Hole saw for metalworkers and woodworkers promising fast, clean holes with minimal finishing. Save time on site and reduce sanding thanks to specialised tooth geometry. Is Starrett HSS Bi-Metal Fast Cut Hole Saw the right addition to a professional toolkit?
⚡ At a Glance
- • Cutting Quality: Extra cobalt HSS teeth with a 5.5 TPI positive rake and a non-binding clean edge design for smoother, faster cuts
- • Best for: Tradespeople and serious DIYers needing reliable holes in stainless steel, mild steel, wood and plastics
- • Not ideal for: Cutting metals thicker than 3mm or jobs that require an included arbor and pilot drill
Fast Cut bi-metal saws pair cobalt HSS teeth with positive rake geometry to reduce binding. Suited to cutting up to 3mm stainless and mild steel, and deeper 41mm hole depth where required.
Speed on the job – With extra cobalt HSS tooth material
Extra cobalt HSS tooth material combined with a 5.5 TPI positive rake reduces cutting resistance and keeps teeth sharper under load. The tooth form evacuates material more quickly than standard designs.
Faster through-cuts reduce time per hole and lower the frequency of blade changes, especially useful for repetitive site work.
Cleaner holes with less burr – Thanks to non-binding clean edge design
Non-binding tooth geometry and a sharp, positive-rake profile minimise tearing on entry and exit. The blade shape encourages a cleaner kerf and reduces burring.
Cleaner edges mean less deburring and finishing, saving time when fitting pipework, conduits, or fixtures.
Versatile material compatibility – With bi-metal construction
Bi-metal construction bonds high-speed steel teeth to a flexible backing so the blade resists heat and fatigue. The combination allows cutting through stainless steel, mild steel, wood, plastics and plaster.
One blade handles a broad range of tasks across plumbing, electrical and carpentry work, reducing the need for multiple specialised saws.
