Starrett HSS Bi-Metal Fast Cut Hole Saw Review: Fast, Clean Cuts for Metal and Wood

Hole saws built for fast, clean cutting across metal and multi-material jobs, cutting down on finishing time and snagging. Tradespeople and keen DIYers benefit from reliable, repeatable results that reduce rework and save time. Is the Starrett HSS Bi-Metal Fast Cut Hole Saw the right choice for demanding workshop and site work?

⚡ At a Glance

• Cutting Quality: Fast-cut HSS teeth with a positive rake and non-binding edge deliver smooth, low-burr holes
• Best for: Tradespeople and DIYers who need repeatable holes in metal, wood and plastics
• Not ideal for: Thicker steel plates beyond 3mm or deep plunge cuts in very hard timbers

HSS tooth material paired with a 5.5 TPI positive rake tooth design enables rapid, clean cutting. Extra gullet volume helps chip evacuation while cutting up to 3mm stainless and mild steel.

Faster, smoother cuts – thanks to 5.5 TPI positive rake tooth design

A 5.5 TPI positive rake tooth geometry presents a sharper cutting angle and higher tooth engagement per revolution, reducing vibration and bite. The shape encourages continuous cutting rather than tearing, so each tooth removes material efficiently.

Quicker hole completion with cleaner edges reduces time spent on deburring and finishing, useful for repetitive on-site or workshop tasks.

Greater durability under metal cutting – with HSS bi-metal tooth material

High-speed steel teeth welded to a flexible backing combine hardness for edge retention with resilience against bending. The bi-metal construction resists heat-related wear when cutting ferrous materials.

Longer service life when working on stainless and mild steel, cutting down on frequent replacements and downtime.

Improved penetration and chip clearance – thanks to 30% extra gullet volume

Larger gullet pockets provide more space for swarf, reducing clogging and helping chips evacuate away from the cutting edge. Reduced chip build-up keeps teeth cooler and maintains cutting efficiency.

Continuous cutting through thin-walled tubes and sheet metal with less binding, making repetitive holes faster and more reliable.
