The M4 (M4 x 0.7) is a critical fastener size used extensively in automotive sensors, electrical enclosures, and light machinery. Our DIN 352 M4 Hand Tap Set is engineered to produce high-precision internal threads in manual operations.
By utilizing the traditional 3-piece sequence (Taper, Plug, and Bottoming), this set allows users to form threads gradually. This is especially important for the M4 size, where the tool's core diameter is relatively thin; distributing the cutting load across three taps significantly reduces the risk of torque-induced breakage in expensive workpieces.
We offer this set in two high-speed steel grades to suit your market’s specific needs:
• HSS-M2 (Professional Grade): Best for tough alloy steels, stainless steel, and high-volume industrial use. Features superior "Red Hardness" and wear resistance.
• HSS-4341 (Standard Grade): A cost-effective solution for general repairs, mild steel, aluminum, and brass applications.

Precision Component Manufacturing: Ideal for creating reliable threads in aluminum heatsinks, small engine casings, and custom brackets.
MRO & Field Maintenance: A must-have for maintenance engineers repairing stripped threads in control panels and mechanical assemblies.
Blind Hole Capability: The No.3 Bottoming tap in this set allows for full thread depth even in shallow blind holes, ensuring maximum bolt engagement.
Anti-Breakage Strategy: For small sizes like M4, manual verticality is hard to maintain. The long lead on our No.1 Taper tap ensures the tool "finds" the center easily, preventing the "tilting" that usually snaps smaller taps.
