        Re-Load | Hi-Flex Bi-Metal Holesaw 16mm | Cobalt High-Speed Steel

        The Re-Load RLHS16 is a 16mm bi-metal holesaw with cobalt high-speed steel teeth, rated for a 32mm cutting depth. The RLHS16 cuts wood, metal, and plastic, and mounts to the Re-Load quick change arbor system for tool-free blade swaps. It is supplied as a single replacement holesaw for the Re-Load 14 to 200mm heavy-duty arbor range.

        Boring a clean 16mm penetration through mixed substrates slows a fit-off whenever the holesaw will not bite or the cutting edge dulls partway through. The RLHS16 carries cobalt high-speed steel teeth that retain their edge across timber, sheet metal, and plastic, so a single holesaw covers the substrates commonly encountered on a job. Its 32mm cutting depth clears standard plate and stud thickness in one continuous pass.

        The RLHS16 seats into the Re-Load quick change arbor, so an electrician can interchange hole sizes within seconds without unthreading a pilot or the arbor itself. The one-touch tool release keeps size changes off the critical path when a run demands 16mm immediately, followed by a larger diameter minutes later. As a replacement blade within the 14 to 200mm Re-Load range, it restocks a holesaw case an electrician already carries between jobs.

        Features

        • Cobalt high-speed steel teeth — cut timber, sheet metal, and plastic without a blade change between materials on the same run.
        • 16mm cut diameter — sized for a common cable, gland, and cordgrip entry hole through plate, stud, and sheet metal.
        • 32mm cutting depth — the RLHS16 clears standard timber plate and single sheet-metal thickness in one pass.
        • Re-Load quick change system — the holesaw mounts and releases from the arbor without tools for fast size changes.
        • One-touch tool release — swap the RLHS16 for another size in seconds without stopping to unthread the arbor.
        • Two-Up hole enlargement — open an existing hole out to 16mm using the Re-Load Two-Up method rather than a fresh pilot.
        • Bi-metal construction — a hardened cobalt edge on a flexible back resists shock in interrupted and off-centre cuts.
        • Recommended speeds supplied — run at 275 rpm in mild steel, 410 rpm in aluminium, and 2400 rpm in wood.
        • Standard holesaw fit — suits all standard holesaw sizes across the Re-Load 14 to 200mm arbor range.
        • Blade-only supply — the RLHS16 ships as a single 16mm saw to restock a kit, so a compatible Re-Load arbor is needed to run it.
        • Green size marking — the 16mm size is colour-coded green for quick identification in a holesaw case.

        Where to use

        • Switchboard and enclosure entries — bore 16mm cable and gland entries into metal and plastic boards during a board build.
        • Stud and plate penetrations — run 16mm holes through timber studs and top plates for cable pulls.
        • Sheet-metal fit-offs — cut clean 16mm openings in trunking, cabinets, and ducting on commercial work.
        • Cordgrip and gland holes — size a 16mm entry for cable glands and cordgrips on a fitting or luminaire.
        • Existing hole enlargement — use the RLHS16 with the Two-Up method to open a smaller entry out to 16mm.
        • Mixed-material renovation work — one saw for timber, plastic, and light metal across a reno without swapping tools.
        • Mobile tool kits — the RLHS16 restocks a Re-Load quick change case carried between jobs.

        The RLHS16 is not rated for masonry, concrete, brick, or tile: its cobalt high-speed steel teeth are cut for wood, metal, and plastic, not stone. It cannot cut past its 32mm depth in a single pass, and it will not run without a compatible Re-Load quick change arbor.

        (RLHS16)

        The RLHS16 fits the Re-Load quick change arbor system. It mounts and releases without tools using the one-touch release and shares the standard holesaw fit used across the Re-Load 14 to 200mm range. It ships as a blade only, so a compatible Re-Load arbor is needed to run it.

        The RLHS16 uses cobalt high-speed steel teeth that cut timber, sheet metal, and plastic. It is not made for masonry, concrete, brick, or tile. Recommended speeds are 275 rpm in mild steel, 140 rpm in stainless, 380 rpm in brass, 410 rpm in aluminium, and 2400 rpm in wood.

        The Re-Load RLHS16 cuts a 16mm diameter hole to a maximum depth of 32mm in a single pass. The 16mm size is colour-coded green for quick identification when a case holds several holesaw sizes together.

        The RLHS16 works with the Re-Load Two-Up system, which opens an existing hole rather than starting a new pilot. This suits widening a smaller entry out to 16mm on the board or through a plate without re-drilling from scratch.

        The RLHS16 is supplied as a single replacement holesaw, not a full arbor kit. It restocks a worn or missing 16mm blade in an existing Re-Load quick change set. The blade carries a 12-month warranty against faulty workmanship and materials from the invoice date.

        The RLHS16 cuts to a maximum depth of 32mm in one pass, so it cannot bore through material thicker than that in a single cut. For sheet metal, plate, studs, and plastic within that depth, the cobalt teeth cut cleanly through mixed substrates.

        The Re-Load RLHS16 is available online from Sparky Direct, with Australia-wide delivery to any state or territory including regional areas. Sparky Direct is an Australian electrical wholesaler established in 2005, supplying more than 500,000 customers with transparent trade pricing.
