VT machining offers CNC Drilling for C260 Brass (UNS C26000 / CuZn30 / Cartridge brass), typically supplied annealed or half-hard. Excellent cold-forming brass; not leaded, so chips are stringy compared with C360.
CNC Drilling Notes for C260 Brass
C260 Brass drills cleanly; we choose point angle and peck depth by hole depth-to-diameter ratio and hold position to the drawing.
For estimating, a 100 × 100 × 10 mm block of C260 Brass weighs about 0.85 kg.

Why is C260 Brass a good choice for CNC Drilling?
C260 Brass is free-machining with good conductivity, which makes it well suited to CNC Drilling. We tune the process to the alloy so the finished C260 Brass machining part meets your dimensional and functional requirements.
Can VT machining make custom C260 Brass parts to my drawing?
Yes. C260 Brass machining is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
What tolerances can you hold for CNC Drilling C260 Brass?
Achievable tolerances for C260 Brass machining depend on the alloy, geometry and feature size. Milling holds positional and dimensional tolerances to around ±0.01 mm, tighter with precision setups. Exact figures are confirmed against your drawing callouts.
What material thickness or size range suits CNC Drilling C260 Brass?
We machine C260 Brass across a broad size range; share your part envelope for confirmation.
