12×D Replaceable Head Drills for Low-Cost, Deep-Hole Making

Sumitomo’s SMD 12×D replaceable head drills allow for deep-hole making at a lower cost. SMD users buy just one drill body to fit up to five head sizes.

Featuring an original radial serration coupling design, SMD drill heads or tips are designed for high-precision, stable drilling. A polished flute ensures good chip evacuation.

The SMD’s nickel-plated body provides longer tool life than conventional replaceable tip drill bodies. A tough carbide substrate with patented DEX coating offers excellent wear-resistance at the cutting edge. A rigid serration coupling system affixes the replaceable carbide tips to the drill face, improving drill accuracy and repeatability. 

Sumitomo offers a range of drill tip styles to improve performance in a variety of materials. The SMDT-MTL drill tip excels in steel applications, while the SMDT-C has a chamfered edge to eliminate breakout in cast iron applications. The SMDT-MEL machines super alloys, stainless steels and cast iron proficiently.

Along with the new 12×D, Sumitomo’s SMD line includes 3×D, 5×D and 8×D replaceable carbide tip drills.
