Why this tap stands out

• General-purpose, ready for a range of materials. The uncoated HSS tap is ideal for mild steel, aluminum, brass, and other common metals when paired with appropriate cutting fluid. It’s designed to perform predictably across a variety of workshop tasks without the quirks of specialized coatings.
• M22x1, right-hand thread, second lead. The right-hand threading and ISO 529-compliant geometry ensure standard, compatible threads. The second lead design accelerates cutting in through-holes, helping you establish starting threads quickly and reduce overall tapping time.
• Precision-ground for accuracy. Ground surfaces on the tap promote steadier cutting action, smoother chip evacuation, and tighter tolerance control for dependable thread quality in project work or production setups.
• Efficient workflow for shop use. Whether you’re pairing this tap with a hand tap wrench or a light milling setup, the tool’s geometry supports steady advancement, minimal wander, and clear chip formation—key for repeatable results.

Ideal use cases

Use this M22x1 right-hand tap when you need reliable metric threads in through-holes or components that require standardized fastener engagement. It’s well-suited for:

• Repairing or re-tapping threaded holes in mild steel chassis, brackets, or housings.
• Creating new, robust threads in aluminum or brass fixtures for quick assembly.
• Prototyping or small-batch production where consistent thread pitch and fit are critical.

Tips for best results

Maximize life and performance with practical tapping practices:

• Use a sharp, clean drill size appropriate for M22x1 threads and apply cutting oil or tapping fluid to reduce friction and chip buildup.
• Begin with a light, steady feed, then reduce pressure as you approach the finished depth to maintain thread form and minimize chatter.
• In through-holes, allow for chip clearance by periodically backing the tap out to break and remove chips.
• Keep the tap square to the workpiece to avoid cross-threading and out-of-round threads.
