The Alpha/Sterling PSM25PBBX is a combo pack containing three tools: an Alpha Black Series 25 piece metric drill set, a Sterling 20oz Striker hammer, and a Sterling 5 metre tape measure. The drill set in the PSM25PBBX runs 1.0mm to 13.0mm in 0.5mm increments, which is precisely what produces 25 bits. The three tools arrive together at 2.747kg packaged.
Three separate purchases generate three deliveries and three invoice lines requiring reconciliation. A drill set terminating at 10mm compels the electrician to reach for a step bit whenever a gland demands a larger aperture. The PSM25PBBX covers 1.0mm to 13.0mm in 0.5mm increments, so the intermediate half-millimetre diameters remain available where a 13 piece set omits them entirely.
Black Series drills are specified for ferrous metal, which is switchboard and enclosure territory rather than timber. The Tuffbox case carries rubber grips and a locking catch, surviving vehicle transportation intact. Alpha includes a feeds and speeds chart, resolving the perennial uncertainty about appropriate rotational speed for a 10mm bit in steel.
The PSM25PBBX drills are jobber bits specified for ferrous metal, not masonry bits, so concrete and brick require a separate masonry bit. The pack contains three tools only: no drill, no driver, and no charger are included. Alpha rates the Black Series for hard ferrous materials, and running them at the wrong speed is what burns the cutting edge, which is why the feeds and speeds chart is in the box.
(PSM25PBBX)
The PSM25PBBX contains three tools: an Alpha Black Series 25 piece metric drill set in a Tuffbox case, a Sterling 20oz Striker hammer, and a Sterling 5 metre tape measure. The whole pack weighs 2.747kg packaged.
The set runs 1.0mm to 13.0mm in 0.5mm increments. That progression produces exactly 25 sizes, which is where the 25 piece count originates. A 13 piece set covers the same span in 1.0mm steps and omits every half-millimetre size in between.
Alpha specifies the Black Series for hard ferrous materials, including steel. The set is supplied with a feeds and speeds chart matching bit diameter to the appropriate drilling speed, because running a bit too fast in steel is what destroys the cutting edge.
These are jobber drills specified for ferrous metal, not masonry bits. Concrete, brick, and render need a masonry bit with a carbide tip, ideally driven by a hammer drill or an SDS machine. Sparky Direct stocks Alpha SDS Plus masonry bits separately for that work.
The Sterling 20oz Striker has a drop forged steel head and a cushioned grip on the handle. Drop forging compacts the grain of the steel rather than pouring it into a mould, which is why forged heads are the trade standard for striking tools.
The pack contains drill bits, not a drill. There is no power tool, battery, or charger in the PSM25PBBX. The three items supplied are the drill bit set, the hammer, and the tape measure.
The PSM25PBBX 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 drilling is not a warranty matter.
The Alpha/Sterling PSM25PBBX 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.
