Learn more by watching our Alpha RDD-SET8 | Destructor Reciprocating Blade Set | 8 Set video.
The Alpha RDD-SET8 is an eight piece reciprocating blade set from the Alpha Destructor demolition range, supplied with a pouch. The RDD-SET8 contains four blade types in pairs: 230mm wood and nails, 150mm wood and nails, 150mm metal and timber, and 150mm medium metal. Every blade is 8 percent cobalt bi-metal, with tooth pitches spanning 5 to 14 TPI.
Demolition and strip-out work rarely remains within a single material. A blade selected for timber encounters a nail plate or an abandoned conduit run, and surrenders its teeth within a metre. The RDD-SET8 accommodates that transition with four blade types supplied in pairs. Tooth pitch spans 5 to 14 TPI, so the appropriate tooth geometry sits in the pouch rather than remaining in the van.
Carrying a complete set instead of individual blades means demolition never halts while somebody drives across town for a replacement. 8 percent cobalt bi-metal is the alloy Alpha specifies across the Destructor range. Ice-hardened teeth with ProShield accommodate the temperature a reciprocating saw generates in metal, and the supplied pouch retains eight blades flat and identifiable rather than loose in a bag.
The RDD-SET8 supplies blades and a pouch only, with no reciprocating saw included. The set is rated for timber and metal duty, not for masonry, tile, or concrete. Reciprocating blades are uninsulated, so isolate and prove dead before cutting into any conduit, cable, or enclosure that may be live.
(RDD-SET8)
The RDD-SET8 supplies eight blades in four types, two of each: 230mm wood and nails, 150mm wood and nails, 150mm metal and timber, and 150mm medium metal. All eight are 8 percent cobalt bi-metal. A pouch is included for storage.
Match tooth pitch to the material. Coarse pitch suits timber, because a bigger gullet clears the chip and stops the blade packing. Fine pitch suits metal, because more teeth stay in contact with thin section and stop the blade snagging. The RDD-SET8 spans 5 to 14 TPI across the four types.
Destructor blades use the standard reciprocating shank, so they suit most reciprocating saws across the common brands. Check the shank on your saw against the blade before ordering if the saw is older or uses a proprietary fitting.
Bi-metal means two steels welded together: a flexible spring steel body and a harder tooth edge. The 8 percent cobalt sits in the tooth edge, which raises the temperature the tooth tolerates before losing hardness. The body still flexes rather than snapping under a plunge cut.
Alpha rates the wood and nails blade for softwood, hardwood, wood with nails, and plastic. The metal and timber blade covers wood with nails, metal, stainless steel, non-ferrous metal, aluminium, cast iron, and pipes. The medium metal blade carries the finest pitch in the set for metal work.
Sparky Direct stocks Destructor singles alongside the set, including the Alpha RDDM1508-25 metal and timber blade at 150mm and the RDDM2308-25 at 230mm. Buying the set first identifies which type the work consumes, then singles or bulk packs restock that type.
The RDD-SET8 carries a 1 year warranty for domestic use and a 1 year warranty for commercial use, both running from the invoice date. The warranty method is return to Sparky Direct. Consumable wear from normal cutting is not a warranty matter.
The Alpha RDD-SET8 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.
