Tungaloy America has added the AH9130 insert grade to its DrillForce-Meister line of exchangeable-head drills designed for hole diameters ranging from 20-41 mm (0.787″ to 1.614″).

AH9130, consisting of a PVD coating layer optimized for drilling applications with a dedicated carbide substrate, is the latest insert grade specifically developed to provide significant tool life improvements and more predictable wear patterns in holemaking applications of ISO P (steel), ISO M (stainless steel) and ISO K (cast iron). Seventeen SMP-style inserts have been released in the latest grade, covering diameters from 20-35 mm (0.787″ to 1.378″). In addition to Tungaloy’s versatile-grade AH725 which covers most ISO materials, AH9130 is said to provide the DrillForce-Meister line with added process security and tool life improvements in ISO P, M, and K applications.

DrillForce-Meister incorporates a exchangeable-drill head designed to efficiently open large diameter holes cost-effectively. It features an asymmetric V bottom which is fully supported in a matching pocket of the drill body for accurate edge position repeatability and secure insert retention. Large contact surfaces of the drill head and pocket are also said to help the drill withstand heavy cutting loads in aggressive drilling operations. Flute design provide smooth chip control and evacuation in various materials.

According to Tungaloy, the DrillForce-Meister also eliminates the need for regrinding and recoating. Simple drill head exchange ensures dimensional stability and tool life predictability.
