Request short-series identification with the complete metric size/pitch. Keep ANSI as a source-family reference where needed in purchasing documents, without using it to relabel the tools as UNC.
Choose the short metric combination series by its actual dimensions, not its catalogue label.
This short-series HSS drill tap combines drilling, tapping and chamfering with a 1/4-inch hex drive. Six metric combinations run from M3 × 0.5 to M10 × 1.5. Overall lengths are 53.7–59 mm, creating a separate dimensional choice from the long and compact series.
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) | Drill length (mm) | Thread length (mm) | Hex shank | Catalogue series label |
|---|---|---|---|---|---|
| M3x0.5 | 53.7 | 6.5 | 11 | 1/4in(6.35mm) | ANSI |
| M4x0.7 | 54 | 7.6 | 10.5 | 1/4in(6.35mm) | ANSI |
| M5x0.8 | 58 | 8.7 | 14 | 1/4in(6.35mm) | ANSI |
| M6x1.0 | 58 | 8.8 | 14 | 1/4in(6.35mm) | ANSI |
| M8x1.25 | 59 | 10 | 15 | 1/4in(6.35mm) | ANSI |
| M10x1.5 | 58.5 | 12 | 14 | 1/4in(6.35mm) | ANSI |
Review the drill and thread sections together with component thickness and the required cutting sequence.
M6 × 1.0 has 58 mm overall length, 8.8 mm drill length and 14 mm thread length. M10 × 1.5 has a 58.5 mm overall length, so do not assume the range grows monotonically with diameter.
For access-limited work, compare the tool’s overall reach and the drill-to-thread transition with component thickness. Keep the application material and required full thread in the selection brief.
The catalogue’s ANSI label does not make these UNC tools: the listed threads are metric. No universal thickness or impact-operation capability follows from the short-series name.
| 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.
The short-series label must stay attached to its actual dimensional table. Review the six listed metric entries against the intended component thickness so a shared hex drive does not conceal an unintended length substitution.
Request short-series identification with the complete metric size/pitch. Keep ANSI as a source-family reference where needed in purchasing documents, without using it to relabel the tools as UNC.
Carry the HSS requirement with the item drawing when discussing material preparation for this range.
Keep the approved item identity and dimensional revision with components during order discussions. Use the exact thread and drive dimensions to distinguish similar tools.
For sample comparison, record the drilling length and transition location as well as the finished thread. A matching hex and M-size can conceal a different cutting sequence and available reach.
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 × 1.0 has 58 mm overall length, 8.8 mm drill length and 14 mm thread length. M10 × 1.5 has a 58.5 mm overall length, so do not assume the range grows monotonically with diameter. | Avoid holder mismatch, insufficient reach or unintended substitution |
| Geometry / set identity | For sample comparison, record the drilling length and transition location as well as the finished thread. A matching hex and M-size can conceal a different cutting sequence and available reach. | 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 |
Use the short-series dimensions as part of the SKU specification. In a distributor assortment, separate these six sizes from the long and compact families even if the hex size and thread labels are shared.
Request short-series identification with the complete metric size/pitch. Keep ANSI as a source-family reference where needed in purchasing documents, without using it to relabel the tools as UNC.
Choose the short metric combination series by its actual dimensions, not its catalogue label.
No. The table lists metric threads from M3 × 0.5 to M10 × 1.5. Order by the actual thread designation and dimensions rather than inferring thread form from a series label.
Overall length is 58 mm, drill length 8.8 mm and thread length 14 mm, with a 6.35 mm hex shank.
No. At M10 the short series is 58.5 mm overall, while the compact series is 64 mm. Compare the required size, not just the family names.
No M12 entry is listed here. The long and compact families have separate M12 entries and must be checked independently.
Compare thickness with the drilling section and the point-to-thread transition, allowing for exit clearance. Supply the drawing; do not use overall length as the limit.
Thread/pitch, overall length, drill length, thread length, 1/4-inch hex, material and quantity. Add the component thickness and packing requirement to the RFQ.
