126 MMS August 2017 mmsonline.com TOOLING AND WORKHOLDING · The KM-64 · drills include continuously thinned web technol- ogy 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, the company says. The micrograin carbide substrate, along with the TiAlN coating, is said to offer high wear resis- tance and increased tool life, while the 140-degree, split-point geometry provides centering capa- bilities and low-thrust forces. The company offers both solid- and coolant- feed options to improve cutting efficiency and chip evacuation. Dormer Pramet, call 800-877-3745 or visit dormerpramet.com.
