VT machining offers CNC EDM Drilling for 303 Stainless Steel (UNS S30300 / 1.4305 / SUS303), typically supplied annealed. Sulfur addition makes it the most machinable austenitic grade, at the cost of weldability and some corrosion resistance.
CNC EDM Drilling Notes for 303 Stainless Steel
EDM drilling produces small, deep holes and wire start holes in 303 Stainless Steel where a twist drill would wander or break.

Request a QuoteFrequently Asked Questions
Can you EDM-machine hardened 303 Stainless Steel?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult 303 Stainless Steel can be machined to fine detail and tight tolerance without distortion.
Can VT machining make custom 303 Stainless Steel parts to my drawing?
Yes. 303 Stainless 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.
What tolerances can you hold for CNC EDM Drilling 303 Stainless Steel?
Achievable tolerances for 303 Stainless 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.
What is the typical lead time and minimum order for CNC EDM Drilling 303 Stainless Steel?
CNC EDM Drilling prototypes for 303 Stainless Steel can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
Does CNC EDM Drilling 303 Stainless 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 EDM Drilling 303 Stainless Steel and how is it done?
CNC EDM Drilling 303 Stainless Steel refers to fast-hole EDM drilling produces small, deep holes in hard metals, including starter holes for wire EDM. Applied to 303 Stainless Steel — corrosion resistant, strong and hygienic — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
