Miranda Solid Carbide Stub Drills — DIN 1897, AlTiN Coated, 1mm to 20mm

When hole accuracy matters more than depth, Miranda stub drills are the answer. Shorter than jobber drills by 30-40%, these DIN 1897 carbide stub drills deliver superior rigidity and less deflection — which translates directly into tighter hole tolerances and better surface finish. The 2.5xD depth ratio and compact overall length make them ideal for shallow holes, thin plates, and applications where the drill needs to be as stiff as possible. Same AlTiN coating and 140° self-centering point as the jobber series, so you get identical cutting performance in a more rigid package. Available from 1.00mm to 20.00mm diameter. If you are drilling holes shallower than 2.5 times the drill diameter, always choose a stub drill over a jobber — you will get better accuracy, longer tool life, and fewer broken drills. Available at Shri Narayan Machinery LLP in Noida.

Frequently Asked Questions — Solid Carbide Stub Drills

Use a stub drill whenever your hole depth is less than 2.5 times the drill diameter. The shorter flute length gives you 30-40% more rigidity, which means tighter hole tolerances (IT7-IT8 vs IT9-IT10 for jobber drills), better surface finish, and significantly less risk of drill breakage — especially in smaller diameters below 3mm where jobber drills are prone to snapping.
