Description
- Large-Size Metric Thread Coverage: 52-piece metric tap and die set covering M6×0.75 to M24×3.0 in coarse and fine threads. Designed for cutting new threads, repairing stripped holes, and restoring large bolts in engines and machinery
- Industrial-Grade GCr15 Bearing Steel (60 HRC): Heat-treated GCr15 steel delivers high wear resistance and torque strength. Maintains cutting accuracy under load without deformation, even during repeated rethreading tasks
- Precision CNC-Machined Cutting Teeth: CNC-machined taps and dies produce clean, accurate internal and external threads on steel, stainless steel, aluminum, brass, copper, and cast iron while reducing friction and cross-threading
- Metric Thread Pitch Gauge & Spiral Extractors: Includes a metric pitch gauge for fast and accurate thread identification. Spiral flute extractors help remove broken bolts or studs without damaging surrounding threads
- Adjustable Tap & Die Wrenches for Control:Adjustable tap and die wrenches provide secure locking, precise alignment, and steady pressure across multiple sizes. Supports straight starts, stable engagement, and consistent threading under heavy load
- Complete Accessory Kit: Includes 20 taps, 20 dies, a tap wrench, die wrench with adapter, T-handle wrench, adjustable tap wrench, spring-flute extractors (3–18 mm), a flat screwdriver, center punch, and a metric pitch gauge—all neatly stored in a durable blow-molded case
- Built for Heavy Equipment & Industrial Repairs: Designed to restore large stripped threads on trucks, farm equipment, engines, structural hardware, and heavy machinery—trusted by mechanics, technicians, and serious DIY users
