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 configuration offers stability, minimises chipping and jamming, and promotes chip evacuation. Because TDS+ 12 x D does not require a pilot drill, it increases efficiency by reducing the number of steps required for basic applications. • 12 x D fits 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 flute 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 flute 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. T98 widia.com
