GSS TOOL MART 5 Pc 1/2" x 1/2" x 4" HSS M2 Square Tool Bit Blanks. Upgrade your machining capabilities with this 5-piece set of premium M2 High Speed Steel (HSS) tool bit blanks — ideal for grinding your own custom cutting profiles for turning, facing, boring, threading, chamfering, and fly cutting.

Made from premium M2 HSS, these blanks deliver excellent wear resistance, toughness, and heat resistance, holding an edge through sustained cuts on mild steel, alloy steel, tool steel, and other ferrous materials. Because they come unground, you can grind each blank to the exact profile your job needs — a right-hand turning tool, a boring bar tip, a custom form tool, or a fly cutter bit — making this set a flexible foundation for lathe, milling, and shaper work rather than a fixed set of pre-ground shapes.
