Cut Hardened Bit Driver

What happens here

Following the successful cut of the masonry drill bit, a hardened bit driver (a hexagonal shaft often made from heat-treated tool steel) is placed and clamped firmly within the Work IQ bench vise. The presenter proceeds to cut this even tougher material using the same Milwaukee "Extreme Materials" carbide oscillating saw blade. The cutting action again produces a vigorous display of sparks, confirming the extreme hardness of the bit driver. The blade manages to cut through the material, leaving a visible purple and blue heat discoloration on the severed portion of the bit driver, a clear sign of the intense heat generated during the cut. This test reinforces the carbide blade's effectiveness and durability when cutting highly resilient, heat-treated metals, making it an excellent choice for "extreme materials."

Goal: The same carbide blade is then used to cut through a hardened bit driver, further testing its resilience on extreme materials.
