SKU CH-K672-4NK5H

A straight-flute hand tap cuts M2×0.4 metric threads in a 44.45 mm overall length with 11.11 mm thread length, three flutes and a D3 limit for 6H class fit

  • Metric M2x0.4 thread for fine-pitch fastening
  • Bottoming chamfer cuts full threads to hole bottom
  • 3-flute high-speed steel resists wear in hand tapping
  • 45 mm overall length fits standard tap handles
  • 60 mm drill size ensures 75 % thread engagement

M2x0.4 Metric Thread Tap

The Cleveland C54075 is a straight-flute hand tap for cutting M2x0.4 metric threads in through or blind holes. It suits maintenance technicians and hobbyists who need to create internal threads by hand in steel or non-ferrous metals. The D3 thread limit produces a 6H class of fit for standard assemblies. This tool is not for buyers who need machine tapping or coated performance.

Bright High-Speed Steel Construction

The uncoated bright finish on high-speed steel keeps the cutting edges sharp for general-purpose hand threading. Three flutes provide chip clearance while the bottoming chamfer allows threads close to the bottom of a blind hole. No surface treatment means the tap requires cutting fluid and more frequent sharpening than coated alternatives. Buyers who want longer tool life without lubricant should look elsewhere.

11.11 mm Thread Length

The 11.11 mm thread length determines how deep a full-form thread can be cut in a single pass. Combined with the 44.45 mm overall length, it sets the reach for shallow holes in thin workpieces. The 1.60 mm drill size for 75 percent thread engagement must be matched exactly for correct fit. Shops needing deeper threads or different engagement percentages cannot use this specification.

Questions about this item

Will the M2x0.4 tap need replacement once the HSS cutting edges dull from repeated threading?

The high-speed steel construction resists wear during hand-tapping operations, and the tool can be resharpened multiple times before replacement becomes necessary.

What limits continuous use of the 11.11 mm thread-length section before chip packing occurs?

The straight-flute design and 44.45 mm overall length require frequent reversal to clear chips, so sustained threading is limited by manual chip evacuation rather than a thermal threshold.

Does the bright uncoated finish generate noticeable heat during all-day tapping of 1.60 mm drill holes?

Hand-driven cutting speeds keep temperatures low, and the uncoated HSS surface dissipates heat adequately for intermittent use without excessive warmth buildup.
