Safe-Lock™ - Frequently asked questions

Answers to frequently asked questions about our Safe-LockTM system have all been put together for you here.

QUESTION:
Can an endmill with Safe-Lock™ shank also be clamped into a tool holder without Safe-Lock™ pins?

ANSWER:
Yes, tools with Safe-Lock™ shank can be clamped in every tool holder that is suitable for HA-shanks according to DIN 6535.

QUESTION:
Is the length of tools with Safe-Lock™ shank adjustable?

ANSWER:
Yes, the pull out protection Safe-Lock™ allows shifting the tool within the Safe-Lock™ groove without any problems, thus adjusting the demanded Z-length easily and quickly.

QUESTION:
How can I shrink in tools with Safe-Lock™?

ANSWER:
Corresponding to the application of tools with HA-shank, tools with Safe-Lock™ shank are put in the heated tool holder and are then shrinked in with a twisting movement.

QUESTION:
How can I get out broken tools with Safe-Lock™ shank from a Safe-Lock™ tool holder?


ANSWER:
The HAIMER unshrinking device (Order No. 80.126.00) helps to get out broken tools despite the  spiral-shaped Safe-Lock™ grooves without any problems.

QUESTION:
What advantages does the Safe-Lock™ system offer compared to the well-tried Weldon-clamping system?


ANSWER:
Due to the side clamping of the Weldon system, the tool is pushed off center, which causes reduced tool life, poor runout accuracy of up to 0,05 mm and therefore insufficient work piece surface finish. In comparison, HAIMER Safe-Lock™ provides, in addition to the pull out security, a very high runout  accuracy of < 0,003 mm. Only Safe-Lock™ allows a maximum metal removal rate combined with  absolute process reliability and precision!
