Kennametal Carbide Deep Hole Drills
HP Solid Carbide Deep-Hole Drills for Steel, Cast Iron, and Non-Ferrous Materials
Primary Application
B27_HPG Series Solid Carbide Drills are the optimum platform for drilling holes up to 30 x D in steel, cast iron, and stainless steel materials. Drill deep holes up to 4x faster than conventional HSS and gun drills. Application of MQL is possible.
The B27_HPS in the new uncoated KN25™ grade now offers the same advantages for drilling in non-ferrous materials such as aluminium, copper, and brass. These series are now available from 2,3–16mm (.09–.63") diameter and in lengths from 15–30 x D.
