About this item

• 10-IN-1 METAL COUNTERSINK SYSTEM: 1main body, 4 drii bits (HSS), 4 reversible countersink heads (HSS) (8 sizes) + 1 countersink bit (HSS), 1 depth stop set, 1 chamfer tool,1phillips bit. 9 precision hole options, breakthrough for ?hardened steel/stainless alloys, outperforming wood-only competitors.
• ¡¾0.5MM DEPTH CONTROL: Hex Key-Accurated Stop Prevents Over-Drilling & Burrs? Integrated depth-stop with included hex key achieves ??¡¾0.5mm industrial-grade precision; free-spinning plastic collar protects surfaces, ensuring ?flush screw heads? in one operation.
• 9-SIZE QUICK-CHANGE EFFICIENCY: 50% Faster Than Standard Bits? Reversible heads flip for instant size switching (8-10*2.8mm/8-10*3mm/8-10*3.2mm/8-10*3.5mm/14mm*90¡Æ); spiral design? clears wood/metal chips 3x faster, quickly switch to the phillips bit and tighten the screwseliminating bit changes and boosting productivity.
• CHAMFER TOOL INTEGRATION: 45¡Æ Deburring Edges in One Pass? Vertical pilot syncs with chamfer tool for ?45¡Æ edge-smoothing; removes sharp burrs on metal/wood instantly, ?saving 30% polishing time? vs. standalone tools
• ORTABILITY CASE?: 250g lightweight case organizes all bits + tools; backed by ?lifetime breakage replacement? + 90-day guarantee.
