Upgraded Drills Increase Stability with Low Thrust Forces

The Dormer Force X upgrades the geometry, corner design and edge preparation of the MPX solid carbide drill family. The upgrade applies to the 3×D R457, 3×D R458, 5×D R453 and 5×D R454, bringing them in line with the 8×D R459.

With a titanium aluminum nitride (TiAlN) coating, the drills are suitable for a range of machines and materials such as stainless steel, steel alloys, cast iron and non-ferrous materials. All Force X drills include continuously-thinned web technology designed to reduce thrust requirements during drilling. They also feature edge preparation that protects the cutting area and prevents premature chipping and flaking. A strong corner design across the range also increases stability and reduces the forces encountered when exiting the workpiece, according to the company.

The micrograin carbide substrate, along with the TiAlN coating, is said to offer high wear resistance and increased tool life, while the 140-degree split-point geometry provides centering capabilities and low thrust forces.

The company offers both solid and coolant feed options to improve cutting efficiency and chip evacuation.
