Walter has introduced the DC183 Supreme solid-carbide drill with three cutting edges to achieve the highest machining volume. The drill has internal coolant channels and can be used with emulsion, oil, and minimum quantity lubrication (MQL).
The drill is coated with the company’s Krato·tec coating to achieve maximum productivity when holemaking. The fracture-resistant aluminum titanium nitride (AlTiN) multiple-layer coating technology was specifically developed for solid-carbide drilling tools. The textured top layer has a high aluminum content to provide good heat, wear, and oxidation resistance; the graded transition layer balances residual stresses; and the base layer prevents cracks from forming in the coating.
These drills are suitable for machining steel, cast iron, and non-ferrous materials. The secondary applications are superalloys and stainless steels.
Standard diameter dimensions for the drill are from 0.118 to 0.630 in. The standard drill can produce holes to 5×Dc in accordance with the DIN 6537 long standard and holes 8×Dc in accordance with the Walter standard.
The drill is available in two grades: WJ30EX, the AlTiN multiple-layer coating; and WJ30EY comprised of the K30F substrate and the AlTiN tip coating.
