HSS Steel Flat Bar Strip Metal Plate 3-200mm Width 200mm Long Lathe Turning Tool

Match the thickness to your tool post slot height and the width to the desired tool width. For a standard 8 mm × 8 mm turning tool, select 8 mm thickness and 8 mm width. For a parting blade, a thin width (3–6 mm) with a taller thickness (8–12 mm) is typical. Refer to your lathe's tool post specification before ordering.

Yes. HSS flat bar is the standard raw material for grinding single-point turning tools, parting blades, boring bars, and form tools. Use a bench grinder with an aluminium oxide or CBN wheel, keeping the workpiece cool with water or air to avoid drawing the temper.

HSS performs well on mild steel, aluminium, brass, and many engineering plastics. For hardened steel or stainless steel at higher cutting speeds, carbide tooling is generally preferred. HSS remains a practical choice for low-to-medium speed operations and hand-ground custom profiles where carbide blanks are impractical.

HSS contains chromium and other alloying elements that provide moderate corrosion resistance, but it is not stainless. Store bars in a dry environment and apply a light coat of machine oil or rust-preventive spray if storing for extended periods. Wipe clean before use.

Mild steel flat bar is a general-purpose structural material with low carbon content — it is soft, easy to weld, and not suitable for cutting tools. HSS flat bar contains tungsten, molybdenum, chromium, and vanadium alloying elements that give it high hardness, wear resistance, and the ability to retain a cutting edge at elevated temperatures. Use HSS when you need to grind a functional cutting tool.

Absolutely. HSS flat bar is also used for precision scrapers in surface plate work, small fixture components requiring high wear resistance, and custom blades for woodturning. The consistent rectangular cross-section and ground surfaces make it easy to clamp and position accurately in any workshop setup.

Each order includes one (1) piece of HSS flat bar in the thickness, width, and length combination you select. If you need multiple pieces or different sizes, simply add each variant to your cart separately.
