Sumitomo Electric Carbide expands its SMD replaceable drill head line to include 12×D drills. The drill head line supports deep hole making at a lower cost, the company says. Users can buy one drill body to fit as many as five head sizes.
The SMD drill heads feature a radial serration coupling design that promotes high-precision, stable drilling and therefore accuracy and repeatability by affixing the replaceable carbide tips to the drill face. The drill head’s polished flute enhances chip evacuation. The nickel-plated body is said to provide longer tool life than conventional replaceable tip drill bodies. A tough carbide substrate with the company’s DEX coating offers wear resistance at the cutting edge.
The company’s SMDT-MTL drill tips support steel applications, while the SMDT-C tips have a chamfered edge to eliminate breakout in cast iron applications. The SMDT-MEL is designed for machining super alloys, stainless steels and cast iron.
Along with the 12×D drills, Sumitomo’s SMD line also includes 3×D, 5×D and 8×D replaceable carbide tip drills.
