Four things we need from you.
Diameter
Cutting diameter in mm. Sub-0.5 mm drills need the short shank and a dedicated taper holder.
Diameter range
The full range the geometry ships in. Anything inside it is available without a redesign quote.
Coating
Black oxide, bronze, DLC or uncoated. Coating decides the material it may touch.
Flute count
1 to 4 flutes. More flutes mean shorter chips and higher rigidity on micro bores.
Matched applications.
PCB & electronics
Plated hole drilling in CCL and ENIG boards, where a clean, burr-free entry is the acceptance criterion.
Medical devices
Titanium, nitinol and sintered stent hardware — small diameters, long life, tight roundness.
Precision sheet & stamping
High-volume countersinking and cross-drilling in stainless and spring steel.
