Composite tools by Karnasch are the future in machining of fiber composite materials

Karnasch's high speed cutting composite tool range includes solid carbide end mills, CVD end mills, PCD end mills, MKD end mills as well as solid carbide drills, PCD drills, spade drills and PCD saw blades. Our composite tools are suitable for 3D copy milling, contour milling, face and step milling, tapping, drilling, circumference milling, deburring, slotmilling, countersinking and sawing.

The Karnasch composite tool range offers versatile solutions for composite materials that are difficult to machine. Karnasch solid carbide composite tools have been specially developed for machining of materials such as aluminum, GRP/CRP, graphite, acrylic, titanium, honey comp and FR4.

One of the latest developments are CVD (chemical vapour deposition) end mills, which have revolutionized the machining of materials in the aerospace and automobile industries. These composite tools are extremely sharp due to their laser-cut cutting edges and ensure a smooth cut with a high-precision cutting tolerance of up to 1µ.

This increases tool lives by up to 300%, prevents delamination and produces very smooth surfaces. Due to special geometries, drilling without cut-outs in GRP/CRP is no problem for Karnasch composite tools.

KARNASCH INTERNAL COOLING

Drills with internal cooling for optimal cooling and lubrication

Maximum resilience for challenging applications.

Karnasch internal cooling guarantees optimal cooling results and presents obvious advantages as compared to external cooling. On the one hand, the cooling of the cutting edge can individually be optimized, with the result that the heat development is considerably reduced. The special power chamber by Karnasch ensures an increased coolant leak - at the same pressure but also at low pressure. On the other hand, Karnasch internal cooling removes the chips more efficiently and improves the overall cutting performance significantly. In addition to higher productivity, Karnasch internal cooling enhances tool lives and prevents premature tool breaking, which in turn leads to considerable cost savings.

Advantages of the Karnasch cooling channel drills

  • Optimal tool life even under highest loads (optimal cooling and lubricating effect)
  • Increased drilling speed
  • Chips are more easily removed from the drilling range
