THREADING TOOLS / INDUSTRIAL PROCUREMENT
HSS Metric Three-Piece Hand Tap Sets
Keep a three-piece hand-tapping set together through ordering, sample approval and replenishment.
This HSS metric hand tap range is supplied as three-piece sets across nine size-and-pitch combinations, M2 × 0.4 to M12 × 1.75. Its listed dimensions distinguish it from the DIN 352 three-piece range. Purchase the set as a defined item rather than treating three photographs as three unrelated stock choices.

Sizes, Dimensions & Drive Interface
Dimensions are in millimetres except thread designations, drive labels and lead counts. Read each column with the dimension reference below.
| Thread / designation | Overall length L (mm) | Working / cutting length Lc (mm) | Listed diameter d (mm) | Square / drive k (mm) | Pilot reference (mm) |
|---|---|---|---|---|---|
| M2x0.4 | 40 | 12 | 3 | 2.5 | 1.60 |
| M2.5x0.45 | 44 | 14 | 3 | 2.5 | 2.10 |
| M3x0.5 | 46 | 11 | 4 | 3.2 | 2.50 |
| M4x0.7 | 52 | 13 | 5 | 4 | 3.30 |
| M5x0.8 | 60 | 16 | 5.5 | 4.5 | 4.20 |
| M6x1.0 | 62 | 19 | 6 | 4.5 | 5.00 |
| M8x1.25 | 70 | 22 | 6.2 | 5 | 6.80 |
| M10x1.5 | 75 | 24 | 7 | 5.5 | 8.50 |
| M12x1.75 | 82 | 29 | 8.5 | 6.5 | 10.30 |
Match pilot-hole preparation to the thread system, workpiece and agreed acceptance requirement.
The M6 × 1.0 set lists L 62 mm, Lc 19 mm, d 6 mm and k 4.5 mm. The DIN 352 M6 set has a different overall length and square dimension.

PRODUCT SELECTION
Application, Chip Path & Selection Limits
Match the component and operation
Use progressive hand tapping where the workpiece, access and manual alignment suit the operation. Include hole type and the required full thread so the lead arrangement of the three tools can be reviewed.
Check the operating boundary
A three-piece description alone does not establish the exact lead sequence or bottoming clearance. Confirm the member identification with the set requirement; a bottoming label is not a promise of thread to the physical bottom.
PRODUCT SELECTION
Compare the Adjacent Product Families
| Product family | Selection boundary to review |
|---|---|
| DIN 352 HSS Three Piece Hand Tap Set | Specify the DIN 352 three-piece set and its dimensional series—not just three metric taps. |
| HSS Two-Piece Metric Tap Sets | Keep two-member lead geometry and set completeness explicit in a metric hand-tap order. |
| HSS Metric Straight Flute Machine Tap | Build a metric assortment around the actual shank and square dimensions—not thread size alone. |
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
The procurement unit here is a complete three-piece set. Review how the three member identities, selected thread and reference dimensions will be carried from sample approval into set-count and replacement enquiries.
Bar-stock handling
Carry the HSS 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. Separate set members and complete-set quantities.
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
Approve a complete reference set, including the identity and sequence of its three members. Check the agreed thread, lead arrangement and drive dimensions; a count of three tools does not verify a correct progressive set.
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 set lists L 62 mm, Lc 19 mm, d 6 mm and k 4.5 mm. The DIN 352 M6 set has a different overall length and square dimension. | Avoid holder mismatch, insufficient reach or unintended substitution |
| Geometry / set identity | Approve a complete reference set, including the identity and sequence of its three members. Check the agreed thread, lead arrangement and drive dimensions; a count of three tools does not verify a correct progressive set. | 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
Order by complete set count, then thread size and pitch. Send a packing or replacement-member requirement separately so three-piece sets remain complete and identifiable when a distributor breaks down an incoming shipment.
Marking, packs & repeat orders
Describe the three-member contents in a proposed set packing list and state how many complete sets are needed per size. Identify any loose-member request separately from an order for complete sets.
Turn the selection into a clear purchasing list
Keep a three-piece hand-tapping set together through ordering, sample approval and replenishment.
SELECTION & BUYER QUESTIONS
Product Questions
What is included in this hand tap product?
The product is a three-piece HSS metric hand tap set for a selected thread size. Confirm the member identification and lead sequence in the purchase specification.
Is this the same as a DIN 352 hand tap set?
No. The listed dimensions differ. For M6, this series has 62 mm overall length and a 4.5 mm square, while the DIN 352 entry has 56 mm and 4.9 mm respectively.
Do three taps mean three different thread sizes?
No. Specify the selected size for the set. Do not treat the three members of a progressive set as a mixed-size assortment.
Can the final tap make a thread right to the bottom?
A cutting lead and bottom clearance remain necessary. Provide drilled and required threaded depths so the finishing requirement can be assessed.
Which metric set sizes are listed?
Nine combinations from M2 × 0.4 through M12 × 1.75. The pitch is part of the set designation, not an optional note.
How should missing-member replacements be requested?
Identify the approved set, thread/pitch and the particular member with a photo or sample. Do not request an unspecified third tap and assume its lead matches the original set.
