SST (Super Speed Tip) drill bits from Walter Surface Technologies are engineered to last longer, perform on a variety of materials and drill more holes faster. Self-centering split point prevents the “walking” effect on curved surfaces and allows for the drilling of any size of hole in a single operation. The drill bits’ high-flow spiral and chisel edge design maximize chip evacuation, and the field-proven SST heat and surface treatment reduces friction and increases chip flow, the company says. Available in a variety of bit and tap sizes, SST drill bits are made with an exclusive M35 cobalt blend and are designed with a quick shank to ensure fast and secure tightening in handheld tools.
