DIN 352 HSS Three Piece Hand Tap Set
Specify the DIN 352 three-piece set and its dimensional series—not just three metric taps.
The DIN 352 HSS hand tap set range contains 18 listed nominal metric sizes from M2 to M20. Each product is a three-piece progressive hand-tapping set. The short dimensional family and its size-specific shank/square values distinguish it from the other three-piece hand tap range.

- Three-piece set for progressive hand tapping.
- DIN 352 dimensional series.
- HSS construction and square drive ends.
- Listed metric sizes: M2–M20.

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) |
|---|---|---|---|---|---|
| M2 | 36 | 8 | 2.8 | 2.1 | 1.6 |
| M2.5 | 40 | 9 | 2.8 | 2.1 | 2.05 |
| M3 | 40 | 11 | 3.5 | 2.7 | 2.5 |
| M3.5 | 45 | 13 | 4 | 3 | 2.9 |
| M4 | 45 | 13 | 4.5 | 3.4 | 3.7 |

| M20 | 95 | 34 | 16 | 12 | 17.5 |
Match pilot-hole preparation to the thread system, workpiece and agreed acceptance requirement.
M6 is listed at L 56 mm, Lc 19 mm, d 6 mm and k 4.9 mm. The other three-piece range lists M6 at L 62 mm and k 4.5 mm, so the two sets are not dimensional equivalents.

PRODUCT SELECTION
Application, Chip Path & Selection Limits
Match the component and operation
Choose the required thread and manual access first, then review the set’s lead sequence for the hole and full-thread depth. Use the listed dimensions to match the hand holder and component clearance.
Check the operating boundary
A three-piece set does not establish a precise taper/plug/bottoming sequence without the member specification. Pitch must be supplied with the nominal size, and a finishing member still needs bottom clearance.
PRODUCT SELECTION
Compare the Adjacent Product Families
| Product family | Selection boundary to review |
|---|---|
| HSS Metric Three-Piece Hand Tap Sets | Keep a three-piece hand-tapping set together through ordering, sample approval and replenishment. |
| HSS Two-Piece Metric Tap Sets | Keep two-member lead geometry and set completeness explicit in a metric hand-tap order. |
| DIN 371 HSS Straight Flute Machine Tap | Keep the DIN 371 shank dimensions explicit when a customer asks for a straight-flute replacement. |
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
For DIN 352 sets, the three-member sequence and the dimensional family are both procurement controls. Review a complete reference set rather than approving three tools solely by their nominal metric labels.
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 the complete three-piece sequence and drive dimensions. Pilot-hole preparation and any atypical catalogue entry should be resolved against the component requirement before sample tapping is agreed.
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 | M6 is listed at L 56 mm, Lc 19 mm, d 6 mm and k 4.9 mm. The other three-piece range lists M6 at L 62 mm and k 4.5 mm, so the two sets are not dimensional equivalents. | Avoid holder mismatch, insufficient reach or unintended substitution |
| Geometry / set identity | Approve the complete three-piece sequence and drive dimensions. Pilot-hole preparation and any atypical catalogue entry should be resolved against the component requirement before sample tapping is agreed. | 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 complete DIN 352 sets by nominal size and specified pitch. Keep the three-member identity, set count and pack arrangement together so replenishment does not turn into a mixture of incompatible finishing and starting taps.
Marking, packs & repeat orders
State three-piece DIN 352 sets, selected pitch and set count in the packing brief. Mark any replacement-member enquiry separately so a mixed order does not conceal an incomplete set.
Turn the selection into a clear purchasing list
Specify the DIN 352 three-piece set and its dimensional series—not just three metric taps.
SELECTION & BUYER QUESTIONS
Product Questions
How is this DIN 352 set different from the other three-piece range?
Its dimensions differ. At M6 it is 56 mm overall with a 4.9 mm square, versus 62 mm and 4.5 mm in the other range.
Does the set contain three different sizes?
No. It is a three-piece progressive set for one selected thread size. A mixed-size assortment is a separate packing request.
Are all pitches specified by the nominal M labels?
No. The table gives nominal M sizes. Include the required pitch on every set order line.
Can the third tap finish a blind thread without any bottom allowance?
No. Lead length and bottom clearance must be reviewed for the actual finishing requirement. Supply drilled and full-thread depths.
What is the listed size range for DIN 352 sets?
Eighteen entries from M2 through M20. Use the individual length and holder dimensions rather than inferring dimensions from the endpoints.
What should be confirmed before ordering replacement members?
The approved set’s exact thread/pitch, member identity and lead arrangement. Supply a sample or drawing to avoid mixing members from different dimensional series.
