Snail Tools HSS M2 Spiral Flute Machine Tap (M3 x 0.5 Coarse Pitch)

M3x0.5 Standard Pitch Tap for Clean Threading in Small, Blind Holes in Steel, Iron, and Non-Ferrous Metals in Canada.

The Snail Tools HSS M2 Spiral Flute Machine Tap is a specialized, fine-diameter tool designed for cutting the standard M3 internal threads in blind (bottoming) holes. The spiral flute geometry is critically important for this small size, as it efficiently coils chips and draws them upward and out of the hole. This action is crucial in preventing chip accumulation and dramatically reduces the risk of tap breakage (a common concern with small taps), ensuring reliable thread cutting in demanding blind-hole applications. Constructed from durable HSS M2 (High-Speed Steel), this tap offers an excellent balance of toughness and wear resistance for continuous use in production environments, suitable for materials like carbon steel, alloy steel, cast iron, and general-purpose non-ferrous metals. This M3 coarse pitch 0.5 mm tap is the industry standard for general small-diameter fastening.

Key Features & Blind Hole Performance

• Thread Specification: M3 x 0.5 Coarse Pitch – The metric standard (coarse) pitch for M3 threads, widely used for general-purpose fastening applications in electronics and small assemblies.

• Flute Geometry: Spiral Flute – Optimized for superior chip evacuation in blind holes, highly essential for small taps to prevent breakage and ensure high thread quality.

• Material: HSS M2 (High-Speed Steel) – A robust Molybdenum-grade steel offering superior hot hardness and toughness for continuous machine tapping operations.

• Application: Ideal for use in CNC machining centers and precision tapping equipment for reliable, high-volume thread cutting where small blind holes are prevalent.
