Starrett 51mm Bi-Metal Hole Saw
This 51mm bi-metal hole saw is built for electricians, plumbers and metal fabricators who need clean holes in steel, aluminium or wood. The hardened high-speed steel teeth resist heat and wear during repeated cutting. It fits standard arbors for quick changes on corded or cordless drills. Buyers who need carbide-tipped teeth for abrasive materials should look elsewhere.
Fast-cut tooth geometry reduces binding
The variable-pitch tooth pattern clears chips faster than constant-pitch designs, so the saw runs cooler and finishes holes with less pressure. This means fewer broken teeth and less downtime swapping dull cutters on the job site. The saw is not impact-rated, so it must not be used in percussion or hammer mode.
Standard arbor mount installs in seconds
The saw threads onto any common 1/2-20 arbor; no special tools or adapters are required. The most common error is running the drill above the recommended speed for the material, which overheats the teeth and welds chips to the gullets. Always use cutting fluid in metal and clear chips frequently.

Questions about this item
When will the bi-metal teeth on this 51 mm hole saw need replacing?
The bi-metal edge stays sharp through repeated cuts in steel and wood; replace it once the teeth no longer bite cleanly or the cut wanders.
What stops the saw from cutting deeper during a long session?
The 51 mm cutting depth is the fixed limit; the saw cannot go deeper regardless of run time.
How much heat builds up when the saw runs all day in a drill press?
Bi-metal construction dissipates heat efficiently, so the body stays warm rather than hot even during extended use.
