Key features

  • •All-in-One SAE & Metric Threading Coverage: Complete 81-piece tap and die set covering SAE #4–1/2" and Metric M3–M12, including both coarse and fine threads. Designed for cutting new threads, repairing damaged fasteners, or rethreading stripped holes—ideal for everyday shop and maintenance work
  • •Industrial-Grade GCr15 Bearing Steel (60 HRC): Crafted from heat-treated GCr15 bearing steel with Rockwell hardness up to 60 HRC, delivering excellent wear resistance and torque strength. Maintains cutting accuracy under load without deformation, even during repeated rethreading tasks
  • •Precision CNC-Machined Cutting Teeth: CNC-ground taps and dies produce clean, accurate internal and external threads on steel, aluminum, brass, copper, and cast iron. Optimized tooth geometry reduces friction and cross-threading for smoother, more controlled threading
  • •Dual Thread Pitch Gauges & Spiral Extractors: Includes both SAE and metric thread pitch gauges for fast, accurate thread identification. Spiral flute bolt extractors (EZ-Out style) help remove broken bolts and studs without damaging surrounding threads—saving time on repairs
  • •Adjustable Tap & Die Wrenches for Control:Adjustable tap and die wrenches provide secure locking, precise alignment, and steady pressure across multiple sizes. Supports straight, consistent threading—especially helpful for hand-guided repairs and fine adjustments
  • •Organized, Ready-to-Use Tool Kit: Includes 68 taps and dies, long-handle tap wrench, T-handle tap wrench, adjustable die wrench, screwdriver, center punch, dual pitch gauges, and 5 extractors—neatly stored in a rugged blow-molded case for easy transport and storage
