Walter USA's D3120 Drill Provides Stability with Reliable Chip Removal

Built to provide trouble-free drilling in virtually all conditions, Walter USA’s D3120 indexable-insert drill features square positive inserts with four cutting edges, reducing cost per edge. Available in five diameter sizes ranging from 0.63" to 1.654" (16 to 42 mm) and with lengths of 2×D, 3×D and 4×D, the drill is said to deliver process reliability with simple and efficient chip removal, two coolant channels and polished flutes. Hardened and polished surfaces protect against friction and improve coolant flow. The D3120 is suitable for ISO material groups P (steels), M (stainless steels), K (cast irons), N (nonferrous) and S (super alloys).

For easier use, the drill has one indexable insert shape for both outer and inner seats and a measuring collar for diameter identification. Torx Plus screws provide secure insert clamping and stability in all working conditions, the company says. 

Walter’s Tiger-tec Silver grades increase the drill’s wear resistance because of its aluminum oxide layer with optimized microstructure. Grades available for the D3120 include:

• WKP25S and WKP35S for ISO steels, cast irons, and good or moderate conditions;
• WSP45S for steels, stainless steels, super alloys and difficult machining conditions;
• WK10 for aluminum; and
• WXP40 primarily for central inserts.
