New Micro Drill from Walter Delivers High Precision and Productivity

The Supreme DB133 solid carbide micro drill features a superior thru coolant capability

Waukesha, WI—Walter has unveiled the new Supreme DB133 solid carbide micro drill with internal and external coolant capabilities. These new drills are key to establishing precise, reliable working processes and achieving significantly longer tool life in steel, cast iron and nonferrous materials (ISO P, K and N workpiece groups).

The use of Walter grades WJ30EL and WJ30ER specifically for micro drills, ensures that the drills exhibit superior wear resistance. In addition, the new cutting-edge geometry increases process reliability and optimized dimensions allow for maximum stability, even with the smallest drills. The uniform finish on the drill cutting edges and tight tolerances ensure that the surface finish of the drilled holes is excellent.

 With the special flute geometry, the chips (swarf) are evacuated effectively. This means that hole depths of up to 12 x Dc can be easily achieved. Oil or emulsion can both be used as a coolant with these drills. For deeper holes beyond 8 x Dc, Walter has also introduced a corresponding line of pilot micro drills, the DB131.

The new DB133 drills, with their 140° point geometry, are available in diameter range from 1/32-5/64 in. and 0.5 to 2.95 mm. Length to diameter ratios (L/D) of 5, 8 and 12 x Dc are standard. This new drill design will be of interest to users in general manufacturing, mold and die making, medical, energy and automotive industries and any other areas where small diameter, deep holes, are required.

 The Supreme designation indicates the highest level of technology and performance available. The Supreme lineup of products is one of three

designations to Walter product technology—Perform, Advance, Supreme.

The Perform tools are products that provide an economical solution with focused importance on price. The Advance tools are products which are efficiently balanced between price and performance.

Walter, a global leader in the metalworking industry for over 100 years, offers a wide range of precision tools for milling, turning, drilling and threading applications. The company helps customers in the aviation and aerospace industries, automotive, energy, and general industry improve process reliability and increase productivity. As an innovative partner capable of creating digital process solutions for optimal efficiency, Walter is pioneering Industry 4.0 throughout the machining industry.
