RUKO SCE-DIN22568-HSS-60°-9/16 Hand Tap Set M3-M12, 21 Pieces, HSS-G, DIN 352, Metric Threads, Bright Finish, Metal Case

Cutting internal threads by hand often means juggling multiple tap sizes, guessing at tolerances, and dealing with dull edges that tear instead of cut. This RUKO hand tap set eliminates that frustration with a complete range of metric taps in one organized metal case, each ground from high-speed steel for clean, precise threads in a wide range of materials.

Who is it for

This set is built for machinists, maintenance technicians, and serious DIYers who regularly tap holes in steel, cast iron, non-ferrous metals, or plastics. It covers the most common metric sizes from M3 to M12, making it a go-to kit for repair jobs, prototyping, and small-batch production.

Main features

• Complete metric range: 7 thread sizes — M3, M4, M5, M6, M8, M10, M12 — each with 3 taps (taper, second, bottoming) for through and blind holes.
• Precision ground HSS-G: High-speed steel with ground flutes delivers clean cuts, long life, and consistent thread quality.
• DIN 352 standard: Taps conform to DIN 352 for reliable interchangeability and thread geometry.
• ISO 2 (6H) tolerance: Produces threads to the common 6H fit, suitable for standard fasteners.
• Right-hand cutting: Standard clockwise cutting direction for conventional tapping.
• Square shank (DIN 10): Fits all standard tap wrenches and holders.
• Bright finish: Corrosion-resistant surface treatment for durability and smooth chip flow.
• Robust metal case: Keeps all 21 taps organized and protected, with clear size labeling.

Tips

Always use a suitable cutting fluid when tapping metals to improve finish and extend tap life. For blind holes, start with the taper tap, then follow with the second and bottoming taps to achieve full thread depth. Store taps in the provided case to prevent edge damage.
