For Australian auto body repairers, panel beaters, and metal fabricators removing factory spot welds during repair work, the right spot weld bit makes the difference between clean panel separation and damaged work that needs additional repair. AIMS Industrial supplies spot weld drill bits in HSS and carbide-tipped formats.\u003c\/p\u003e\n\n\u003ch3\u003eHow spot weld bits work\u003c\/h3\u003e\n\u003cp\u003eThe bit has a centre pilot (a small drill point) that locates in the centre of the spot weld, surrounded by an annular cutting edge that drills through the top panel without contacting the bottom panel. As the bit penetrates the top panel, the spot weld nugget is severed at the bottom panel surface, allowing the top panel to be lifted off cleanly. The bottom panel surface is preserved for re-welding or refinishing.\u003c\/p\u003e\n\n\u003ch3\u003eThe bit types we stock\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHSS spot weld drill bits\u003c\/strong\u003e — the everyday choice for general spot weld removal in mild steel panels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHSS-E (cobalt) spot weld bits\u003c\/strong\u003e — for harder and high-strength steel panels (HSS, AHSS, and similar)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarbide-tipped spot weld bits\u003c\/strong\u003e — for the toughest panels including modern boron steels and ultra-high-strength materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaceable-pilot spot weld bits\u003c\/strong\u003e — bit body holds replaceable centre pilots, extending tool life\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhere spot weld drill bits earn their place\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuto body repair\u003c\/strong\u003e — removing damaged outer panels for replacement, rocker panel and quarter panel replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial panel repair\u003c\/strong\u003e — replacing damaged panels on machinery, enclosures, and fabricated assemblies\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRestoration work\u003c\/strong\u003e — removing original spot welds during heritage vehicle and equipment restoration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturing rework\u003c\/strong\u003e — removing incorrect or defective spot welds during production\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSizing\u003c\/h3\u003e\n\u003cp\u003eSpot weld drill bits are sized by the cutting diameter — common sizes are 6mm, 8mm, and 10mm, matching typical spot weld nugget diameters. Match the bit size to the spot weld being removed; significantly oversized bits remove unnecessary surrounding material, undersized bits don't fully sever the weld nugget. For modern automotive panels with smaller spot welds, smaller bits (5mm and 6mm) are increasingly common; for heavier industrial spot welds, larger 10mm bits may be needed.\u003c\/p\u003e\n\n\u003ch3\u003eHSS versus carbide — when to spec which\u003c\/h3\u003e\n\u003cp\u003eModern automotive sheet steel has progressively become harder and stronger over the years. Older mild steel panels (typical pre-2000 vehicles) are easily handled by HSS bits. Mid-vintage panels with high-strength steel may demand HSS-E (cobalt) for reasonable bit life. Modern AHSS (advanced high-strength steel) and boron steel panels often require carbide-tipped bits — HSS bits dull within a single weld in these materials. For body shops working on modern vehicles, carbide-tipped bits are the right specification despite the higher cost.\u003c\/p\u003e\n\n\u003ch3\u003eDrilling practice\u003c\/h3\u003e\n\u003cp\u003eRun the drill at moderate speed (typical 800-1500 RPM depending on bit material). Apply firm even pressure — the centre pilot must engage the spot weld centre before the cutting edge starts to bite. Cutting fluid (a small amount of cutting oil) extends bit life; running dry shortens life dramatically. Remove the bit periodically to clear chips. When the cutting edge breaks through the top panel, stop pressing — the spot weld is severed and continued drilling damages the bottom panel.\u003c\/p\u003e\n\n\u003ch3\u003eBrands stocked at AIMS\u003c\/h3\u003e\n\u003cp\u003eSutton Tools, Bordo, and approved cutting tool brands cover the spot weld drill bit range across HSS, HSS-E, and carbide-tipped formats.
