Ask for point geometry to remain explicit on the item identification. A mixed shipment containing spiral flute taps needs distinct descriptions even where the thread/pitch and drive dimensions match.

HSS Metric Spiral Point Machine Tap
Keep the chip exit clear when sourcing metric taps for through-hole work.
HSS metric spiral point machine taps direct chips ahead of the cutting edge. This series covers 16 listed combinations from M2 × 0.4 to M24 × 3.0, with HSS and HSS-Co material descriptions. It addresses through-hole enquiries where forward chip clearance matters more than a helical-flute appearance.

Match pilot-hole preparation to the thread system, workpiece and agreed acceptance requirement.
The M6 × 1.0 entry has 66 mm overall length, 15 mm cutting length, 6 mm shank and 4.5 mm square. Confirm available travel and clearance beyond the far face, as well as the holder dimensions.

PRODUCT SELECTION
Application, Chip Path & Selection Limits
Match the component and operation
For through holes, establish an unobstructed chip exit beyond the workpiece. A spiral point is a cutting-point feature; it is different from a spiral flute that returns chips towards the entrance. Match the workpiece grade and tool material before choosing operating conditions.
Check the operating boundary
A closed-bottom hole needs a separate assessment of unused depth and chip volume. Do not specify this range as a direct blind-hole replacement merely because its holder dimensions match another tap.
PRODUCT SELECTION
Compare the Adjacent Product Families
| Product family | Selection boundary to review |
|---|---|
| HSS Metric Spiral Flute Machine Tap | General metric return-chip spiral flute series for blind-hole selection; retain the published dimensions. |
| DIN 371 HSS Spiral Point Machine Tap | For DIN 371 through-hole work, specify the point form as carefully as the shank size. |
| DIN 376 HSS Spiral Point Machine Tap | Separate reduced-shank reach and forward chip clearance in a DIN 376 point-tap enquiry. |
Keep the selected family, thread designation and dimensional reference together. Shared nominal sizes or drive shapes do not establish interchangeability.
WORKSHOP & SUPPLIER REVIEW
Workshop, Material Handling & Order Organisation
A through-hole point-tap order depends on more than a nominal metric label. Bring the point configuration, component thickness and exit drawing into the supplier review so the requested geometry stays linked to the purchasing record.
Bar-stock handling
Carry the HSS / HSS-Co requirement with the item drawing when discussing material preparation for this range.
Component feed and transfer
Keep the approved item identity and dimensional revision with components during order discussions. Use the exact thread and drive dimensions to distinguish similar tools.
Plan the order around the approved item
- Define the thread and application using this product’s selection table.
- Compare the tool interface and cutting geometry with the sample or drawing.
- Agree sample acceptance, quantities by size and the requested pack arrangement.
- Reference the same approved item and revision for replenishment.
QUALITY & SAMPLE ACCEPTANCE
Quality Review for the Selected Specification
Review the actual point geometry and the specified thread together. Sample approval should also address the shank/square fit and the chip path beyond the component; a photograph of the shaft alone cannot confirm the cutting point.
Use the following items to define the sample and order acceptance brief.
| Review item | What to agree | Procurement risk addressed |
|---|---|---|
| Thread identification | Nominal size, required pitch and finished-thread requirement | Avoid the wrong thread family or pitch |
| Dimensions and holding | The M6 × 1.0 entry has 66 mm overall length, 15 mm cutting length, 6 mm shank and 4.5 mm square. Confirm available travel and clearance beyond the far face, as well as the holder dimensions. | Avoid holder mismatch, insufficient reach or unintended substitution |
| Geometry / set identity | Review the actual point geometry and the specified thread together. Sample approval should also address the shank/square fit and the chip path beyond the component; a photograph of the shaft alone cannot confirm the cutting point. | Avoid the wrong cutting form or incomplete member sequence |
| Sample acceptance plan | Agree the reference drawing, acceptance method and sampling requirement for the application | Make sample approval and repeat-order review refer to the same item |
PROCUREMENT & REPLENISHMENT
Packaging, Custom Requests & Bulk Purchasing
Keep the packing brief specific
For through-hole production orders, attach the component thickness and exit-clearance drawing to the size list. Identify HSS or HSS-Co on the requested order line and keep the general metric series separate from DIN 371/376 replacements.
Marking, packs & repeat orders
Ask for point geometry to remain explicit on the item identification. A mixed shipment containing spiral flute taps needs distinct descriptions even where the thread/pitch and drive dimensions match.
Turn the selection into a clear purchasing list
Keep the chip exit clear when sourcing metric taps for through-hole work.
SELECTION & BUYER QUESTIONS
Product Questions
What are spiral point taps for?
They are commonly selected for through-hole threading because the point directs chips forwards. The tool needs room for those chips to leave beyond the threaded section.
How is a spiral point different from a spiral flute?
A spiral point pushes chips ahead; a spiral flute carries chips back towards the shank. The names describe different geometry, even where the nominal thread and holder dimensions match.
Can a spiral point tap thread a blind hole?
Some setups allow extra depth for the lead and forward-moving chips, but that must be checked for the particular tool and workpiece. For a normal blind-hole enquiry, compare the spiral flute series first.
Can I retain the holder used for the general metric spiral flute tap?
Compare d, k and clamping length for the exact size. Matching drive dimensions can support a holder review, but they do not establish that the two geometries suit the same hole.
Is this the DIN 371 spiral point series?
No. This is the general metric series. If the purchase order specifies DIN 371 or DIN 376, use the corresponding dimensional page and compare each required size.
What information makes a through-hole quotation usable?
Send size and pitch, workpiece grade, component thickness, required thread depth, exit clearance, holder details and quantity by size. Add the requested material and pack arrangement.
