The new D4120 drill tip from WalterClick image to enlargeThe D4120 is an indexable insert drill from Walter that combines superior performance, enhanced precision and cost-effectiveness.

Hardened and polished flutes facilitate easy chip removal and high process reliability, while the drill body features two independent thru-coolant channels.

Precision in the hole diameter is enhanced by balancing the cutting forces between the center and peripheral insert (geometries A57, E57 and E67).

The series includes drills with up to 4 x Dc in inch sizes, 5 x Dc metric and in diameters up to 1.375 in. and 59 mm.

The combination of D4120 drill bodies and inserts with CVD and PVD grades WKP25S, WKP35S, WSP45 and WXP40 offers cost-efficient advantages and flexibility. The drills are ideal for difficult machining operations, such as cross holes, curved surface entry, chain drilling and inclined entry and exits.

Use them on steels, stainless steels, cast irons, nonferrous materials and super alloys (ISO materials P, M, K, N and S) for general metalworking, die and mold making, and the energy and automotive industries.

Walter also offers the D4120 in special dimensions via Walter Xpress rapid specials and quotations program.
