2 Product Information The combination of curved cutting lips & X-type Web Thinning provides a unique point geometry that separates this drill from the conventional. When drilling materials that produce long stringy swarf, the problem faced with conventional twist drills is that the swarf wraps around the drill. This lends itself to poor productivity, as insufficient coolant penetrates into the cutting area & the evacuation of the swarf is inconsistent or erratic. The DX Series drill eliminates these issues, due to its generated curved cutting lips, the chips produced are short. Notes on Drilling 1. Step feeding or pecking is required for drilling greater than 3 x diameter 2. When drilling cast surface & black (ie. not machined surface), reduce drilling speed by 20% Stub Jobber Drilling Depth 3xØ 5xØ Catalogue Code D190 D177 HSS Co HSS Co Surface Finish Brt Futura TiAlNano Brt Futura TiAlNano Color Ring & Application W W W W R40 R40 Material: CS1020 Depth 20mm Vc = 166 SFM f = inch/rev Material: Al6061 Depth 20mm Vc = 328 SFM f = inch/rev Point Geometry To aid in the accurate positional & size of the drilled hole, the chisel at the centre of the point has X-type Vweb thinning, this provides the absolute minimal thrust requirements to maintain optimal point stability when drilling. Flute Design 35 flute helix & special flute form allows for non-step drilling of 3xd to 4xd hole depths. Tool Material & Coating Made from Premium Cobalt grade of High Speed Steel (HSSCo) with a supersmooth Futura Nano coating, provides the optimal combination for high heat resistance.
