Alpha Step Drill Bits, Impact Power Bits & Cutting Fluid

Alpha is a New Zealand-based cutting tool brand with a strong following in the Australian trade and industrial market, producing a focused range of drill bits, power bits, combination drill-and-tap tools, and cutting fluids that are engineered for performance in professional workshop, construction, and maintenance applications.

Alpha’s reputation has been built on practical innovation — most notably the ONSITE Plus Impact Step Tip drill bit, a step-tip geometry drill designed specifically to resist the walking and wandering that plagues standard twist drills when drilling into hard, sloped, or painted steel surfaces without a centre punch.

This is the kind of problem that costs tradespeople time every day on construction sites and in fabrication shops, and Alpha’s step tip design addresses it directly by providing a self-starting cutting geometry that bites immediately on contact without slipping.

Beyond the step tip range, Alpha produces a comprehensive selection of power bits and impact bits in Phillips, Pozidrive, slotted, square, and hex drive configurations, covering the full spectrum of fastening requirements in both impact drivers and standard drill-driver combinations.

The Combination Drill & Tap tool is a particular standout — a two-in-one cutting tool that drills a clearance hole and cuts the mating thread in a single operation, eliminating the separate tap-and-die step that normally requires a second tool and second setup. Available in both metric and imperial thread sizes.

Alpha’s Liquid Gold cutting fluid is a premium multi-metal cutting oil formulated for drilling, tapping, reaming, and thread-cutting operations on steel, stainless steel, aluminium, and other metals where heat and friction at the cutting edge are the primary causes of premature tool wear and poor finish quality.

Alpha ONSITE Plus Drill Bits & Combination Drill & Tap

Alpha’s drill bit range is centred on its signature ONSITE Plus Impact Step Tip geometry and the Combination Drill & Tap — two tools that solve real productivity problems for trade professionals. Order online at AIMS Industrial.

• Alpha ONSITE Plus Impact Step Tip Drill Bit: Alpha’s flagship drill bit features a patented step tip geometry that allows the bit to start cutting immediately on contact with the workpiece surface without walking or centre-punching — a critical advantage on construction sites and in fabrication shops where steel components are often drilled without a drill press or pillar guide.
• The impact-rated shank is compatible with impact driver chucks and handles the higher torque and hammering action of impact drivers without shank damage. Available in a range of diameters for drilling clearance holes and pilot holes in structural steel, plate, angle, RHS, SHS, and pipe. The step tip geometry also reduces burring on breakthrough, reducing deburring time on production drilling operations.
• Alpha Combination Drill & Tap — Metric: A two-in-one tool that drills a clearance hole and cuts a metric thread in a single operation. The combination drill-and-tap eliminates the need to swap between a drill bit and a separate tap for every tapped hole, reducing cycle time significantly on production tapping operations and in maintenance situations where large numbers of threaded holes must be created quickly. The metric range covers the most common M-series thread sizes used in Australian industrial fastening applications. Suitable for use in mild steel, aluminium, and engineering plastics.
• Alpha Combination Drill & Tap — Imperial: The imperial version of the Combination Drill & Tap covers UNC and UNF thread sizes commonly used on American-manufactured plant and equipment, mining machinery, and older industrial installations that use imperial threaded fasteners. An essential tool for maintenance teams working across both metric and imperial fastener standards, allowing tapped-hole creation in imperial sizes without maintaining a separate imperial tap set.

Alpha Power Bits, Impact Bits & Cutting Fluid

Alpha’s power bit and cutting fluid range gives trade professionals the accessories needed for high-productivity fastening and metal cutting operations. All available to order at AIMS Industrial.

• Alpha Phillips Impact Bit 5/16" Drive: A Phillips head impact bit in 5/16" hex shank format for impact drivers. Impact-rated bits are manufactured from a tougher, more shock-resistant steel alloy than standard power bits, and are designed to absorb the hammering action of impact drivers without the tip fracture or cam-out that occurs when standard bits are used in high-torque impact applications. The 5/16" hex shank is the standard for larger impact drivers used in structural fastening, decking, and heavy-duty assembly. Available in PH1, PH2, and PH3 drive sizes.
• Alpha Hex Ball End Power Bit — Handipack: A ball-end hex (Allen) power bit for driving socket head cap screws and hex socket fasteners at angles up to 25 degrees off-axis — a significant advantage in confined spaces where the driver cannot be held perfectly in line with the fastener axis. The ball end engages the hex socket even at an angle, preventing drive slippage and cam-out that occurs when a standard hex bit is used at an angle. Packed in a handipack retail-friendly format for easy storage and identification in toolboxes.
• Alpha PZ2 x 50mm Pozidrive Power Bit — Handipack 10/Pack: A 10-pack of PZ2 x 50mm Pozidrive power bits in handipack format for drill-drivers and impact drivers. Pozidrive bits have a second set of ribs between the main drive ribs that seat more firmly in Pozidrive screws than a Phillips bit, reducing cam-out on high-torque fastening operations. PZ2 is the most widely used Pozidrive size in Australian construction and general fabrication for decking screws, sheet metal screws, and general assembly fasteners. The 10-pack format provides economical bulk supply for production fastening.
• Alpha Liquid Gold Cutting Fluid 250ml: A premium multi-metal cutting and tapping fluid formulated to extend drill bit and tap life, improve surface finish, and reduce heat generation during drilling, tapping, reaming, and thread-cutting operations on steel, stainless steel, aluminium, copper, and brass. Cutting fluid reduces friction at the cutting edge, carries heat away from the tool tip, and flushes swarf out of the cutting zone — the three most important factors in extending tool life and maintaining cut quality. The 250ml bottle size suits workshop and on-site use where a larger container is not practical.
