Product & Application FAQs
What is a spiral point tap used for?
A spiral point tap cuts internal threads in through holes and directs chips forward through the hole exit. This M3–M30 HSS series is intended for metric machine tapping with sufficient clearance beyond the workpiece.
Which thread sizes and pitches are available?
The size chart covers M3–M30 with selected metric coarse and fine pitches. Order by the complete designation, such as M10 × 1.5 or M10 × 1.0, and check the listed shank diameter, thread length, overall length and square width. Not every pitch is available in every diameter.
Which materials is this HSS series intended for?
The catalog lists general steels, alloy steels below HRC 30 and cast steels. Confirm the exact workpiece grade, hardness and chip behavior before selection. Stainless steel, titanium, nickel alloys and hardened steels require a separate application review.
Can I use these taps in blind holes?
This series is intended for through holes. Forward-moving chips need an open exit; use a suitable spiral flute tap for blind-hole applications. Thread length is a tool dimension, not a guarantee of usable full-thread depth.
Are uncoated and TiN-coated taps available?
Yes. The catalog lists uncoated and TiN-coated spiral point options. Select the finish according to the material and tapping conditions, and specify it when ordering. The listed substrate is HSS; a cobalt content or HSS-E grade should not be assumed.
How do I select the pilot hole, speed and feed?
Use a cutting-tap drill recommendation for the exact thread size, pitch, material and required thread tolerance. Synchronize feed per revolution with thread pitch. Select speed and lubrication for the application; the HSS speeds and feeds guide below provides general reference data, not a guaranteed setting for every setup.
What should I check if tapping torque rises or chips accumulate?
Check the measured pilot-hole diameter, tap wear, holder alignment, feed synchronization and lubricant delivery. Make sure the fixture does not block the hole exit and that the chamfer can pass far enough through the workpiece to complete the thread.
Ordering & Customization FAQs
What information should I provide for a quotation?
Send the thread size and pitch, quantity per size, uncoated or TiN-coated finish, workpiece grade and hardness, required thread tolerance and workpiece thickness. Include the machine and holder details or a drawing if tool dimensions are restricted.
Can dimensions, thread specifications and OEM marking be customized?
Custom thread specifications, tool dimensions, surface treatments, marking and packaging can be reviewed against your requirements. Supply a drawing or specification list so feasibility, inspection requirements and lead time can be confirmed before ordering.
Can I order samples or mixed sizes, and what is the lead time?
Sample and mixed-size requests can be reviewed. MOQ and dispatch timing depend on the selected specifications, stock availability and custom requirements. Send a size-and-quantity list for confirmation.
