Precision threading starts with Wiseman's Metric Fine HSS Hand Tap Set, engineered for clean internal threads in M24x1.25 with ISO 529 specification. This uncoated, ground high-speed steel tapping set delivers reliable cutting action, excellent accuracy, and long service life for your everyday metalworking tasks.

What makes this tapping set stand out:

• ISO 529 compliant geometry ensures standard thread form and cross-compatibility with M24x1.25 nuts and components, so you can trust consistent fit every time.
• High-speed steel, ground and uncoated provides sharp cutting edges, precise thread profiles, and dependable wear resistance across a range of metals.
• Right-hand thread is the most common configuration for most workshops, guaranteeing straightforward use in general fabrication, repair, and assembly projects.
• Three leads—taper, plug (second), and bottom—guide the tapping process from the initial entry through depth, reducing tool stress and minimizing the chance of broken taps.
• Metric fine pitch benefits give you tighter, higher-precision threads for assemblies where precision matters, from machinery housings to automotive components.
• Versatile, general-purpose tool ideal for creating internal threads in steel and aluminum, with proper cutting fluid and careful alignment for best results.

Practical use tips for best outcomes: start with a clean, pre-drilled pilot hole sized for the M24x1.25 tap, maintain steady, straight alignment, apply a light cutting fluid, and rotate only in the cutting direction. Retrace occasionally to clear chips and back off gently if you feel binding. After tapping, remove the plug gently and run a die or thread gauge to verify the fit.

Designed for professionals and serious DIYers alike, this Wiseman tap set delivers reliable performance when you need precise internal threads without guesswork. It’s the trusted choice for consistent results—whether you’re rebuilding a fixture, fabricating a new part, or performing routine repairs in metalworking projects.
