An osteotome is primarily made by Investment Casting. Investment casting builds a wax pattern, coats it in a ceramic shell, melts the wax out, then pours metal into the cavity. It gives near-net shape with fine detail. Below is the full route to make an osteotome, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How an osteotome is made
The usual route, raw material to finished part. The amber step is where the osteotome gets its basic shape.
Material
Cut martensitic stainless bar (420 or 410 grade) sized for the osteotome.
Investment Casting
Form the blank.
Tooling Medium to high Tolerance ±0.1 to 0.5mm Lead 3 to 8 weeks
Trimming
Trim the flash and pierce the rings, bows or finger holes.
Milling the pattern
Mill the shank and working end, and cut the serrations, teeth, ratchet or cutting edge.
Tooling None Tolerance ±0.125mm, to ±0.025mm Lead 1 to 10 days
Heat treatment
Harden and temper the working ends for wear resistance and spring.
Tooling n/a Tolerance can distort Lead days
Grinding and polishing
Grind the profile and satin or mirror polish the osteotome.
Tooling Low (wheel) Tolerance ±0.002 to 0.02mm Lead days
Passivation
Passivate or electropolish to restore the corrosion-resistant chromium-oxide layer.
Tooling Low Tolerance removes microns Lead days
Marking and inspection
Laser-mark, ultrasonic clean, then inspect the action, alignment, sharpness and finish.

Cost
What an osteotome should cost
Near-net and great finish, so it saves machining on complex parts; the wax die is the cost to amortise.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for an osteotome at your volume, in your currency, are in the dossier.

What does an osteotome cost?
It depends on size, tolerance and volume. As a rough ballpark it starts around $360 to 1005 per part at 1 off and falls with quantity. The dossier gives should-cost at your exact volume and currency. A model estimate, not a quote.
What material is an osteotome made from?
Common choices are Stainless 17-4PH / 316; Carbon/alloy steel; Superalloy (Inconel).
What is the main process for an osteotome?
Investment Casting. Complex, detailed metal parts needing a good finish and tight tolerances, including superalloys and turbine hardware.
