6-inch Long Reduced Shank Silver & Deming Drills for High-Performance Applications. TTC presents its 3/4 inch reduced shank Silver & Deming Drills for most heavy-duty applications. The unique 3-inch long spiral flute design improves chip ejection and coolant flow to the point. 118� self-centering split point prevents �walking� and provides aggressive cuts. All drill bits offered in this series are surface treated and appear to have a black oxide coating. The coating reduces friction and offers higher feed rates. The lower helix angle of 30� can wrap slowly and is used in drilling hard materials including brass. Silver & Deming drills from TTC Production are offered in over 20 different sizes from 25/32 inch to 1-3/8 inches. All models have 3 flats on the shank to provide superior grip in heavy-duty applications. This brand is a top choice for common materials, short-run jobs, and general-purpose projects. The brand is already used by thousands of small shop machinists, job shops, and do-it-yourself hobbyists everywhere. It features a thorough inventory of carbide and high-speed steel radius and cutting tools, abrasives, holding accessories, and much more. All TTC products are globally sourced and meet standard ANSI tolerances and requirements.
