Hand Tap set of 2 pieces DIN 2181 HSSE - M 10 x 1.0

Specific applications

Typical tasks include fine-threaded holes in brackets, mounting plates and housings according to the component drawing. The component drawing must specify the thread designation M10 × 1; check the material against the suitability information below.

In lighting manufacture, M10 × 1.0 is also used as a lamp thread for mechanical fastening, for example on matching lampholder components, threaded nipples and connectors. The set is used to produce corresponding internal threads in suitable materials. This refers to the fastening thread of the light fitting, rather than the E14 or E27 thread of the lamp itself.

On bicycles, M10 × 1.0 is a common size for attaching conventional rear derailleurs to the derailleur hanger. One specific application is producing a corresponding internal thread or professionally assessed reworking of a slightly damaged derailleur mounting thread. This does not automatically refer to attaching the derailleur hanger to the frame. A stripped thread with missing material cannot be restored by recutting alone.

In automotive and motorcycle applications, M10 × 1.0 also occurs on certain hollow-bolt/banjo connections. A matching internal thread can be produced in connecting or adapter components designed for this purpose and made from suitable materials. In addition to the right-hand thread, the engagement length, connection geometry and sealing faces are decisive for component design. The same thread size alone does not authorise reworking of an existing brake or hydraulic component.

Existing threads can be recut if their size, pitch and condition allow it. This does not restore missing material or severely damaged threads.

Suitable materials

HSS-E is intended for difficult-to-machine materials and steels up to approximately 1,200 N/mm² as well as general use. These include unalloyed and alloy steels, case-hardening and quenched and tempered steels, heat-resistant steels, grey cast iron, selected aluminium and copper alloys, and titanium alloys.

The following table shows example materials and represents only a selection of the suitable materials.

Chamfer of the two cutting stages

The chamfer is the front cutting section in which the thread profile is built up gradually.

1. Secure the workpiece
   Clamp the workpiece securely so that it cannot rotate. The hole must be readily accessible so that the tap can be started squarely and guided in line with the hole axis throughout the operation.
2. Prepare the tapping drill hole
   Drill the tapping drill hole for M10 × 1 to the recommended diameter of 9 mm. You can find a clear overview of selection and calculation in the VÖLKEL article Calculating the tapping drill hole size for taps. Blind holes must also be drilled sufficiently deeper.
3. Deburr and clean the hole
   Remove the burr at the hole entrance and clear away loose drilling chips. A clean, lightly chamfered hole makes it easier to start the taper tap squarely and prevents damage to the first thread.
4. Tapping with the taper tap
   Clamp the taper tap in a suitable tool holder and align it precisely with the hole axis. Apply sufficient cutting lubricant for tapping to the tool and hole. Turn the taper tap into the workpiece with steady pressure.
5. Tapping with the bottoming tap
   Finally, insert the bottoming tap and apply sufficient cutting lubricant again. The bottoming tap produces the complete internal thread profile. Work with steady movements and avoid excessive force, particularly when the bottoming tap reaches the bottom of a blind hole.
6. Check the thread
   Remove chips and residual cutting lubricant from the finished thread. Then check the thread size and ease of engagement using a suitable inspection tool, such as a GO/NO-GO thread plug gauge if compliance with the required tolerance must be demonstrated.

What is the difference between M10 × 1.0 and M10 × 1.5?

Both threads have a nominal diameter of 10 mm. However, this fine-thread set produces a 1.0 mm pitch instead of the 1.5 mm pitch of the M10 coarse thread. Use it only for the matching mating thread.

Which tapping drill do I need for M10 × 1?

For M10 × 1, the recommended tap drill diameter is 9 mm. Guidance on preparing the tapping drill hole.
As an approximation: tap drill diameter ≈ nominal diameter − pitch. Here: 10 mm − 1 mm = 9 mm. The recommended drill diameter of 9 mm remains decisive.

Can I use this set to change an M10 coarse thread into a fine thread?

An existing M10 coarse thread cannot simply be converted to M10 × 1.0 by recutting. The different thread paths do not leave a reliably complete new profile. Such a repair requires a separate solution.

Which materials is HSS-E intended for?

HSS-E offers high edge retention for difficult-to-machine materials and steels up to 1,200 N/mm² as well as general use. The material overview in the first section shows the assigned example materials. Comparing tool materials for hand taps.

Are three tools included for the M10 fine thread?

No. Item 56336 is a two-piece set consisting of taper tap 56336-1 and bottoming tap 56336-2. A second tap is not included.

What thread tolerance applies to item 56336?

The specified thread tolerance is ISO2 (6H). ISO2 denotes the tool tolerance class; 6H is the associated internal thread tolerance. If necessary, check compliance with the required thread tolerance using a suitable GO/NO-GO thread plug gauge.

Is the HSS-E version of this fine-thread set steam-treated?

HSS-E is specified for item 56336, with no steam-treated surface. The designations HSS-E and HSS-E VAP must not be treated as equivalent during selection.

Which tap wrench fits this hand tap?

The holder must securely grip the 5.5 mm square drive. Compare this value with the specified clamping range of the tap wrench or tool holder. Choosing the right tap wrench.

Which individual tools can I reorder for item 56336?

The set includes taper tap 56336-1, bottoming tap 56336-2. When reordering, also compare the standard, thread and tool material.
