Tungaloy: DrillMeister’s DMH Drill Heads Include Additional Diameters for the 6.0-9.9 mm and 20.0-25.9 mm Ranges

Tungaloy has expanded its DrillMeister exchangeable-head drill system by adding 24 more DMH drill heads that are designed to resist fracture damage. This addition is for hole diameters ranging from 6.0 to 9.9 mm (from .236″ to .390″) and from 20.0 to 25.9 mm (from .787″ to 1.020″).

DrillMeister features superior cutting performance of solid carbide drills and the ease-of-use of the exchangeable head drill system. A single drill body can hold five different styles of drill heads, which are available in general-purpose DMP style, DMC for high precision holes, DMF with flat edges ideal for counterboring, DMN for non-ferrous applications, and DMH with enhanced drill corner geometry for drilling thin walls.

The DMH drill head geometry is designed to protect drill corners and provide effective chip evacuation, making the drill head suited for applications that involve drilling holes through thin-walled sections of workpieces. The increased cutting edge strength resists thin-wall snapback and wear from exit burrs, preventing drill edges from fracture damage during machining for minimum machine downtime. The strong cutting edge also makes the DMH drill head suitable for drilling extremely hard metals.

AH9130 grade provides DMH drill heads with a good balance of wear and fracture resistance, ensuring exceptional tool life performance and wear predictability, particularly in carbon steel and alloy steel.
