipework, cable routes, access points and small component openings. It also suits DIY repairs, garage work and workshop use where sheet material, timber or plastic needs a precise hole rather than a rough opening. Electricians, plumbers and mechanics will all find it useful for regular drilling tasks across mixed materials.

The bi-metal construction gives the cutter the strength needed for repeated use, especially when moving between different materials on site or in the workshop. The 20mm size is useful for smaller openings where accuracy matters, while the 38mm cutting depth gives enough reach for many common fitting and maintenance tasks. For buyers who need one cutter for more than one job, the mixed-material cutting ability helps reduce the need to keep swapping between separate wood and metal hole saws. That makes it a practical option to keep close to hand in a tool bag, van or drill kit for everyday use.
