When Walter Cutting Tools first launched the DC170 Supreme, the “Ikon of drilling,” it was like nothing the market had ever seen before. The special land design of the solid carbide high performance drill not only doubles as a regrinding scale but also enables the drill to be continuously guided. Coolant is washed around the lands when drilling, which reduces oscillation and optimizes the cooling process. Directly behind the insert corner, where conventional run-of-the-mill drills quickly reach their limits, the DC170 Supreme features a substantial carbide base that provides the drill with extra stability. The benefits of this really evident under difficult conditions, such as inclined exits, cross holes and high temperatures. The polished flute and the WJ30EJ grade ensure excellent chip removal.

With the two new drills measuring 25 × Dc and 30 × Dc , Walter is completing its DC170 Supreme range. The new additions to the existing variants – the 3, 5, 8, 12, 16 and 20 × Dc – mean that the DC170 Supreme can now also be used to drill very deep holes in all ISO P and ISO K materials. These drills offer a 50% longer tool life and up to 35% faster run rates than conventional solid carbide drill bits. This is a huge advantage for users working in mass production who need to gain output. It also reduces the risk of the tool breaking when processing expensive workpieces.
