Tips for best results

• Ensure the workpiece is properly drilled to the recommended pilot size before tapping and maintain a steady, clockwise rotation without forcing the tap.
• Apply a light threading fluid or cutting oil to reduce friction, extend tap life, and achieve cleaner, more accurate threads.
• Clear chips frequently and back off slightly to break the chip if the tap begins to bind.

Ideal for machinists, maintenance technicians, metal fabricators, and DIY enthusiasts who demand dependable, repeatable internal threads without compromising accuracy or reliability.
