Source the aluminium-focused M35 series without confusing tool grade with thread size.
This aluminium-focused spiral flute tap series uses M35 cobalt high-speed steel and covers seven metric combinations from M3 × 0.5 to M12 × 1.75. It is a separate choice for buyers whose workpiece is an aluminium alloy, rather than a general mixed-material tap assortment.
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) |
|---|---|---|---|---|---|
| M3x0.5 | 46 | 11 | 4 | 3.2 | 2.5 |
| M4x0.7 | 52 | 13 | 5 | 4 | 3.3 |
| M5x0.8 | 60 | 16 | 5.5 | 4.5 | 4.2 |
| M6x1.0 | 62 | 19 | 6 | 4.5 | 5 |
| M8x1.25 | 70 | 22 | 6.2 | 5 | 6.8 |
| M10x1.5 | 75 | 24 | 7 | 5.5 | 8.5 |
| M12x1.75 | 82 | 29 | 8.5 | 6.5 | 10.3 |
Match pilot-hole preparation to the thread system, workpiece and agreed acceptance requirement.
Overall lengths run from 46 to 82 mm. The M6 × 1.0 item has L 62 mm, Lc 19 mm, d 6 mm and k 4.5 mm; do not substitute the general M6 spiral flute item without comparing reach and cutting length.
The spiral flute form helps carry aluminium chips towards the entrance. State the exact alloy and condition, drilled-hole depth and full-thread requirement when reviewing a blind-hole application.
M35 identifies the tool material grade; it is not an M35 thread designation in this range. The listed size range stops at M12. Surface colour alone does not establish a coating or a particular aluminium machining result.
| 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. |
| HSS-Co Metric Thread Forming Tap | Specify a forming-hole diameter before treating chipless threading as a cutting-tap replacement. |
| DIN 371 HSS Spiral Flute Machine Tap | Choose a DIN 371 blind-hole tool using both flute form and reinforced-shank dimensions. |
Keep the selected family, thread designation and dimensional reference together. Shared nominal sizes or drive shapes do not establish interchangeability.
An aluminium-focused assortment needs the M35 tool-material requirement tied to the actual alloy enquiry. Use the supplied workshop views to discuss the reference item and order organisation without treating product appearance as a material certificate.
For aluminium-series packs, separate the M35 material description from the metric thread designation. Send the desired individual or mixed-size contents for review; similar silver views are not separate pack components.
Carry the M35 cobalt high-speed steel 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.
Link the M35 material requirement to the approved sample and purchasing specification. Review flute condition, thread dimensions and holder fit for the aluminium job, with the required surface treatment specified separately.
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 | Overall lengths run from 46 to 82 mm. The M6 × 1.0 item has L 62 mm, Lc 19 mm, d 6 mm and k 4.5 mm; do not substitute the general M6 spiral flute item without comparing reach and cutting length. | Avoid holder mismatch, insufficient reach or unintended substitution |
| Geometry / set identity | Link the M35 material requirement to the approved sample and purchasing specification. Review flute condition, thread dimensions and holder fit for the aluminium job, with the required surface treatment specified separately. | 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 |
Build an aluminium assortment around alloy requirements and the seven actual size-and-pitch combinations. Keep M35 in the tool-material field and the metric designation in the thread field, then identify pack quantities and customer marking requests separately.
For aluminium-series packs, separate the M35 material description from the metric thread designation. Send the desired individual or mixed-size contents for review; similar silver views are not separate pack components.
Source the aluminium-focused M35 series without confusing tool grade with thread size.
Here M35 is the cobalt high-speed steel grade. The thread sizes are M3 to M12, as listed individually in the table.
No. This page is the M35 aluminium-focused range with its own dimensions. For example, its M6 overall length is 62 mm, compared with 66 mm in the general series.
Send the alloy and condition first. Chip behaviour and the required thread depth still need to be matched to the actual application; aluminium alone does not define operating conditions.
No. Similar appearance photographs do not establish a set or separate finishes. Order the individual thread sizes and quantities required.
M12 × 1.75, with 82 mm overall length and 29 mm cutting length. Do not infer larger aluminium-specific sizes from other tap ranges.
Specify alloy, hole type, drilled and threaded depths, thread/pitch, holder dimensions and quantity. Identify M35 material and any surface or packaging requirement for review.
Send the selected thread designation, quantities and the application details below. Add a drawing or size list to keep the enquiry tied to the required configuration.
