Cutting tools come with replaceable tips or inserts as they are commonly called. In these, the cutting edge consists of a separate piece of material, either brazed, welded or clamped to the tool body. Cubic boron nitride, polycrystalline diamond, cemented carbide are some examples of materials used for tips. A cutting tool generally comes with a blade at the end of the shank. Using the right cutting tool is important for any project- the wrong tool can make it very difficult.
Walter unveiled the new Supreme DB133 solid carbide micro drill which has both internal and external capabilities making it a connoisseur of carbide cutting tools. The drills are the key to establishing precise reliable working processes in addition to achieving significantly longer tool life in steel, cast iron, and, nonferrous materials, i.e ISO P, K and, N workpiece groups.
The Following Are the Best Features of The New DB133 Carbide Micro Drills:
1. Wear Resistance
The use of Walter grades WJ30EL and WJ30ER are specifically for micro drills, ensuring that the drills exhibit superior wear resistance. Also, the new cutting-edge geometry increases process reliability and optimized dimensions for maximum stability, even with the smallest drills.
2. Flute Geometry
With the special flute geometry, the chips or swarf are evacuated effectively which means that hole depths of over 12 x Dc can be easily achieved. Oil as well as emulsion can be used as a coolant with these drills. For deeper holes beyond 8 x Dc, Walter has introduced a corresponding line of pilot micro drills, the DB131.
3. Diameter Range
The new DB133 drills with their 140-degree point geometry are available in a diameter range from 1/32-5/64 in. and 0.5 to 2.95 mm. The length to diameter ratios of 5, 8, and 12 x Dc are standard.
4. Uniform Finish
The uniform finishes on the drill cutting edges and tight tolerances ensure that the surface finish of the drilled holes is excellent. The 360-degree coolant coverage offers maximum cooling effect. The optimal tool use leads to reduced production costs.
5. Wide Range Of Uses
The new drill design is of interest to users in general manufacturing, mold and dies making, medical energy and automotive industries as well as other areas where small diameter, deep holes are required.
