Blind machine tap DIN 376 C HSS-E TiN – Koronet

The DIN 376 C HSS-E TiN machine tap is a professional tool designed for precise internal threading in structural steels, low-alloy steels and medium-strength materials. Made of durable HSS-E high-speed cobalt steel and coated with a classic TiN coating, it ensures stable operation, increased wear resistance and good performance in series and unit production processes.

HSS-E steel – increased heat resistance and stability

The tool is made of high-speed steel with the addition of cobalt (HSS-E), which is characterized by:

• high resistance to torsional loads,

• increased hardness at temperature,

• better abrasion resistance compared to classic HSS steel.

This ensures that the tap maintains stable performance even in high-strength materials and during longer machining cycles.

TiN coating – durable, universal, proven

The TiN (titanium nitride) coating offers:
– increased abrasion resistance,
– reduction of friction in the cutting zone,
– more efficient heat dissipation,
– improvement of the quality of the thread surface.

It is a proven and reliable solution for a wide range of standard applications in structural steels and medium-strength materials.

Spiral geometry – ideal for blind holes and ductile materials

The screw groove directs the chip backwards (upwards), which allows you to:

• safe threading of blind holes,

• stable operation in malleable materials,

• reduction of the risk of chip jamming,

• Better thread profile forming.

Screw groove is the geometry preferred in series production, especially for machining low-alloy and structural steels.

DIN 376 standard – slimmer handle, greater working access

The tap compliant with DIN 376 is characterized by:

• slimmer build,

• extended grip,

• easier access to deeper openings.

It is an ideal solution for CNC machine tools and conventional machines, where the convenience of the tool and precision of movement are important.

Version C – Medium Phase (2-3 Rolls)

Cut type C is the most versatile choice for threading blind holes and for materials where safe chip evacuation is important.
It makes it easier to start threading and ensures stable profile forming.

The DIN 376 C HSS-E TiN tap is ideal for machining:
• structural steels,
• unalloyed and low-alloy steels,
• medium-strength materials,
• metals with ductile behaviour and prone to build-up.

The tool is suitable for work on CNC machines and conventional tapping machines, where repeatability, smooth operation and tool life are important.
