Totem – HSS Tap Set M4 | High-Speed Steel Metric Threading Tool for M4 x 0.7 mm Threads (3-Piece Set)

The Totem HSS Tap Set M4 is a precision-engineered threading toolset designed to create or repair M4 x 0.7 mm metric internal threads in a variety of materials including steel, aluminum, brass, and plastic. Manufactured by Totem, a globally respected brand in cutting and threading tools, this 3-piece tap set ensures smooth, accurate, and durable threads for industrial, automotive, electronics, and DIY applications.

This set includes three distinct taps—Taper, Intermediate, and Bottoming—making it ideal for threading both through holes and blind holes with full control and finish quality.

What Is an M4 Tap Set?

An M4 tap set is designed for cutting internal threads that match an M4 (4 mm diameter) metric bolt or screw with a 0.7 mm pitch. The Totem M4 tap set includes:

Taper Tap (First Tap) – Used to initiate the threading process, with a gradual cutting edge to reduce force and improve alignment.
Intermediate Tap (Second Tap) – Progressively deepens the thread profile started by the taper tap.
Bottoming Tap (Third Tap) – Completes the thread down to the bottom of the hole, ideal for blind holes (not drilled all the way through).

Using the full set ensures clean, accurate, and long-lasting threads with reduced risk of tool breakage or thread damage.

Material: High-Speed Steel (HSS)

This tap set is made from industrial-grade HSS (High-Speed Steel), known for its:

Superior wear resistance
High heat tolerance
Long tool life under repeated use
Capability to maintain cutting edge sharpness

HSS construction makes the Totem M4 tap set ideal for tapping into harder metals, unlike carbon steel taps which may dull or chip faster.
