Technical FAQ
Frequently Asked Questions By Hand Tool Procurement Managers
Century industrial files are forged from high-carbon alloy tool steel (T12 / 1095 class) and subjected to controlled vacuum heat treatment to reach HRC 62–66 hardness. This metallurgy ensures crisp tooth edges, uniform wear resistance, and long service life under heavy shop conditions.
Bastard cut features coarse tooth pitch for aggressive initial stock removal. Second cut offers medium tooth density for stock shaping and moderate finishing. Smooth cut features tight tooth spacing engineered for precision deburring, smooth polishing, and close-tolerance work.
Yes. We work closely with international hardware distributors, automotive aftermarket chains, and tool brands to provide private-label branding, customized retail packaging cards, barcoded vinyl sleeves, and tailored assortment displays.
Select chainsaw file diameters based on the chain pitch specification: 5/32 in (4.0 mm) for 1/4 in and 3/8 in Low Profile chains, 3/16 in (4.8 mm) for .325 in chains, and 7/32 in (5.5 mm) for standard 3/8 in and .404 in pitch chains.
Use a specialized file card or wire brush regularly to clear pinned metal chips from tooth gullets. Store files in separate vinyl sheaths or racks to prevent teeth from striking adjacent metal tools, and apply light anti-corrosion oil during extended storage.
