Center-hole bar solutions
for Taps

In the world of industry and machining, precision and efficiency are essential to ensure the quality of finished products. This is where taps, used to create threads, play a crucial role. At Forécreu, we’re committed to providing you with customized solutions for tap manufacturing, using center-hole bars made from high-speed steels (HSS). Find out how our products meet the industry’s needs in terms of size, performance and durability.

The importance of taps in industry

Taps are essential tools in industry, used to create internal threads in metal parts, plastics and other materials. They are essential for assembling components, for fastening and for creating complex parts. The quality of the thread created depends largely on the precision and durability of the tap used.

The benefits of high-speed steels for tap manufacturing

High-Speed Steel (HSS) is the material of choice for the manufacture of taps. Here’s why HSS taps are widely preferred in the industry

Exceptional hardness

HSS taps are tempered to achieve outstanding hardness. This means they can withstand high loads, drill efficiently and retain their sharpness over time. The hardness of HSS taps guarantees increased durability.

Heat resistance

During the tapping process, heat is generated by friction. HSS taps are designed to withstand these high temperatures, ensuring that the tool remains efficient and does not warp during use.

Abrasion resistance

HSS taps are capable of withstanding wear and abrasion, enabling strict dimensional tolerances and consistent thread quality to be maintained.

High-speed performance

HSS taps are ideal for high-speed applications, enabling faster and more efficient work.

The benefit of the center hole

The center hole in a tap is more than just a feature; it’s a key element in optimizing the tool’s performance. Here’s why it is so important:

Precise guidance
The center hole guides the tap precisely into the material, ensuring controlled penetration and precise threading. This reduces the risk of deviation or misalignment.

Chip evacuation
Chips are generated during the tapping process. The center hole ensures efficient chip evacuation, preventing tool clogging and guaranteeing clean threads.

Reduced torque
The center hole reduces the torque required for tapping, making it easier and less tiring for the operator.

Meeting industry standards in terms of dimensions
