Product Specifications:
This 56mm indexable U drill is specialized for shallow, large‑diameter holes (max. 112mm depth) in heavy structural steel, excavator booms, and crane bases. The 2D design allows a very rigid C40 shank and low RPM range (500‑700), which manages the high torque required for large holes. Feed rate of 0.06‑0.08 mm/r produces strong, manageable chips.
WCMX080412 inserts feature three cutting edges and a positive rake geometry that reduces cutting forces, making this drill suitable for older machines with limited power. Double helix internal cooling keeps the insert cool even at low speeds. Typical applications include flange holes in pressure vessels, mounting holes for heavy equipment, and through‑holes in thick plate for structural steel. Because the depth is limited to 2D, pecking cycles are rarely needed, saving time. For materials like A36 steel or 4140 annealed, this U drill delivers long tool life. Alternative insert grades for stainless steel and high‑temperature alloys are available. Upgrade your large‑hole drilling with this cost‑effective U drill.
