Heavy-duty hole saw blade designed to cut clean, deep holes in metal and wood, ideal for trades and workshop tasks. Dependable longevity and aggressive cutting reduce time on-site. For jobs requiring 51mm depth and cobalt-reinforced teeth, is Starrett Deep Cut Hole Saw the right choice?
⚡ At a Glance
- • Cutting Quality: Smooth, deep cuts through metal, fibreglass and plastics with reduced vibration and consistent tooth engagement
- • Best for: Tradespeople and experienced DIYers cutting pipework, metal panels and retrofit openings
- • Not ideal for: Hardwood, very hard metals and stone where tooth geometry will struggle
Bimetal HSS construction with extra cobalt HSS teeth and a 51mm cutting depth. Suited to metal over 3mm thickness, tubes with walls greater than 3mm, and wood up to 51mm.
Deep, single-pass cuts - thanks to 51mm cutting depth
Increased hole saw depth of 51mm allows the blade to engage more material in one pass, but requires an arbor with an extended length pilot drill for full-depth performance. Deeper cup profile reduces the need for multiple staged cuts.
Cut thicker pipes and timber up to 51mm without switching accessories, saving time on site and in the workshop.
Longer tooth life - with bimetal HSS and extra cobalt HSS teeth
Bimetal construction bonds high-speed steel teeth to a tougher backing for shock resistance, while cobalt alloy on the teeth improves heat resistance and wear performance during prolonged cutting.
Keep sharper cutting edges over extended runs, reducing blade changes and downtime when tackling multiple holes.
Wide material compatibility - with sharp tooth geometry
Sharp tooth form and HSS composition are designed for inox (stainless), non-ferrous metals, cast iron, fibreglass, plastics, acrylic, formica, plaster and suspended floors, while avoiding extremely hard materials.
Use the same blade for a range of workshop and site tasks, from metal panel work to fitting fixtures, limiting the need to swap tools.
✨ The 4 Key Reasons for Starrett Deep Cut Hole Saw
