Widia Gtd VTSFT-TC5562 Spiral Flute Tap M12x1.50 Bottoming 2 Flutes

SKU CH-WH8T-T8N3K

M12 x 1.50 spiral-flute tap cuts fine metric threads in blind holes with two flutes

  • M12 x 1.50 metric fine thread for precise fastening
  • Spiral flute design clears chips efficiently in blind holes
  • Two-flute geometry balances strength and chip evacuation
  • High-speed steel construction resists wear during repeated use
  • Black oxide finish reduces friction and extends tool life

Widia Gtd Spiral Flute Tap M12x1.50

The Widia Gtd VTSFT-TC5562 is a new spiral flute tap designed for creating internal threads in metalworking applications. It features a metric fine thread size of M12x1.50 with a bottoming chamfer and two flutes for chip evacuation. This high-speed steel tool suits machinists and maintenance technicians producing blind holes.

Suited for blind-hole threading in metric fine sizes

This tap suits workshops cutting M12x1.50 threads to a 6H class of fit using high-speed steel with black oxide finish. It is not for buyers who need a different thread pitch, diameter, or class of fit. It is not for operators requiring a taper or plug chamfer for through-hole work. It is not for users needing more than two flutes for specific chip management.

Critical spec: M12x1.50 thread size

The defining specification is the M12x1.50 metric fine thread combined with a bottoming lead. This determines whether the tool matches the required hole depth and thread standard. Verify the 1.50 mm pitch and bottoming style against your drawing before ordering. The 2-flute geometry and D5 limit support this specific thread form.

Questions about this item

Will the 2-flute M12×1.50 tap need resharpening or replacement after extended threading work?

The high-speed steel body with black-oxide coating resists wear; resharpen when flank wear reaches the D5 limit or chip evacuation slows in deep M12×1.50 holes.

What stops continuous tapping first — chip packing or tool deflection — in a 23.9 mm thread length?

Spiral flutes pull chips upward, so chip packing is relieved; the 85.9 mm overall length keeps deflection low for the 10.50 mm drill size.

Does the black-oxide HSS tap run hotter or draw more spindle power than bright-finish taps in all-day production?

Black oxide reduces friction and heat buildup, so spindle load stays consistent during sustained M12×1.50 threading cycles.
