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.
Minimised chip jamming
Special gash and fl ute form for effective
chip formation across a variety of materials.

Easy chip evacuation
