Technical articles about drill point dies, self-drilling screw manufacturing, and cold-forging tooling.
Practical guide to maximizing drill point die service life: machine alignment, lubrication, feed rate optimization, storage, inspection, and PVD coating strategies for self-drilling screw manufacturers.
Learn what drill point dies are, how they work in cold forging, material options (tungsten carbide vs HSS), and how to choose the right die series (L1-L6) for your self-drilling screw production line.
Compare tungsten carbide and high-speed steel (HSS) drill point dies for self-drilling screw production. Cost analysis, service life, performance differences, and selection guide for fastener manufacturers.
Cross-reference guide for self-drilling screw sizes between IFI (#4-#14) and DIN (ST2.9-ST6.3) standards. Includes drill diameters, wire diameters, and matching drill point die specifications.
