THREADING TOOLS / INDUSTRIAL PROCUREMENT

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.

This fully ground HSS straight flute tap range uses a 1/4-inch (6.35 mm) hex drive. Seven metric size-and-pitch combinations cover M3 × 0.5 to M12 × 1.75, with 57–77 mm overall lengths. It is a tapping tool for a prepared hole, not a combined drill tap.

Match pilot-hole preparation to the thread system, workpiece and agreed acceptance requirement.

The M6 × 1.0 row has L 67 mm, Lc 26 mm, d 7.2 mm and k 6.35 mm. Compare the full tool and interface dimensions before replacing a square-drive machine tap.

Application, Chip Path & Selection Limits

Match the component and operation

Select the hole preparation and thread requirement first, then check chip behaviour for the workpiece and hole form. The hex interface provides a defined drive dimension but still needs a suitable controlled tapping setup.

Check the operating boundary

A hex shank does not prove impact-driver suitability or eliminate alignment and reversal requirements. The dark appearance in the product views does not identify a particular coating.

Compare the Adjacent Product Families

Product familySelection boundary to review
HSS 1/4 Inch Hex Shank Spiral Flute TapCombine a defined hex interface with a return-chip flute form for blind-hole selection.
Long Series HSS Hex Shank Drill TapCompare drilling length, thread length and reach before choosing the long hex-shank combination tool.
HSS Metric Straight Flute Machine TapBuild 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, Material Handling & Order Organisation

For this hex-drive range, the important order boundary is tap-only versus combined drilling and tapping. Review the prepared-hole operation and straight flute form alongside the drive specification.

Storage racks and machine area

Use tap-only and straight flute with the metric size/pitch in the proposed identification. A shared 1/4-inch drive should not make these items indistinguishable from combination drill taps in the same shipment.

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

  1. Define the thread and application using this product’s selection table.
  2. Compare the tool interface and cutting geometry with the sample or drawing.
  3. Agree sample acceptance, quantities by size and the requested pack arrangement.
  4. Reference the same approved item and revision for replenishment.

Quality Review for the Selected Specification

Use the sample to verify the hex interface and the complete tapping geometry. Do not accept a combination drill tap on the basis of an identical drive size.

Use the following items to define the sample and order acceptance brief.

Packaging, Custom Requests & Bulk Purchasing

Keep the packing brief specific

Distinguish hex-drive straight flute taps from hex-drive drill taps in the stock description. Include the prepared-hole requirement, exact metric pitch and holder information in a mixed power-tool accessory enquiry.

Marking, packs & repeat orders

Use tap-only and straight flute with the metric size/pitch in the proposed identification. A shared 1/4-inch drive should not make these items indistinguishable from combination drill taps in the same shipment.

Product Questions

Does this tap drill its own pilot hole?

No. This is the straight flute tap-only family. A combined drill tap includes a separate drilling section and is listed on another page.

What does 1/4-inch mean on this metric tap?

It identifies the hex drive, equal to 6.35 mm. The working threads remain the metric size-and-pitch combinations in the table.

Can the hex tap be used in impact mode?

No impact rating is established by the hex shape. Provide the machine, holder and operating mode for selection review.

What are the M6 straight-flute hex dimensions?

L 67 mm, Lc 26 mm, listed diameter d 7.2 mm and hex k 6.35 mm. Check available engagement and access with the holder.

Is it the same as the 80 mm hex spiral flute tap?

No. This range has straight flutes and 57–77 mm overall lengths. The separate spiral flute family is listed at 80 mm throughout.

How should a distributor distinguish it from a hex drill tap?

Label it tap-only, straight flute, metric size/pitch and 1/4-inch hex. Keep the pilot-hole requirement and quantity with the order line.
