Deep-Hole Drilling without Piloting

WIDIA™ TOP DRILL S+™ 12 x D

The versatile TOP DRILL S+ provides reliable performance across a broad

scope of applications, including alloyed and unalloyed steel, cast iron, and

some stainless steels and high-temperature alloys. TDS+ is now available

in 12 x D, adding to its already wide range of options from 3–8 x D.

TOP DRILL S+ 12 x D

TDS+ 12 x D is capable of drilling an array of materials. The 4-margin land confi guration offers stability, minimises chipping and jamming, and promotes chip evacuation. Because TDS+ 12 x D does not require a pilot drill, it increases effi ciency by reducing the number of steps required for basic applications.

  • 12 x D fi ts the gap between 8 x D and 15 x D.
  • One drill that covers all materials.
  • Can be used without a pilot.

Extra stability The TDS+ 4-margin land design from head to end of fl ute provides stability in cross holes and inclined exits.

Excellent centring capability

Easy chip evacuation Minimised chip jamming The TDS+ utilises the same technology developed Special gash and fl ute form for effective for WIDIA deep-hole drills. The polished surface chip formation across a variety of materials. enables effective chip evacuation from deep holes.
