HSS Square Drive Combined Drill Tap
Match the square-drive combined tool to the holder drawing before replacing a hex-shank drill tap.
This HSS combined drill-and-tap range has a square drive end and seven nominal metric entries from M3 to M12. Its table lists overall length, a shank-length field, cutting length, diameter and square-end width. It is a separate interface family from the 1/4-inch hex tools.

- Combined drilling and thread cutting.
- Size-specific square drive ends.
- Seven nominal metric entries, M3–M12.
- 53–100 mm listed overall lengths.
PRODUCT SELECTION
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 (mm) | Shank length, as labelled (mm) | Cutting length (mm) | Diameter, as labelled (mm) | Square end (mm) |
|---|---|---|---|---|---|
| M3 | 53 | 5.5 | 12 | 3.15 | 2.5 |
| M4 | 53 | 5.5 | 15 | 4 | 3.15 |
| M5 | 65 | 7 | 15 | 5 | 4 |
| M6 | 65 | 8 | 22 | 6.3 | 5 |
| M8 | 76 | 15 | 22 | 6.3 | 5 |
| M10 | 83 | 18 | 27 | 8 | 6.3 |
| M12 | 100 | 25 | 35 | 9 | 7.1 |
Use the labelled dimensions with the component and holder drawings.
The M6 entry gives 65 mm overall length, 8 mm shank length as labelled, 22 mm cutting length, 6.3 mm listed diameter and 5 mm square. Match those labels to a dimensioned drawing before ordering.

PRODUCT SELECTION
Application, Chip Path & Selection Limits
Match the component and operation
Review the complete holder interface and the component drawing for a combined drilling/threading operation. Request the exact pitch with the nominal size, as the listed table does not specify pitches.
Check the operating boundary
Do not reinterpret the table’s shank-length field as drill length. Holder compatibility must be checked with the round and square dimensions and available engagement, rather than assuming a universal ER-collet or tap-chuck fit.
PRODUCT SELECTION
Compare the Adjacent Product Families
| Product family | Selection boundary to review |
|---|---|
| Long Series HSS Hex Shank Drill Tap | Compare drilling length, thread length and reach before choosing the long hex-shank combination tool. |
| Compact HSS Hex Shank Drill Tap | Use size-specific drill and thread lengths to decide whether the compact geometry fits. |
| HSS 1/4 Inch Hex Shank Straight Flute Tap | Add a hex-drive tap to the assortment without confusing it with a drill-and-tap tool. |
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 square-drive combined family requires a holder drawing before interchangeability can be assessed. Keep the original dimension labels, requested pitch and drive engagement together during sample and order review.
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. 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
Approve the round-to-square interface and the interpretation of the labelled lengths with the reference sample. A general tap-chuck description is insufficient to establish clamping engagement.
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 entry gives 65 mm overall length, 8 mm shank length as labelled, 22 mm cutting length, 6.3 mm listed diameter and 5 mm square. Match those labels to a dimensioned drawing before ordering. | Avoid holder mismatch, insufficient reach or unintended substitution |
| Geometry / set identity | Approve the round-to-square interface and the interpretation of the labelled lengths with the reference sample. A general tap-chuck description is insufficient to establish clamping engagement. | 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 square-drive combined tools, send the holder drawing or sample alongside the required thread/pitch and component thickness. Keep each labelled dimension on the purchasing record to prevent a hex-drive tool from being treated as an equivalent.
Marking, packs & repeat orders
Identify the square-drive family separately from hex-shank combination tools. Attach the signed dimension reference to the pack brief, especially where a nominal M-size does not include the required pitch.
Turn the selection into a clear purchasing list
Match the square-drive combined tool to the holder drawing before replacing a hex-shank drill tap.
SELECTION & BUYER QUESTIONS
Product Questions
Is this a 1/4-inch hex-shank drill tap?
No. This series is described with a square drive end and size-specific square dimensions. The hex-shank combination tools are separate product families.
What pitch is supplied for an M6 entry?
The source table lists M6 without pitch. Include the required pitch in the RFQ so the exact thread can be agreed before ordering.
Is the shank-length column a drilling-length value?
No. It is labelled shank length in the source. Do not use it as a drill-depth value without a dimensioned tool drawing.
What are the M6 interface dimensions?
The M6 row lists a 6.3 mm diameter and a 5 mm square end. Confirm the labelled diameter, engagement length and holder details against the actual drawing.
Can it fit any ER collet or tapping chuck?
No universal fit is established. Check the clamping diameter, square-drive engagement, length and the holder manufacturer’s requirements.
What drawing details matter for a square-drive combination enquiry?
Show thread/pitch, overall and cutting lengths, round/square drive dimensions, component thickness and access. Include workpiece grade and quantity by size.
