Step-by-Step (Hand Tapping Guide)

Prepare: Drill the correct tapping size, deburr and clean the bore.
Secure: Clamp the workpiece firmly to avoid tilt or misalignment.
Lubricate: Apply cutting oil/paste to bore and tap to reduce friction.
Align & start: Keep the tap perpendicular and turn it evenly clockwise by hand.
Cut to depth: Continue with steady pressure until the target depth is reached.
Finish: Back the tap out, clean the bore and check with a matching screw or gauge.

Tip: For premium results, use a rougher, intermediate and finisher sequence where applicable.
