2 K-TECH s.r.o Productivity, Creativity & Infinity Nine9 company began in 1994 and with the development of special tools, boring heads and accessories. The Nine9 logo was commissioned in It comes from the Chinese characters meaning long life and durability words which aptly describe all Nine9 tools. 99 is the largest 2 digit number, indicating maximum product endurance. Nine9 tools whilst being special in the indrustry, are standard in our product range. NC Spot Drills, super power drills, boring tools, engraving tools, i-center, NC helix drills, chamfer mill. Those established Nine9 as a market leader and innovator in the cutting tool field.

9 A New Drilling Concept! 0.5xD of spotting Many drill manufacturers and suppliers state that their drills start drilling on the solid material. You can look forward to the following benefits when using the NC Spot Drill to drill a spot that is half of the drilling diameter. Drill Benefits >> K-TECH s.r.o Higher feed rate. Why? Because the drill is guided at the strongest part of cutting edge. Better center position. Why? Because the spotting is done by a single cutting edge which is out of center, and similar to boring operation. Increased tool life. NC Spot Drill Without Spotting 0.5xD Spotting arger Spotting Better center position! onger tool life! Drill has less position accuracy and diameter tolerance. Best result! Higher speed and feed rate. Better position accuracy and diameter tolerance. onger spotting time! Guided at the weakest corner of drill.
