Precise to the very last detail

New Walter Titex DB133 Supreme solid carbide micro twist drills: Tool life now up to five times longer

The new Walter Titex DB133 Supreme solid carbide micro twist drills are the key to

establishing precise, reliable working processes and achieving significantly longer tool life. The

use of grades WJ30EL and WJ30ER, developed by Walter specifically for micro drills, ensures

that the drills exhibit superior wear resistance. In addition to this, the new cutting edge

geometry increases process reliability, and optimised dimensions allow for maximum stability,

even with the smallest drills.

The incredibly uniform finish on the drill cutting edge and extremely tight tolerances ensure

that the surface finish on the workpiece is exceptional. Thanks to the special flute geometry,

the swarf is evacuated effectively, even without through coolant. This means that hole depths

of up to 8 x Dc can be easily achieved.

The new solid carbide micro twist drills, with their 140° point geometry, can be used

universally on many different materials in ISO material groups P, K and N. Diameters range

from 0.5 to 2.95 mm. Oil or emulsion can be used as a coolant. This new drill design will be of

particular interest to users in general mechanical engineering, mould and die making, the

energy and automotive industries and any other areas where small diameter, deep holes, are

required.
