Walter has introduced the D3120, an indexable insert drill built to provide trouble-free drilling in virtually all conditions. It features square positive indexable inserts with four cutting edges, enabling it to reduce cost per cutting edge.

Available in five diameter sizes ranging from 0.63-1.654-in (16-42 mm) and with 2, 3, 4 x Dc, the new drill delivers maximum process reliability with simple and efficient chip removal, two coolant channels and polished flutes. Superior protection against friction is provided by the D3120 hardened and polished surfaces. This combination of surface hardness and improved coolant flow results in reduced wear on the drill surface.

The new drill is easy to use since it has one indexable insert shape for both outer and inner seat, and a measuring collar for easy diameter identification. The drill is suitable for ISO material groups P (steels), M (stainless steels), K (cast irons), N (nonferrous) and S (super alloys). Torx Plus screws give it secure indexable insert clamping and high stability in all working conditions.

The D3120 features long tool life thanks to Walter Tiger·tec Silver grades. Tiger·tec Silver features increased wear resistance due to its unique aluminum oxide layer with optimized microstructure, as well as low wear due to the extremely smooth rake face it creates. Tiger·tec Silver grades available for include WKP25S and WKP35S for ISO steels and cast irons and for good or moderate conditions; WSP45S for steels, stainless steels and super alloy materials and for difficult to machine conditions; WK10 for aluminum and WXP40, primarily for central inserts.
