US PUS PRO Industrial 7080 – 10-Pc M35 Cobalt Left-Hand Drill Bit & Screw Extractor Set

Tackle seized and snapped fixings with the US PRO Industrial 7080. Start with the left-hand spiral cobalt drill bits; their reverse rotation often bites and walks the broken fastener loose while you drill a centered pilot. When needed, follow up with the matched cobalt screw extractors to back the remnant out. Made from HSS M35 (5% cobalt) for heat resistance and edge retention on stainless steel, high-tensile and alloy steels. Precision 135° split-point, fully ground flutes (DIN 338) and quality hardness ratings deliver clean, accurate results. Packed in a durable metal case for workshop use.
