VT machining offers CNC Drilling for 1045 Steel (UNS G10450 / C45 / S45C), typically supplied normalised or cold-drawn. Medium carbon; can be induction- or flame-hardened.
CNC Drilling Notes for 1045 Steel
1045 Steel 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 1045 Steel weighs about 0.79 kg.
