Solid Carbide Micro Drill with Through Coolant Capability

Walter DB133 Supreme carbide micro drill

Walter offers the Supreme DB133 solid carbide micro drill with internal and external coolant capabilities.

"The use of Walter grades WJ30EL and WJ30ER, specifically for micro drills, ensures that the drills exhibit enhanced wear resistance. The 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," said a company spokesperson.

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

The DB133 drills, with their 140° point geometry, are available in diameter range from 1/32" to 5/64" and 0.5 mm to 2.95 mm. Length to diameter ratios (L/D) of 5, 8 and 12 x Dc are standard. This drill design is suited for 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. 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.
