Power-tool accessories for tradespeople promising long-life, deep cutting performance. Clean, repeatable holes help installers and joiners stay productive and reduce rework. Is the Starrett Deep Cut Hole Saw up to the task for heavy-duty metal and timber work?
⚡ At a Glance
- • Cutting Quality: Smooth, deep cuts thanks to 51mm cutting depth and sharp teeth
- • Best for: Tradespeople needing precise holes in sheet metal, tubes and soft timber
- • Not ideal for: Hardwood, very hard metals and stone applications
Increased 51mm cutting depth handles metal thicker than 3mm and wood up to 51mm. Bimetal HSS with extra cobalt teeth gives enhanced heat and wear resistance for longer life.
Deep, consistent holes – with 51mm cutting depth
A deep-cut design increases saw depth to 51mm (2 inches), enabling single-pass holes through many materials. Deep cuts require arbors with an extended-length pilot drill to reach full depth.
Achieve one-pass holes in tubes and timbers up to 51mm thick, reducing repeat passes and keeping job times down.
Durable, fast cutting – with bimetal HSS and extra cobalt teeth
Constructed from high-speed steel with added cobalt in the teeth, delivering improved heat resistance, corrosion resistance and wear performance. Sharp tooth geometry encourages smooth cutting with light vibration.
Maintain cutting speed and tooth life across demanding tasks, so fewer replacements are needed and performance stays consistent.
Versatile compatibility – with wide diameter options and common arbors
Available in diameters from 19mm to 210mm and designed to fit many manufacturers' power tools. Note that arbors and pilot drills are not included and deep cuts require extended-length pilot drills.
Cover a broad range of hole sizes for plumbing, electrical and joinery work while matching existing drill setups when the correct arbor is used.
✨ The 4 Key Reasons for Starrett Deep Cut Hole Saw
- Cobalt-reinforced teeth – Resist overheating for longer continuous cuts without dulling
- Wide diameter range – Cover jobs from 19mm to 210mm hole sizes
- Suitable for varied materials – Cut metal, plastic, acrylic, fibreglass and formica cleanly
- Deep 51mm capacity – Make single-pass holes through tubes and timbers up to 51mm
📋 Technical Details at a Glance
- Category: Hole saw for power drills
- Material: Bimetal high-speed steel with extra cobalt HSS teeth

❓ Frequently Asked Questions
Q: Can the saw cut stainless steel (inox)?
A: Yes, the saw is specified as suitable for metal inox and non-ferrous materials, using the cobalt HSS teeth for effective cutting.
Q: Are arbor and pilot drill included?
A: No, the deep-cut hole saw does not include the arbor or pilot drill; arbors with extended-length pilot drills are required for full 51mm depth.
Q: What sizes are available?
A: Sizes range from 19mm up to 210mm, covering the most commonly used hole saw diameters for trade work.
🏆 Our Verdict
Tradespeople and installers who need repeatable, deeper holes in sheet metal, tubes and soft timbers will find the saw well suited to demanding on-site tasks. The combination of a 51mm cutting depth and cobalt-reinforced HSS teeth supports longer life and steady cutting performance. Although an upfront investment, durable construction and fewer replacements make it cost-effective over time.
