Advantages of spade drills with quick-change system

Karnasch spade drills consist of two components, the tool holder and the cutting inserts. The spade drills also have an internal coolant supply, which ensures excellent chip removal, even when drilling deep holes.

Spade drills are particularly suitable for CNC machines such as pillar drilling machines and radial drilling machines as well as all traditional or manual drilling machines. Learn more about the advantages of Karnasch spade drills in the following overview.

  1. 1. Only 14 holders are required to cover the diameter range Ø 9.5 - 114 mm.
  2. 2. Internal coolant supply for excellent chip removal even when deep drilling.
  3. 3. The high-precision connection between holder and cutting insert guarantees narrowest tolerances and cutting inserts that are easy to change.
  4. 4. The cutting inserts are made of powder steel or carbide. All cutting inserts also have coatings that are optimized for their intended uses. This combination results in a significantly higher cutting performance and tool life.
  5. 5. Due to the quick exchange of the cutting inserts, the spade drill is immediately ready for use again. It is not necessary, as in the case of conventional steel drills, to recondition or sharpen the complete drill.
  6. 6. The optimized XR cross-sectional cutting edge grinding on the cutting inserts reduces the cutting forces significantly and improves the stability of the entire cutting insert.
  7. 7. The chip breaker results in better chip removal and a lower cutting force.

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
