PLUS – One Tool performs multiple applications
The exciting multi-functional NC Helix Drill from Nine9 has been developed to eradicate ‘non-cutting’ times through its ability to conduct helical interpolation milling, ramping, slotting, counter-boring and drilling with a single tool. This flexibility is emphasised by the requirement for just six different tools for drilling precision holes from 13 to 65mm diameters.
Working on an interpolation cycle, the NC Helix Drill reduces the cutting load on the spindle by ramping at an angle up to 20 degrees whilst the sinusoidal ‘wavy edge’ insert edges break the swarf into fine chips that are easily evacuated from the hole. This excellent swarf control applies to the most difficult to machine materials. In addition, the drill body is available with either a cylindrical shank or as a screw fit holder that can fit most toolholder extension bars on the market. The drills are available with or without through coolant facility for rapid swarf evacuation.
Corresponding with the NC Helix Drill is an insert with two cutting edges per insert and a serrated cutting edge geometry. Produced from a K20F micro grain carbide substrate that is TiAlN coated; the grade and geometry provide remarkable tool life on all types of material from aluminium, carbon steel, low and high alloy steel, stainless steel, cast iron, nickel and titanium alloys. The drill body is offered with shank diameters of 10, 12, 16, 20 and 25mm for drilling holes from 13 to 20mm, 15 to 25mm, 20 to 30mm, 25 to 40mm, 30 to 50mm and 42 to 65mm diameters.
