Frequently Asked Questions
What is included in the set?
Each set includes three hand taps of the same metric thread size: a taper tap, a plug tap, and a bottoming tap. This allows you to cut threads progressively for both through-holes and blind holes.
What is the difference between taper, plug, and bottoming taps?
The taper tap has a longer chamfer (8-10 threads) for starting threads in a fresh hole. The plug tap has a shorter chamfer (3-5 threads) that works well for general-purpose threading. The bottoming tap has no chamfer, making it suitable for cutting threads to the very bottom of a blind hole.
Can these taps be used on stainless steel?
Yes, these HSS taps can cut threads in stainless steel when used with a suitable cutting fluid or lubricant. For harder materials like stainless steel, we recommend using cutting oil to reduce friction and prolong tool life.
How do I choose the correct tap size?
Select the tap size according to the required thread diameter. For metric coarse threads, the tap is stamped with the nominal diameter and pitch (e.g., M10 x 1.5). Use a tap drill chart to drill the correct hole size before tapping.
