⚡ At a Glance
- • Cutting Quality: Smooth, fast cuts across mixed materials thanks to variable pitch serrated teeth
- • Best for: DIYers, electricians and installers needing clean holes for lights, ducts and fittings
- • Not ideal for: Heavy masonry or thick structural steel cutting where specialised bits are required
Heat-treated carbon steel alloy combined with bi-metal construction and ultra-sharp serrations. Arbor and spring-loaded pilot bit included for quicker hole ejection.
Fast, clean holes – thanks to variable pitch serrated teeth
Variable pitch serrations reduce vibration and maintain cutting momentum across timber, drywall and thin metals, producing cleaner edges. Ultra-sharp teeth slice through fibres and plaster with less splintering than uniform-tooth designs.
Quicker progress on installation tasks and neater holes that require less finishing or sanding.
Quick eject and safer changes – with spring-loaded pilot bit and included arbor
A spring on the pilot bit pushes the cut disc out immediately after the hole is complete, while the included arbor secures the pilot and saw to the drill chuck. Pilot bit stability keeps the saw tracking true during starts.
Faster blade changes and reduced risk of the saw binding, cutting down wasted time on site or in the workshop.
Built for repeat use – with heat-treated carbon steel alloy and bi-metal construction
Heat treatment increases hardness and wear resistance while the bi-metal composition balances toughness with edge retention, allowing repeated cutting cycles without rapid bluntness. Manufacturing prioritises durability over cost-cutting.
Suitable for regular DIY and trade tasks, offering a longer service life compared with lower-grade hole saws.
