VT machining offers CNC Sinker EDM for 1095 Steel (UNS G10950 / C100S / SK4), typically supplied annealed or hardened. Very high carbon; machined annealed then hardened for blades and springs.
CNC Sinker EDM Notes for 1095 Steel
Cavities and blind forms in 1095 Steel are sunk with graphite or copper electrodes, directly in the hardened state.

Does CNC Sinker EDM 1095 Steel require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
What is CNC Sinker EDM 1095 Steel and how is it done?
CNC Sinker EDM 1095 Steel refers to sinker (die-sink) EDM burns a shaped electrode into metal to form precise cavities and blind features. Applied to 1095 Steel — strong, economical and widely available — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
What tolerances can you hold for CNC Sinker EDM 1095 Steel?
Achievable tolerances for 1095 Steel EDM machining depend on the alloy, geometry and feature size. EDM holds tolerances to around ±0.002 mm with no cutting force on the part. Exact figures are confirmed against your drawing callouts.
Can VT machining make custom 1095 Steel parts to my drawing?
Yes. 1095 Steel EDM 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.
Why is 1095 Steel a good choice for CNC Sinker EDM?
1095 Steel is strong, economical and widely available, which makes it well suited to CNC Sinker EDM. We tune the process to the alloy so the finished 1095 Steel EDM machining part meets your dimensional and functional requirements.
Can you EDM-machine hardened 1095 Steel?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult 1095 Steel can be machined to fine detail and tight tolerance without distortion.
