Maykestag Speedtap Universal HSS-E Co8 M8 Rolling Tap DIN 2174 6HX TiCN

Maykestag Speedtap Universal HSS-E Co8 M8 Rolling Tap TiCN

Professional M8 x 1.25 Speedtap Universal rolling tap manufactured from HSS-E Co8 and finished with a wear-resistant TiCN coating. Designed to form metric ISO threads without producing cutting chips, with lubrication grooves, DIN 2174 geometry, 6HX tolerance and Form C chamfer for reliable machine thread forming.

The Maykestag Code 4669 Speedtap Universal is a high-performance machine rolling tap for forming metric ISO threads to DIN 13. Unlike a conventional cutting tap, the rolling tap creates the thread by controlled displacement of the workpiece material rather than removing material as chips. This chipless process is particularly useful in suitable ductile materials where clean, repeatable internal thread production is required. The Code 4669 series is manufactured from cobalt-alloyed HSS-E Co8 and protected by a TiCN coating for demanding professional production use.

What is a rolling tap? A rolling tap, also known as a thread-forming or fluteless tap, creates an internal thread by plastically forming and displacing the material instead of cutting it away. Because no cutting chips are produced, there is no swarf that needs to be evacuated from the thread. Correct pre-hole diameter and effective lubrication are especially important because the workpiece material must have sufficient space to flow into the final thread profile during the forming process. Product highlights

• M8 x 1.25 metric thread: Designed specifically for forming an M8 metric ISO thread with a 1.25mm pitch.
• Speedtap Universal: Maykestag's universal high-performance thread-forming design for professional machine threading applications.
• Chipless thread forming: Forms the internal thread through material displacement rather than conventional chip-producing cutting.
• HSS-E Co8 construction: Cobalt-alloyed high-speed steel provides excellent toughness, hot hardness and wear resistance for demanding thread-forming operations.
• TiCN coating: Titanium carbonitride provides a hard, wear-resistant surface suited to repetitive professional machining.
• Lubrication grooves: Designed to assist lubricant distribution along the working area during thread forming.
• DIN 2174: Manufactured according to the dimensional standard specified by Maykestag for this rolling-tap series.
• 6HX tolerance: Precision thread-forming tolerance specified for the Code 4669 Speedtap Universal range.
• Form C chamfer: 2–3 pitch chamfer provides the specified forming lead for controlled thread engagement.
• 5 forming lobes: The M8 version is specified with five forming lobes for controlled material displacement during thread production.
• Through and blind holes: The Speedtap Universal geometry is suitable for both through-hole and blind-hole thread-forming applications.

Why Choose Maykestag?

Maykestag develops precision threading tools for professional machining applications where tool geometry, dimensional accuracy, coating technology and repeatable performance are critical. Thread forming places different demands on a tool compared with conventional thread cutting, making the correct combination of tool material, forming geometry, coating and lubrication particularly important.

The Code 4669 Speedtap Universal combines HSS-E Co8 tool material, TiCN coating, DIN 2174 geometry and a 6HX thread tolerance in a specialised rolling tap designed for chipless internal thread production. Maintaining the specified pre-hole diameter, accurate alignment and effective lubrication is essential for dependable forming performance and a consistent finished thread.

Designed for Controlled Chipless Thread Forming

The M8 Speedtap forms the thread by progressively displacing material as the Form C lead enters the prepared hole. Because material is formed rather than removed, correct preparation of the pre-hole is critical. Maykestag specifies a 6.8mm pre-hole diameter for this M8 x 1.25 Code 4669 tap. Correct machine alignment, suitable lubrication and appropriate forming speed help control torque, protect the tool and produce a consistent thread profile.
