Walter's new solid carbide, internal coolant supreme drill designed for steel and cast iron applications
The new Walter Drivox∙tec™ IKON DD170 Supreme solid carbide drill features a unique design with a full radial margin and internal coolant for holemaking in steel and cast iron (ISO P and K material groups). The WJ30EY-grade drill has a Krato·tec® coating to significantly enhance tool life compared to its predecessor -- the DC170.
The full radial margin provides 360° support to the cutting edge while in the cut. This design helps the drill to provide maximum process reliability in challenging applications, such as cross-hole drilling and those involving inclined exits, without having to reduce the feed rate. The radial margin support also ensures exceptional smooth surface finishes, hole roundness and vibration-free cutting.
The DD170 Supreme drill features 12 coolant grooves, which have a new profile for enhanced process reliability when machining relatively soft, gummy materials such as AISI 1010 or AISI 1018. The 12 grooves also allow for more possible regrinding operations. The coolant grooves effectively cool the cutting edge, significantly extending tool life even at elevated cutting feeds. The drill can be used with emulsion or oil coolant.
The tool's variable clearance tip geometry provides the best centering capabilities, eliminating pilot drilling up to 12 x Dc. The diameter range is from 3 to 20 mm, including factional inch sizes. The tool can drill 3 x Dc in according with the DIN 6537 standard, 5 x Dc in accordance with DIN 6537 long, 8 x Dc in accordance with the Walter standard and 12 x Dc in accordance with the Walter Norm standard. The drill has a 140°-point angle.
Areas of use include mold and die making, general mechanical engineering and the automotive, aerospace and energy industries.
