How to get the best results

Prepare the hole with a suitable pilot drill, apply a light lubricant or cutting oil, and keep the tap square to the workpiece as you turn it slowly. After reaching the desired depth, back off slightly to break the chip and prevent binding. Clean the hole thoroughly after tapping to remove any debris and ensure smooth operation of the mating fastener.

Care and maintenance

Wipe taps clean after use, apply a thin coat of light oil to prevent corrosion, and store in a dry, organized case to preserve edge quality. Proper handling extends tool life and keeps threads crisp for the next job.
