30% higher productivity in aluminium

The new DC166 range of special drills from Walter for series

manufacturers

Walter is launching a newly developed solid carbide step drill for aluminium in the form of

the DC166. This special tool with through coolant is specially designed for minimum quantity

lubrication (MQL) or cooling with emulsion. The DC166 will be of interest to all

manufacturers who make products in large batches, especially those in the automotive

industry. When machining aluminium components with many holes or drilling very deep

holes, the DC166 can boost productivity by 20 to 30% compared with straight-fluted drills.

This improvement is due to increasing the feed rate;this is achieved by using a special

cutting edge geometry with a tapered point and very sharp cutting edges, along with

polished flutes. The sharp edges are perfect for soft materials like aluminum, while the point

tapering and polished flutes improve chip evacuation.

Going above and beyond the efficiency offered by a normal step drill that combines two or

more work steps in a single tool, the DC166 not only reduces cycle times by increasing

productivity – it also improves process reliability. The drills in the DC166 range measure

between 4 and 20 millimetres in diameter and come in lengths of up to 30 × D. They can be

used on all aluminium materials, including cast and wrought alloys. Typical areas of use

include engine blocks, gear housing, electric motors or pumps, chassis components like pivot

bearings and wheel bearings, or, more generally, aluminium components with lots of deep or

uniform holes. Walter is offering its customers the new special tool in three variants – the

DC166, DC266 and DC366 – depending on the geometry and shape of the flutes. They will

be available to order normally or via Walter Xpress with shorter delivery times (no more

than approx. two weeks).
