7*1/set carbon steel manual laboratory punch rubber stopper puncher plug hole punch laboratory drilling tools
Specification:
Material: carbon steel
Function:
The perforator is specially used to drill holes in the rubber plug, which is convenient when conducting experiments to obtain gas.
Product care and maintenance:
1. When perforating, do not hit the handle with a hammer or other tool, as this will damage the perforator instead of penetrating the hole.
2. After use, clean the stains, spread the butter on the edge and put it in a ventilated and dry place. Avoid direct contact with acid, alkali and salt.
3. With prolonged use, the cutting edge becomes blunt. You can restore this with a multifunctional file, so that it becomes sharp again.
