Hole saw for tradespeople and DIYers, engineered for fast, clean holes in metal, wood and plastics. Starrett HSS Bi-Metal Fast Cut Hole Saw promises quicker cuts and neater edges, so installers feel confident on demanding jobs. Will the build and tooth design stand up to regular workshop use?
⚡ At a Glance
- • Cutting Quality: Extra cobalt HSS tooth material combined with a 5.5 TPI positive-rake tooth form for faster, smoother cutting.
- • Best for: Tradespeople and serious DIYers who need reliable cutting through metal, wood and plastics.
- • Not ideal for: Very thick steel plate or masonry work where specialist cutters are required.
Extra cobalt HSS teeth and a positive-rake 5.5 TPI tooth form promote faster cutting with a cleaner edge. Suited to up to 3mm stainless and mild steel with a 41mm hole saw depth.
Faster, cleaner holes - thanks to extra cobalt HSS teeth and 5.5 TPI positive-rake design
Extra cobalt high-speed steel tooth material increases hardness at the cutting edge, while the 5.5 teeth-per-inch positive-rake profile bites aggressively and reduces chatter. The combination lowers cutting resistance and helps maintain a cleaner kerf.
Quicker hole cutting with neater edges reduces finishing work, making repetitive tasks such as installing pipework or conduit less time-consuming.
Capable on thin metals - with bi-metal construction handling up to 3mm steel
Bi-metal construction bonds HSS teeth to a flexible body, preserving tooth hardness while allowing some flex under load. Rated for cutting stainless and mild steel sheets up to 3mm and tubes with 3mm wall thickness.
Confidence when cutting sheet metal and tubing for plumbing or electrical runs, eliminating the need to swap to specialist metal-only blades for these thicknesses.
Better chip clearance and depth - with 30% extra gullet volume and 41mm depth
A larger gullet volume helps evacuate swarf more efficiently, reducing binding and overheating during cutting. The hole saw depth of 41mm allows deeper penetration than many shallow designs, with recommended 13mm depth for softer materials.
Cleaner operation in wood and plastics and the ability to cut deeper holes when routing through thicker panels or longer tubing sections.
