TOOL BUYING GUIDES
Specify the bit. Count the supplied unit.
Two practical checks for a screwdriver-bit or tool-set enquiry.
01 / BIT FIT
PH2 describes the tip, not the whole bit.
Record the tip profile and size, overall bit length, shank interface and holder retention separately. Include the holder or driver model so the mating arrangement can be checked.
| Field | What to write | Why it matters |
|---|---|---|
| Working tip | For example PH2, H4 or T20 | Identifies the screw-side profile and size |
| Length | Overall bit length in mm | Keeps reach requirements distinct from tip size |
| Holder end | Shank shape, nominal size and stated form | Identifies the driver-side interface |
| Retention | Holder model and engagement / locking arrangement | Lets the supplier check the actual combination |
A real catalogue comparison
Bosch lists PH2 examples at 25 mm with ISO 1173 C6.3 (part 2607001511) and at 49 mm with ISO 1173 E6.3 (part 2607001528). Both use a nominal 1/4-inch external hex shank. The separate length and form fields make a more precise enquiry than “PH2 bit”. See the Bosch catalogue options.
Wera’s 815/1 holder specifies compatibility with C6.3 and E6.3 bits. Check the stated compatibility of your own holder in the same way. See the Wera holder reference.
These manufacturer examples explain catalogue fields. Specifications for a Vereyan enquiry come from the selected Vereyan option and its confirmed supplied packaging.

02 / SUPPLIED QUANTITY
A piece, a pack and a set are different units.
State the quantity in the unit shown for the selected option. Keep the number of sales packs separate from the number of tools or bits inside each pack.
| Enquiry | Clear quantity statement | Check before acceptance |
|---|---|---|
| Individual tool | 20 pieces of the specified option | Individual packaging and outer packing |
| Pack of identical bits | 3 packs × confirmed pieces per pack | All bits are the same selected size and length |
| Mixed tool set | 2 complete sets with the confirmed contents list | Every tip size, handle, holder and accessory count |
The quantities above are examples of how to write an enquiry. Use the published sales unit for the actual product. For a mixed set, request an itemised contents list; a photograph or a total piece count alone does not identify every supplied size.
In the listed ratcheting set, 38 counts the bits: 32 short and 6 extended. Enquiry quantities count complete sets, including the driver assembly and black case.
A set-enquiry checklist
- Handle and ratchet arrangement
- Every bit profile, size, length and quantity
- Holder, extension or adapter interfaces
- Case and individual set packaging
Keep the specification with your quantities.
The mixed enquiry list carries the listed option, sales unit and destination into the draft you review and send.
