The 5/16" High Speed Steel Tool Bit Blank is a versatile and essential tool for any metal lathe operator. Made from high speed steel, this tool bit is capable of withstanding high temperatures and stress during use, ensuring a long lifespan.

The tool bit has been end ground to a precise 0.01" wide parting blade and sharpened on both ends to a 60° angle, making it ideal for creating precise and accurate threads in a variety of materials. Both ends are offset, with one end designed for threading near a left shoulder and the other for threading near a right shoulder. This makes it an ideal choice for a wide range of threading applications.

Whether you're working with aluminum, steel, or other metals, this tool bit is up to the task. Its sharp edge and fine tip allow for clean and professional results every time.

Andrew E. ★★★★★

Ground this down to the exact profile I needed for a fine thread pass and it held its edge beautifully through a dozen parts. The high speed steel really does shrug off the heat without any visible bluing.

Sofia P. ★★★★★

Finally got around to grinding this 5/16" HSS blank for threading, and it held an edge perfectly through a dozen passes on steel rod. The high speed steel material really does handle the heat without breaking down.

Emily A. ★★★★★

Used this on my metal lathe for the first time today and the high speed steel held up perfectly even after several heavy passes. The cutting edge stayed sharp through the whole job, no sign of wear.
