Star-M Japanese Auger Drill Bits — Standard, Extended Length & Hardwood Series
Star-M is a Japanese precision woodworking tool manufacturer producing high-quality auger drill bits for timber boring in construction, cabinet making, electrical installation, plumbing rough-in, and structural timber applications.
Japanese auger drill bits are recognised by tradespeople working in hardwood as the superior alternative to locally-produced and mass-market European auger bits — the Japanese manufacturing process and tool steel quality produces a screw-point tip and cutting spur geometry that penetrates Australian hardwoods including Ironbark, Jarrah, Blackbutt, and Spotted Gum with significantly less splitting, splintering, and blow-out than bits produced to lower specification tolerances.
Star-M offers multiple series to match specific timber boring requirements: the 8M and 6 series for general-purpose boring in softwood and hardwood structural timber, the 4S series for short-body boring in confined access, the 8L series specifically rated for Australian hardwood boring with a modified point and spur geometry for these notoriously hard and fibrous timbers, and the extended-length 4L series for through-boring in deep timber sections and structural beams where standard-length bits cannot reach the far face.
All Star-M auger bits are manufactured to tight dimensional tolerances for on-size holes without reaming, and the flute geometry provides efficient chip evacuation from deep holes to prevent bit binding in long-bore applications.

Star-M Auger Drill Bits — 8M, 6 & 4S Series
The 8M, 6, and 4S series cover general-purpose timber boring in softwood and standard hardwood applications. Select the series based on timber species, hole depth, and space constraints.
- Star-M Auger Drill Bit — 8M Series: The Star-M 8M series is a general-purpose auger drill bit for boring clean-sided holes in softwood framing timber, pine, and medium-hardness hardwoods for electrical cable, plumbing, and fastener access holes. The 8M series has a standard-length flute for accessible boring locations and produces clean entry and exit holes with minimal tear-out in the softwood and medium-hardwood range. Available in multiple diameter steps from small cable-pass sizes through to large bolt-bore diameters.
- Star-M Auger Drill Bit — 6 Series: The Star-M 6 series auger provides a modified cutting geometry from the 8M for applications where the 6 series profile produces better results in specific timber species or moisture conditions. The 6 series is selected by experienced timber tradespeople who have identified a preference for its chip evacuation and spur entry characteristics in their primary working timber type.
- Star-M Auger Drill Bit — 4S Series: The 4S series is a short-body auger drill bit for boring in confined spaces where a standard-length auger cannot be started perpendicular to the timber face due to structural clearance constraints. Short-body augers are commonly required for boring through wall plates from below in finished ceiling spaces, for notching in completed wall cavities, and for retrofitting cable and pipe routes in existing structures where full-length bit access is obstructed.
Star-M 8L Series Hardwood Auger Bits & Extended Length 4L Series
The 8L hardwood series and extended-length 4L series address the most demanding timber boring requirements. Order the right series for your species and depth — available now at AIMS Industrial.
- Star-M Auger Drill Bit — 8L Series (Hardwood): The Star-M 8L series is specifically optimised for boring in Australian hardwood species including Ironbark, Merbau, Tallowwood, Blackbutt, and Spotted Gum that are notoriously difficult for standard auger bits. The 8L point and spur geometry is designed to cope with the high density, interlocked grain structure, and silica content of Australian hardwoods — entering cleanly without wandering on the grain surface and cutting through without the bit seizing in the high-friction bore that causes standard bits to bind and burn in dense hardwood. Electricians and carpenters working regularly in Australian hardwood construction use the 8L as their primary species-rated bit for long-term reliable performance.
- Star-M Hardwood Auger Drill Bit Bundle 12mm & 13mm — 8L Series: A bundle pack of 12mm and 13mm Star-M 8L series hardwood auger bits — the two most commonly used cable-pass diameters for electrical installation in hardwood-framed residential and commercial construction. Buying the bundle provides both sizes at a combined price, giving electricians immediate access to the two most frequently needed bore sizes for standard 3-core TPS and conduit cable-pass holes in hardwood framing without separate orders.
- Star-M Auger Drill Bit Extended Length — 4L Series: The extended-length 4L series provides significantly greater boring depth than the standard 8M and 8L series for boring through deep timber sections including glulam beams, LVL structural members, and double-stud wall framing where standard-length bits exit the shank before clearing the far face. Extended-length augers are essential for structural bolt installation, through-floor plumbing and electrical runs, and cable routing through thick engineered timber elements in contemporary timber-frame construction.
- Star-M Extended Length Auger Bundle — 4L Series: A bundle pack of Star-M 4L extended-length auger bits covering a range of diameters for structural timber boring applications. The bundle provides the range of bore sizes required for structural bolt installation (most commonly 12mm, 16mm, and 20mm) and for running multiple cable and pipe sizes through the same timber member without requiring separate orders for each diameter.
- Star-M Auger Drill Bit 305mm x 12mm 8M Series — Pack of 50: A production pack of 50, available for special order, Star-M 305mm x 12mm 8M series auger bits for high-volume cable-pass boring in electrical installation projects. The 12mm diameter is the standard cable-pass size for 2.5mm² TPS flat cable in residential wiring, and the pack-of-50 format suits large residential project teams and electrical contractors running multi-crew sites.
