PRECISION TWIST DRILL 092358 29/32″ Size 118° Cobalt Silver & Deming Drill Hot Deal

Choose Precision Drills for All-Purpose Applications. Precision presents its 1/2 inch reduced shank Silver & Deming Drills for applications on low and medium tensile strength materials. The drills are made from cobalt steel which offers greater applications than high-speed steel. The heavy-duty cobalt core guarantees increased strength and reduced breakage. The unique spiral flute design improves chip ejection and coolant flow to the point. 118° split-point prevents “walking” and provides aggressive cutting. All drill bits offered in this series are surface treated and appear to have a black coating. It helps in significantly reducing friction and thereby, offers higher feed rates. This makes it ideal for workpiece material made of Steel, Stainless Steel, High-Temp Exotic alloy, Non-Ferrous, Cast Iron, Plastics. The lower helix angle of 30° can wrap slowly and is used in drilling hard materials including brass. C8R56Co model Silver & Deming drills from Precision are offered in over 30 different sizes of 1-1/2 inches and under. The model has a round & reduced shank to provide superior grip in heavy-duty applications. The brand Precision is from its parent company Dormer Pramet which has made a formidable presence in delivering high-quality cutting tools since 1952. Grown from the US suburbs, the brand Precision is now a recognized general-purpose industrial manufacturing product hosting an extensive portfolio of HSS and solid carbide drills, taps, countersinks, and reamers. Can be used in electric drills and drill presses with 1/2″ capacity drill chuck
