Torpedo Series-3

Spiral Fluted Taps - Torpedo Series

+91-8777212335

Short Description

Blind holes have one rule that trips up a lot of general-purpose taps, whatever chips are cut have nowhere to go except back out the way the tap went in. That's the exact problem the Torpedo Series is built to solve. The helical flutes, ground at a steep angle along the length of the tap, curl the chips upward and carry them out of the hole as the tap cuts, instead of letting them pack down at the bottom. This makes a real difference on stainless steel, aluminium, and other metals that tend to produce long, stringy chips rather than short fragments. Genuine Enterprises manufactures these spiral fluted taps for shops that need dependable blind-hole threading without constantly backing the tap out to clear debris.

  • Material: manufactured from high speed steel, chosen for balanced hardness and toughness in cutting applications.
  • Grades: available in standard HSS and cobalt HSS-E for stainless steel and harder alloys.
  • Thread Type: covers Metric Coarse and Metric Fine, with UNC and UNF available on request.
  • Size Range: produced from M2 to M20, with special sizes available on inquiry.
  • Surface Finish: supplied bright or with TiN and TiCN coatings for extended tool life.
  • Standards Compliance: geometry follows DIN 371 and DIN 376 specifications.
  • Helix Angle: ground at 35 to 45 degrees to effectively lift chips out of blind holes during cutting.

Key Features

  • Helical flute design pulls chips backward and out of blind holes
  • Steep helix angle suited to long-chipping, gummy, or stringy materials
  • Reduces the need to reverse the tap to clear chip buildup
  • Available in different helix angles to match material chip behaviour
  • Manufactured from high speed steel for consistent cutting performance
  • Suitable for both blind hole and through hole applications
  • Ground with a polished flute surface to reduce cutting friction
  • Sized to standard metric drill charts for straightforward tool selection

Applications of Spiral Fluted Taps - Torpedo Series

  • Threading blind holes in stainless steel components
  • Tapping aluminium castings and machined parts
  • Producing threaded holes in gummy or work-hardening alloys
  • Working on brass and copper fittings in blind hole applications
  • Threading mounting holes in machine tool bodies
  • Creating threaded connections in hydraulic and pneumatic fittings
  • Tapping electrical enclosures with limited hole depth
  • Producing threaded holes in aerospace-grade alloy components
  • Working on precision instrument housings
  • Threading blind holes in mould and die components

Advantages of Spiral Fluted Taps - Torpedo Series

  • Clears chips effectively from blind holes without repeated tap reversal
  • Reduces the risk of chip packing and tap breakage
  • Handles long-chipping materials better than straight flute alternatives
  • Produces cleaner thread finishes in stringy or gummy metals
  • Works reliably across both blind and through hole setups
  • Suited to precision work where thread depth control matters

Why Choose Genuine Enterprises

Blind hole tapping doesn't leave much room for error, since a packed chip at the bottom of the hole can snap a tap before anyone notices something's wrong. The Torpedo Series is manufactured with helix angles matched to how different materials actually form chips, rather than a single generic angle applied across the board. Genuine Enterprises verifies chip evacuation performance on stainless steel and aluminium before releasing a batch, since these are the materials where blind hole tapping tends to go wrong first.

 

Buyers researching a spiral fluted taps supplier in India often find that helix angle options are limited to one or two generic choices, which doesn't account for how differently materials like aluminium and stainless steel actually cut. Genuine Enterprises manufactures across a wider range of helix angles, giving buyers a tap that's actually matched to their material rather than a close-enough substitute.

1.Why are spiral fluted taps preferred for blind holes? 

Because the helical flutes pull chips upward and out of the hole as the tap cuts, rather than pushing them down where they'd pack at the bottom.

2. Can spiral fluted taps also be used in through holes? 

Yes, they work well in through holes too, though spiral point taps are generally faster for that specific application.

3. What materials benefit most from a spiral fluted tap? 

Stainless steel, aluminium, and other alloys that produce long or stringy chips see the biggest benefit from this flute design.

4. Does the helix angle need to match the material being tapped? 

Yes, a steeper helix angle generally works better for gummy or long-chipping materials, while a shallower angle suits shorter-chipping metals.

5. Are these taps as fast as spiral point taps in production settings? 

Not typically. The deeper flute design that helps with chip evacuation also means these taps generally run at somewhat lower speeds than spiral point taps.
