1 Application range, safety instructions and technical data
1.1 Application range, determined use
The quick-change tap holders type KSN/HD are mainly used on CNC machining centers, CNC turning machines and conventional machining centers with internal coolant-lubricant supply. The quick-change tap holders are marked by a red ring at the grip sleeve, see Picture 1, page 6. Normally, the quick-change tap holders are equipped with one of the following shanks: � Cylindrical shank acc. to DIN 6327 or ASME B 5.11 � Cylindrical shank acc. to DIN ISO 10889 (correspond to DIN 69880 or VDI 3425) or
DIN1835 B+E or ASME B 94.19 � Hollow taper shank (HSK) acc. to DIN 69893 A or DIN 69893 C � Taper shank acc. to DIN 69871 AD or B � ABS-clutch (System KOMET)
For the cutting range of each type, please refer to Table 1, page 6. The locking of the tool is executed via quick-change adapters type EM. The quick-change adapters must be chosen according to the size and the tool used, for more information please refer to chapter 2.5, page 9. The quick-change tap holders type KSN/HD are equipped with a length compensation on tension and on compression, pressure point mechanism and front release, see chapter 1.2 page 4. The quick-change tap holders type KSN/HD are suitable for internal coolant-lubricant supply up to 50 bar, see chapter 1.2, page 4. The non-determined use exempts the manufacturer from any liability!

1.2 Specification
Further features of the quick-change tap holders type KSN/HD are: • Small and compact overhang
• Length compensation in compression direction:
Compensates differences between spindle feed and the pitch of the thread to be produced. When using a quick-change adapter with overload clutch, the length compensation on compression compensates the spindle feed as soon as the overload clutch starts working.
• Length compensation in tension direction: Compensates differences between spindle feed and the pitch of the thread to be produced as well as an overrun of the spindle in the reversing point of the thread producing cycle.
• Front release: The front release protects the quick-change tap holder, the used quick-change adapter and the tool as well as the workpiece against damage caused by excessive axial tension. Such tension may occur if the length compensation path is exceeded due to afterrunning of the spindle at the point of reversal, or when the fast-feed function is activated before the tool has come free from the workpiece. In these situations the quick-change adapter disengages automatically from the quick-change tap holder and avoids expensive damages.
• Pressure point mechanism: The pressure point mechanism guarantees the safe cutting of the tool. Only when the effective occurring axial force exceeds the allowed cutting force, the pressure point mechanism releases the length compensation movement free.
⇒ Repeatable and regular thread depths are reached.
• Internal coolant-lubricant supply: Due to the special construction the coolant is guided from the spindle to the tool. The length compensation remains – independent from the coolant-lubricant pressure – in function. The max. coolant-lubricant pressure is 50 bar. Filtering of the coolant: <0,030mm
• High-quality surface protection against corrosion.
• Suited for right – and left-hand rotation
⇒ applicable on machines with reversion of rotation

1.3 Safety instructions
For all works, ie putting into operation, production or maintenance, please observe the details given in the operating instruction. All relevant safety regulations as well as local instructions are to be observed when working with the quick-change tap holders. Below please find some basic rules: - Please wear gloves during tool change to avoid injury.
- Basically change the tool yourself to avoid the sudden start of the spindle
caused by mis-operating.
- Hold the tool when loosening the tool clamping to avoid it falling down and damaging the tool and workpiece.
- Keep the tool adaptation clean.
- There are maximum values for cutting speeds and feed. Please observe such data.
- Please observe the maximum tool dimensions.
- Furthermore, the instructions of the tool manufacturers are valid!

2 Putting the quick-change tap holders into operation
2.1 Unpacking
- Take the quick-change tap holder from the plastic case - Clean the quick-change tap holder with a duster to remove any conservation oil Do not use any aggressive solvents.
Do not use any fibrous materials, ie steel wool.
⇒ The quick-change tap holder is now ready for operation! Exception: Type with hollow taper shank (HSK). Please refer to chapter 2.4, page 8, for how to put this quick-change tap holder into operation.
2.2 First putting into operation
For quick-change tap holders with HSK-shank (hollow taper shank) the coolant-
lubricant pipe must be mounted prior to putting into operation, see chapter 2.4, page 8. When working with internal coolant supply: The tap holders KSN/HD are made for coolant pressure up to max. 50 bar. Filtering of the coolant: <0,030mm.
The quick-change tap holders are inserted into the machine manually or – if provided – by the tool exchanger. The tool exchange must not be executed while the machine spindle rotates! - Only use tool shanks and tightening bolts suitable for the specific machine.
- Make sure the tool is correctly clamped.
⇒ Risk of accident by spinning of the tool! - Please see also the indications in the operating instruction of your machine
tool!
2.3 Reputting into operation
In case the quick-change tap holder is reput into operation – as described in chapter 4, page 16 – please carry out the following working steps:
1. Clean the quick-change tap holder with a duster to remove any conservation oil
Do not use any aggressive solvents. Do not use any fibrous materials, ie steel wool.
2. Check function of the length compensation: Tear and compress the quick-change tap holder at the grip sleeve, let go off the grip sleeve
→ the quick-change tap holder must return to its initial position
3. Exchange the quick-change tap holder into the machine as described in chapter 2.2

Type EM..-R Reducing adaptation for all EM types Application range: for the extension of the clamping range downwards
Working with internal coolant-lubricant supply:
For the following quick-change adapters it is necessary to use tools with oil channel:
EM, EM E-Lock, EM-U, EM-L, EM-UL, EM-Z, EM-L/ER/IKZ, EM-PGR
For the following quick-change adapters, tools without oil channel are used:
EM-IKZ, EM-U/IKZ The adaptation of the tool is carried out via a quick-change ball clamping system, except for EM-Z, EM-L/ER/IKZ , EM-PGR. The torque arising during the thread producing operation is transferred via the square integrated in the quick-change adapter. The adaptation of the dies is executed via mechanical locking. All quick-change adapters are suited for producing right- and left-hand threads. The quick-change adapter sizes for the appropriate quick-change tap holder may be taken from Table 1, page 6. The clamping diameter is defined by the used tool. Each diameter requires a separate quick-change adapter.
